The first commissioning expert user call for STXM and Ptychography experiments will open on September 17th 2020 with deadline on October 13th.

Commissioning call for proposals

Commissioning of the beamline started in early 2020 and the beamline saw first light on March 17. During the autumn of 2020, the beamline will be first opened to commissioning proposals, whilst we continue installations and testing.

The photon energy available at SoftiMAX will be 275 eV to 2.5 keV, however, we will begin with commissioning experiments between 400 eV and 1.6 keV. Likewise, we will start our commissioning with the PMT detector only. Extension to the full energy range, and the use of the different detectors, are some of the milestones we wish to achieve during this commissioning call.

Expertise and experience relevant to commissioning the following capabilities on SoftiMAXare welcomed:

  • STXM with reduced photon energy range; extending to carbon K-edge; going up to 2.5 keV; and using circularly polarised light
  • Ptychography, commissioning two different detectors
  • Fluorescence, either with scanning photon energy or fixed high photon energy
  • Exploring the boundaries of SoftiMAX with regard to spatial resolution and coherence properties
  • Sample environments, using either the SoftiMAX heating/electro-chemistry cell or user-provided holder


With the exception of the sample environment commissioning, we envision users to bring ready-made samples fixated on SiN membranes or TEM grids. Currently, the spot size at the sample is 50 nm, but other zone plate options will become available as commissioning progresses.

Commissioning users are also expected to have experience in the relevant data analysis.

Proposals must be submitted via the MAX IV DUO system, however, we encourage interested users to contact the beamline staff to discuss commissioning experiments. When submitting proposals in DUO, please choose ‘Commissioning’ as a research area in order to select SoftiMAX.


When publishing any material arising from work carried out at MAX IV, do not forget to acknowledge MAX IV and our funders. This obligation applies to both infrastructure personnel and researchers using the infrastructure.
