A limited MAX IV call for proposals is open for the BioMAX and NanoMAX beamlines serving the research areas of “Structural Biology” and “Nano Science” respectively.

Practical guidelines related to the User access and the use of MAX IV for research are presented here and grouped in three stages or parts of the whole process: the proposal, the beamtime and the reporting and feedback after beamtime:


1. Plan and submit your PROPOSAL

Here you find information useful for the preparation of the experimental project (proposal) for which you need the use of MAX IV: proposal types, calls and deadlines, research areas, beamlines, who to contact, how to submit a proposal to apply for beamtime, comments on the evaluation of proposals and which are the financial support options.

Types of Proposals and call periods

MAX IV will offer different modalities, or Proposal Types, to access the facility which will be adapted to the different user community needs. The call details for each access modality and the corresponding application period will be updated in Open Calls.
Currently, for this very first call, only the Normal proposal will be eligible to apply for beamtime. Normal proposal refers to projects submitted to apply for beamtime in the next beamtime allocation period.

Beamlines and science areas

The current MAX IV portfolio of beamlines covers the general techniques of spectroscopy, scattering/diffraction and imaging. Information on the individual beamline-specific techniques and other important details such as beam size, energy range, time scales, sample environments, detectors, etc. can be found on the corresponding beamline page.Each beamline will be associated with one or more specific science areas. This is important to know because every proposal has to select the one research area where it best fits in. The scientific evaluation of the proposal will be done by the committee associated to that particular science area.
Two science areas have been defined so far. These areas cover the scientific fields relevant for the two beamlines open at this first call for proposals:

  • Structural Biology for beamtime at the BioMAX beamline.
  • Nano science for beamtime at the NanoMAX beamline.


More science areas will be announced as further beamlines and methods become available.

Your Local Contact

Your Local Contact will be a staff member familiar with the beamline and instrumental set-up. He or she will make possible to perform your experiment. In some situations the experiment outcome could be enriched with the Local Contact effort beyond his/her normal duties. We encourage you to discuss such possibility before the experiment starts and, if appropriate, collaborative work should be agreed with the corresponding beamline manager.

How to apply for beamtime

All the applications for time to perform your experiment at MAX IV are handled by the MAX IV Digital User Office (DUO) interface. DUO was original developed at PSI and already used at MAX IV to handle the user access to MAX II and MAX III. In 2016, a new DUO upgrade has been adapted to the new MAX IV facility and user operation service. All the existent user accounts and previous proposal had been migrated to the new DUO system.

  • A proposal is submitted by the main proposer who is responsible for this proposal. All information from the DUO and the MAX IV laboratory is sent to the main proposer who is responsible for distributing this information to the co-proposers.


  • All users must have a user account in DUO. As some of the steps involved in the creation of a new account may take some time, it is strongly suggested to register well in advance of the proposal deadline. The user account is necessary to either be involved in the proposal as co-proposers or to apply for a badge to access the MAX IV site.


  • In DUO is possible and recommended to link previous experiments at MAX IV with a new proposal, if the new project is a continuation of a previous one. Previous experimental reports will be of importance in the proposal evaluation process, however, for the current call, after one year of commissioning of the new MAX IV facility: machine and beamlines, the previous experimental reports are not compulsory, but you are most welcome to upload them in DUO if you find it appropriate. It is also a good practice to upload your MAX IV publications in the DUO system, (see “3. …after your experiment”)


  • The sample declaration is an important part of the proposal. It is mandatory to declare all the samples as well as the use of additional chemicals. The step 4 of the proposal submission contains all the sample specifications and various safety issues to be declared for each sample. It is also required to provide updated sample information that might become available after the proposal submission and up to a month before the scheduled beamtime.


The DUO interface contains menus and explanations through its different pages. Further details and other tips on the DUO interface and submission guidelines, including FAQs, are collected here. The file will be updated as need it.

Evaluation of proposals

Proposals are evaluated by the Program Advisory Committee (PAC) and the final decision on beamtime allocation is taken by the MAX IV Laboratory.
The scientific merit, the proposal feasibility and the technical safety check of the proposed experiment will be the guiding criteria for awarding beamtime. Previous experimental reports will be of importance in the proposal evaluation process. Exceptionally, this will not apply for the very first call to each new MAX IV beamlines.

After the proposal review process is finished, the main proposer will be informed by the user office on the result. Users can also see in DUO the status of all their proposals.
If your proposal has been approved, you will be contacted by the corresponding beamline manager to schedule your beamtime.

Funding Access Programs

From March 2017 there will be funding available from iNEXT for experiments at MAX IV for EU-transnational users. Among the three major access themes offered through iNEXT, the one relevant to MAX IV users is: High-End Data Collection for protein crystallography. The iNext support at MAX IV covers the travel and accommodation expenses.
Proposals to iNEXT can be submitted at any time.
More information and the application for iNEXT support is done through the iNEXT proposal system.

It’s our pleasure to announce that we have been invited to grant preparation for the project CALIPSOplus!
Provided that the grant agreement between the EU Commission and the consortium will be signed as expected,
this implies that funding for transnational access to accelerator-based light sources in Europe will be available as of summer 2017.

2. Prepare for your BEAMTIME

Here you will find information relevant once your proposal has been approved, i.e. you have been granted beamtime. The main proposer will be informed by the user office and soon contacted by the corresponding beamline manager to schedule the beamtime. Users can also see in DUO the status of all their proposals.In addition to organizing the travel to Lund and booking their accommodation, there are a few more procedures to follow in preparation for the beamtime such as apply for your access badge and perform the safety tests.

Further practicalities during your beamtime at MAX IV and other useful tips during your stay in Lund will be updated here in due time.

3. Share and contribute after your experiment

A necessary stage of the “non-proprietary” access to MAX IV is to contribute with the outcome of your beamtime. This refers mainly to the publication of your results but also to the submission of the experiment report and visits feedback. All of the three different types of contributions should be provided through the DUO interface:

  • Visits/Feedbacks:
    The corresponding page allows you to provide feedback on your visit at MAX IV. It is more like a technical feedback rather than a scientific feedback. Every user who had been involved in any experimental session is kindly welcome to submit his/hers own feedback after each one of his/hers experimental sessions.
  • Experimental Reports:
    The experimental report on a proposal can only be entered by the main proposer or by one of the co-proposers. An experimental report template is available from the DUO interface. Any new upload associated to the same proposal will replace a report previously uploaded for the same proposal.It is convenient to upload the experimental report, with results from previous proposal, before a new proposal submission deadline. This applies if the experiments of the previous projects were completed more than two weeks before the new proposal submission deadline. The experimental reports will be of importance in the evaluation of the new submitted proposals.
  • Publications:
    We encourage users to register in DUO all new publications resulted from their beamtime at MAX IV.
