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. Only the first branch is available at this time.

Proposal call for HT2022

The next proposal call will open between February 14, 2022 and March 14, 2022 at 23:59 CET, and cover the beamtime period August 2022 to February 2023. SoftiMAX is not fully commissioned, yet, but we are offering additional techniques to general users during this call, as well as commissioning beamtime for the high end of the energy range:

Available forTechnique description
General UsersSTXM at absorption edges between photon energies 275 eV and 1600 eV, with spatial resolution between 22-60 nm, depending on energy range and sample properties.
General UsersPtychography at absorption edges between photon energies 700 eV and 1600 eV, with illumination spot size between 22-60 nm in focus, depending on energy range and sample properties. The Andor Zyla detector is availabe in this call.
General UsersCircularly polarized x-rays in both helicities are available in addition to the default linear horizontal polarization in STXM and Ptychography modes. Restrictions apply; Please contact beamline staff if you intend to use circular polarization.
Commissioning UsersSTXM, Ptychography and X-ray Fluorescence imaging (XRF) at absorption edges between 1.6-2.5 keV, with illumination spot size of about 60 nm (resolution limit in STXM and XRF modes).

Proposals must be submitted via the MAX IV DUO system, however, we strongly encourage interested users to contact the beamline staff to discuss their experiments prior to submission.

SoftiMAX is funded through Vetenskapsrådet.
