SoftiMAX is a soft X-ray beamline, dedicated to spectromicroscopy and coherent imaging. The beamline will operate in the photon energy range between 275 eV and 2.5 keV and have two branch lines: one for STXM and Ptychography with a sub-100 nm focus, and one modular line for coherent techniques that require a larger beam size.

SoftiMAX is funded through Vetenskapsrådet.

For the commissioning call opening September 17, 2020, proposals for the following operation modes will be welcomed. These milestones vary in technical complexity and will be scheduled accordingly.

N.B.: This call is open for expert users only.

First light at SoftiMAX

SoftiMAX is the 13th beamline to “see the light” at MAX IV. The team received approval mid-March from the Swedish Radiation Safety Authority to start commissioning and has made rapid progress since then. The synchrotron light was delivered all the way from the undulator to the monochromator within the first few hours after opening the shutter.
