CheMic – a chemical microscopy beamline – is a microfocus spectroscopy beamline dedicated to spatially-resolved X-ray fluorescence (XRF) and X-ray absorption spectroscopy (XAS) operating in the tender-to-hard X-ray energy regime (2-20 keV). The target user community is involved in a broad range of research fields such as environmental sciences and nanotoxicology, biogeochemistry and paleosciences, energy materials and biomedical research. It also includes industrial users focusing on applied research relevant for the food, mine and waste sectors. All these very diverse users share the need for spatially resolved investigation of heterogenous samples at microscopic level. CheMic will serve and attract new users but also complement and leverage the capabilities of existing beamlines (NanoMAX and Balder), strengthening the user base of MAX IV. This addition to MAX IV’s beamline portfolio will offer the opportunity for new developments (e.g., fluorescence detectors able to cope with high count rates) and at the same time provide crucial and currently missing microscale imaging capabilities.

Research at modern X-ray sources continues to develop our knowledge of the natural world in a wide range of fields, with a profound impact on the grand challenges of our industrial, economic and societal evolution. Of particular importance for X-ray science are free-electron laser (FEL) sources, providing extremely short radiation pulses at the highest achievable brilliance that enable unveiling the ultrafast dynamics of fundamental phenomena that cannot be studied by any other means. The Soft X-ray Laser (SXL) at MAX IV is an initiative by the Swedish FEL user community requesting enhanced capabilities at the MAX IV Laboratory to deliver coherent ultrashort pulses in the soft X-ray range. SXL will open up unique opportunities for research in atomic, molecular and optical science, chemistry, materials, condensed matter and life sciences, as described in the science case that was compiled and published in 2016. Based on this science case, a group of scientists and engineers from a number of Swedish universities and the MAX IV Laboratory has worked on the design of SXL, resulting in a recently published Conceptual Design Report. SXL builds on the existing MAX IV linear accelerator and will be placed in a building extension of the Short Pulse Facility. The main special features of SXL are the ability to provide short, femto- and attosecond duration, X-ray pulses with high intensity and variable polarization, and double X-ray pulses with different wavelengths and tunable time delay. In addition, SXL features an advanced laser infrastructure, where pump-probe experiments can be performed using photon pulses from a multitude of secondary sources in a wide wavelength range from the THz to the soft X-ray regime. SXL provides unique as well as complementary features to other FELs around the world and will place Sweden at the forefront of international X-ray research for years to come. At this stage, the project is ready to take the important step from concept to realization.

We propose to build a high-resolution tender and hard x-ray spectroscopy beamline in the energy range of 2-20 keV. The primary application of the beamline will be photoemission and X-ray based spectroscopies (x-ray emission, absorption, inelastic scattering, and Raman spectroscopies) on complex materials under vacuum, in situ and operando conditions. The proposed beamline will provide state-of-the-art and workhorse capabilities for the Swedish research community within both academia and industry in such fields as Catalysis, Low Density Matter, Atmospheric Chemistry, Atomic and Molecular Physics, Photovoltaics, Energy Storage, Nanodevices, Electrochemistry, Corrosion, and many others. It is clear from the information obtained by the working group while preparing this Expression of Interest that the demand for such facility at MAX IV by the Swedish and international communities is tremendous. The technical capabilities and the expertise present in the lab can ensure the success of such project. Moreover, the successful implementation of the goals presented in the Energy Materials and Technologies, Tackling Environmental Challenges, Quantum and Advanced Materials, Low Density Matter, and Industry Relationships sections of the ongoing MAX IV Strategy 2030 is clearly and strongly dependent from the immediate access to the tender and hard x-ray spectroscopy methods. We, therefore, think that it should be of primary MAX IV importance to ensure the proposed project is prioritized within the roadmap and supported in the process of seeking future funding.

GTiMAX will be a world-leading nano-to-micro-scale full-field imaging beamline focussed on multiscale analysis of the internal 3D structures of bulk materials and objects that will lead to significant advances in many areas of science. GTiMAX will be explicitly designed to enable these powerful 3D imaging capabilities to be extended to 4D (time-resolved 3D) imaging of structural evolution during in situ/operando experiments. This will allow direct observation and quantification of material responses to external and internal loads, e.g., during mechanical, thermal, hygrological or chemical loading. A key focus will be on the users who will be from a broad range of research areas and often with little or no synchrotron experience.The areas of application of GTiMAX are wide; including energy research, climate science, material science, additive manufacturing, bioengineering, clay science, civil engineering, chemistry, biology, earth/planetary science, food science, palaeontology, archaeology and cultural heritage.The key features of GTiMAX can be summarised as:

  • absorption and phase contrast imaging over 10-35+ keV on medium-sized (0.1 mm – 5 cm) samples;
  • multi-scale imaging (on the same sample) with 3D spatial resolution in the range 100 nm – 5 mm
  • focus on user-defined in-situ/operando experiments;
  • robust, user friendly operation with emphasis on high throughput and the full service (including sample environments and 3D & 4D data processing/analysis tools) required for the many users who will have little experience with synchrotron measurements and lack resources for data analysis;

GTiMAX will exploit the unique source characteristics of MAXIV through: (i) the high coherent fraction leading to better phase contrast images; (ii) the superior brilliance enabling fast tomography with better spatial resolution (and higher contrast) than at existing imaging beamlines for bulk materials.

MIRARI is a multi-endstation beamline for infrared (IR) spectroscopy and microscopy, placed on a bending magnet of the 1.5 GeV ring with a preliminary energy range 20-50000 cm-1 (2.5 meV-6.2 eV). The broad energy range, from THz to the UV, allows characterization of collective vibrational modes, molecular phonons, excitons & optical gaps in a wide range of samples.
At MIRARI three end stations will provide IR microscopy with spatial resolution from about 10 nm to 10 μm, as well as pure spectroscopy. Researchers from photonics to paleontology, and everyone in between, can perform top-class multimodal research here, as we believe everyone will benefit from a high-quality IR beamline! Together with strong user groups we want to develop specialized sample environments and advanced detection schemes compatible with our off-the-shelf end station solutions to truly be at the forefront of IR research.
Within Sweden, several universities and a number of strong actors push these developments, whilst international support from Nordic and Baltic communities is also present. The broad user base of MIRARI can in turn benefit from easy access to advanced instrumentation, not normally available to single groups.
Due to the non-prohibitive costs we plan for all modalities from the start, yet can sequentially bring them ‘online’ pending available resources. Lastly, due to its different contrast mechanism, IR pairs well with X-ray methods, and will therefore enhance the scientific scope of MAX IV for its users, as well as lower the threshold for communities and users new to the world of synchrotrons.

The main goal of the MedMAX project is to make a direct impact on clinical practice and modern industrial processes. To achieve this, we will build an instrument that can reveal the morphology and dynamics of living matter at length scales ranging from sub-micrometre resolution to several-centimetre field of view.
Synchrotron radiation based micro-computed tomography (SRμCT) is an imaging modality that can exploit the wave-like behaviour of x-rays, providing phase-contrast images with superior soft tissue contrast in comparison to standard CT. Due to the coherent properties of the synchrotron beam, optical refraction of the x-ray beam can be detected and fed into phase retrieval algorithms, in turn leading to a three dimensional electron density map of the sample.
In the past years, the scientific community behind MedMAX has grown, and includes a number of research fields where imaging of biological samples are relevant, such as: In-vivo imaging of small animals (insects, zebrafish, mice/rats), plant/food research, virtual histology of patient biopsies, biology, palaeontology, cultural heritage, dentistry etc. Many of these research fields involve both soft and hard matter, and thus fall both within the frame of MedMAX and that of the proposed GTiMAX for tomography of hard materials (see separate expression of interest).
This MedMAX expression of interest is based on the conceptual design report (CDR) developed at MAX IV. Though some of the details in that CDR are not up to date, the overall technical and scientific aims are:


  • Fast, dose balanced in-vivo and ex-vivo imaging.
  • High throughput fast tomography for studies involving a large number of samples, with a phase retrieval pipeline to ensure optimal image contrast in low contrast samples.
  • A versatile tomography endstation with a zoom option, where a local region of interest can be selected from a larger overview scan. In this way allowing for imaging of sparse features in large samples.

We propose a flux optimized beamline which combines the extreme brilliance of MAX IV with recent developments in ultrafast detector technology and flexible infrastructure and software for implementation of advanced sample environments for in situ/operando experiments across many research fields. This will constitute the first tailor-made beamline for ultrafast operando diffraction, and will cater to the needs of fundamental, applied and industrial research. Furthermore, a dedicated diffraction beamline will drastically increase the capacity of MAX IV to meet the need for powder and surface diffraction beyond the beamtime offered by DanMAX. Specifically, the strong industrial support for the proposal shows that its implementation will enable broad engagement of Swedish/Nordic industry in MAX IV. We particularly foresee the development of a strong industry/institute/university environment around the beamline and around operando diffraction in general. The science
cases defined directly target industrial needs and are clearly aligned with MAX IV strategy to provide impact in terms of enabling sustainable development and tackling environmental challenges. The beamline will provide both complementarity and synergies with DanMAX, and special attention has been given to how it will complement the Swedish beamline P21 at PETRA III. As it largely builds on existing MAX IV technology, the technical risk is low and it is expected to yield early scientific results.

Proposed experimental stations, instrumentations or upgrades

Submitted by: Foivos Perakis, Assistant Professor, Stockholm University, Sweden
The purpose of this EOI, Cross-XPCS, is to create a cross-beamline platform for measuring dynamic phenomena via XPCS in the strategic fields of lifes science, soft matter, energy and quantum technology. We propose to develop, coordinate and implement fast X-ray photon correlation spectroscopy (XPCS) capabilities at MAX IV using soft and hard X-rays with the aim to reach timescales of dynamic phenomena down to nanoseconds. The science cases address dynamics of proteins in crowded environments, molecular dynamics in aqueous environments, transport properties in energy storage materials and dynamics in new materials for information and quantum technology. The approach presented here aims for making ideal use of the unique coherence properties of MAX IV by coordinating and implementing new instrumentation developments in close collaboration between the user community and MAX IV.

The goal is to upgrade the endstation at Branch B of the FlexPES beamline with a Near-Ambient-Pressure (NAP) Electron Spectrometer, a new analysis chamber facilitating photoelectron spectroscopy (PES) experiments at high gas/vapor loads, and with versatile instrumentation allowing measurements on particle and liquid jets, as well as on supported samples in the gaseous and liquid environments. The new endstation would find its niche compared to the dedicated APXPS setups at SPECIES and HIPPIE by aiming at relatively simple and flexible sample environment for a wide range of experiments in different research areas.

The purpose of this EOI is to create a roll-on endstation for advanced x-ray magnetic dichroism and resonant x-rays scattering measurements on a wide range of materials. The sample environment will include a wide temperature range (initially 4-400K and with future upgrades even beyond that) as well as high and directionally varying magnetic fields (1-9T). This brings together users working on novel 2D quantum materials, topological magnetic heterostructures, strongly correlated electron materials and even exotic quantum spin liquids.
This endstation will provide the sample environment to a range of MAX IV beamlines in the soft x-ray range (with possible extension to hard x-rays at a later stage) that provide the necessary tunable x-ray polarization. In particular it also provides a link to similar scientific questions addressed with neutrons, therefore, potentially strengthening the suite of scientific facilities in Lund.

With this EoI we propose an upgrade of the angle-resolved photoemission spectroscopy (ARPES) capabilities at the Bloch beamline to include the following aspects: 1) nano focus of the light spot, 2) expansion of the sample preparation capabilities with micro manipulation tools enclosed in a glovebox, 3) in-vacuum or protected atmosphere transfer capabilities of samples into the ARPES endstation from either the sample preparation area or from outside MAX IV, 4) adding electrical connectors to the measurement environment to allow for electrical manipulation of the sample during ARPES measurements, such as gating or passing a current through the sample.
From a technical point of view, the proposed upgrades are considered to be relatively small. Yet, what we propose will have a considerable impact on the scientific output that can be achieved by allowing for high energy and angular resolution ARPES to be combined with high spatial resolution. Many ARPES beamlines around the world are currently moving towards a sub-micrometer spot size so the proposed capabilities are timely and would attract the interest of both the Swedish and the international ARPES communities. In addition to attracting the already established ARPES users, the upgrade has the potential to attract new, expanding, user groups within Sweden which are interested in applications concerning quantum material based electronic devices or materials for energy production and storage. The limited nano-ARPES capabilities at synchrotrons worldwide presents an excellent opportunity for MAX IV to become a leader in nano-ARPES with this proposal. We therefore believe that this EoI strategically fits into the MAX IV roadmap.

Polarization is a key property of light that is required for many user experiments relying on soft x-ray spectroscopies. It enables all flavours of linear and circular dichroism in x-ray absorption and photoemission for systems possessing structural or magnetic order. As the old undulator at the FlexPES beamline (transferred from the MAX II ring) has to be replaced in the nearest years to avoid potential reliability issues, the primary viable solution is to build an Elliptically Polarizing Undulator as a source of x-rays. This will broaden the range of techniques available to researchers at FlexPES by adding capabilities for natural and magnetic circular/linear dichroism, improve sensitivity of resonant and angular resolved photoemission to the orbital contribution in valence bands and facilitate studying orientation of chemical bonds by core-level photoemission. As a result, the suggested upgrade of the beamline is expected to strengthen the existing user community, attract new research groups and enable fail-free operation for years ahead.

This EoI aims at adding ambient pressure soft x-ray absorption spectroscopy (APXAS) to the portfolio of the HIPPIE and SPECIES beamlines for APXPS. In particular, we would like to implement time-resolved APXAS, as an excellent complement to the time-resolved APXPS capabilities that have been developed during the past years. The new APXAS capabilities are an add-on to what can be done using APXPS, i.e. users should benefit from being able to measure APXAS on the same samples as they do APXPS on, during the same beamtime and partly even simultaneously. Adding APXAS to the HIPPIE and SPECIES portfolio would be of very clear benefit to the existing and future user communities of HIPPIE and SPECIES, within the general material sciences and with particular focus on catalysis, corrosion, electrochemistry, photochemistry and thin layer growth. These areas relate directly to the societal challenges of climate change and energy provision that we are facing.

What is the Roadmap document?

The Roadmap is a separate document linked to the Strategy document. It details potential major items such as new or upgraded beamlines, instruments, and infrastructures. The focus of the document is the time frame from the present through 2030. Collaborators of the document will seek to implement and raise investments over the next decade.

In contrast to the Strategy document, which will change little – if at all – when finished, the Roadmap is an evolving document expected to undergo an annual review at least for the next three years.

The purpose of the Roadmap document is to present

  • A prioritized timeline for development of propose major items for enhancing the capabilities of MAX IV, as described above
  • How the proposed items will keep MAX IV at the international forefront of science
  • How the proposed items are aligned with the Strategy

The ambition of the Roadmap is to be partially accessible to potential funders and non-experts. The document should act as an operational guide for fundraising and have an expected timeline for implementing the items included.

Contributions to the Roadmap through Expressions of Interest

The call for “Expressions of Interest” (EoIs) invites brief proposals from the MAX IV community for new beamlines, instruments, capabilities, and upgrades proposed for the MAX IV Strategic Roadmap. EoIs will be evaluated as to the feasibility and scientific merit for potential inclusion in the roadmap. Inclusion of EoIs in the roadmap only implies a strategic prioritisation and development timeline; it does not imply a funding allocation. MAX IV, together with its partners, will separately seek to raise funding for items on the roadmap to develop MAX IV through 2030.

EoIs fall into three distinct types

  • Complete beamlines
  • Experimental stations, instrumentation, and upgrades
  • Other infrastructure and capabilities

An item warrants an EoI if any of these are true

  • The expected cost is on the order of 10 million SEK or more
  • The suggested expansion, construction, or upgrade impacts operations in a significant way, for example, if the implementation affects other beamlines and experiments
  • What is proposed is already funded but needs to be evaluated for feasibility and scientific relevance.

If you are doubting whether you should make a submission or not, please do not hesitate to contact us and ask via: . Suggestions for equipment, other upgrades and improvements that are part of operations, and outside of the roadmap process, should be directed to the MAX IV management, or the appropriate beamline managers.


The next deadline for submission is nominally after the 2022 User Meeting. We are getting a lot of requests to have another call in late spring, and this is under discussion.

The nominal deadline date, following the annual User Meeting, gives consortia the opportunity to present and discuss at the User Meeting, or in proximity to it. A submission is made by filling out the template and e-mailing it as a Word document or PDF to . Please, put “Submission of Expression of Interest” in the email subject line. Those who wish to organise and advertise workshops connected to the submission of an EoI, please see the Workshops page for more details and how MAX IV can help.

Contents of submission

The submission should be a maximum of five pages for a beamline, and three pages for the two other types.

Apart from ticking the appropriate boxes, the submission should contain the sections

  • Abstract
  • Background
  • Scientific case
  • User community and engagement
  • Technical specifications
  • State of the Art / Comparison to other beamlines or similar infrastructure (benchmarking)
  • Impact statement
  • Proposers
  • References

How the EoIs are evaluated

An EoI goes through three steps before being entered into the roadmap

  1. Technical feasibility report – MAX IV Management will will coordinate a check on the technical feasibility of EoIs, a short report of a couple of paragraphs for each, which will state if what is proposed is acheivable, improbable, or impossible. All EoIs are passed on to the next step.
  2. Individual evaluation by Roadmap Evaluation Committee – The committee is composed of 10-12 representatives from the MAX IV SAC, MAX IV MAC, Swedish universities, industry, and other international expertise.
    The categories are
    1. EoIs that are judged to be outstanding and of very high priority. These are eligible to be included in the Roadmap this round. There might be follow up questions to the proposers to be clarified before the final step.
    2. EoIs that are judged to be excellent and of high priority. These are also eligible to be included in the roadmap in this round. These might have more extensive follow up questions to be answered and clarified before the final step.
    3. EoIs that are judged to have insufficient grounds to go through this round. This does not necessarily mean that they are no good, it might be appropriate to re-enter in another round. The committees will motivate their choices and provide feedback.
  3. Prioritisation by the Roadmap Evaluation Committee – Meeting some months after the previous step Based on supplementary information requested in the previous step, the committee recommends which EoIs from categories A and B should enter the roadmap. The committee passes a list to the MAX IV board. Final decisions are taken by the MAX IV Board.

Evaluation criteria

The criteria and detailed evaluation process will be intensively discussed with the Swedish universities and user community. The evaluation criteria are expected to include issues that are fairly standard in these circumstances, for example:

  • Positions MAX IV at the international forefront of science
  • Utilizes the unique capabilities of MAX IV
  • Relevance to the current and future MAX IV user community
  • Potential for societal impact
  • Likelihood of success
  • Time needed to implement

When the detailed instructions for the evaluators have been decided upon, they will be published on this page.

What happens once you are in the Roadmap document?

There is no predetermined path to funding for roadmap items. MAX IV management will be responsible for reaching out to proposers and work towards possible avenues for funding. It is expected that proposers contribute to this fundraising, with the help of the designated spokespersons and in close collaboration with MAX IV.
