The SoftiMAX beamline will provide soft x-ray imaging techniques built around the use of spatially coherent light waves. These techniques produce microscopic images of a sample, which at the same time can hold chemical, electronic, magnetic and/or structural information, depending on the details of the experiment.
The beamline will have two branchlines: one for scanning transmission microscopy (STXM) & ptychography where thin samples (eg., 0.1 - 5 micron) are raster scanned with a nanobeam focused through a zone plate lens. This branch will be completed first.
The second branch line will be dedicated to Coherent X-ray Imaging (CXI) techniques, where the end station will have a more modular character. Several techniques such as coherent diffraction imaging, holography and resonant soft x-ray scattering are foreseen here.

Heavy milestone in place for SoftiMAX
At the beamline SoftiMAX, users will have access to methods for X-ray imaging and microscopy for investigation of everything from cells and viruses to how pollutants move through an ecosystem. An important step in the construction process for the beamline was taken recently when the fourteen tonnes insertion device, an instrument holding an array
