NanoMAX optics layout

NanoMAX is a Hard X-ray monochromatic nanoprobe experimental station at MAX IV, set for best performance between 7 and 30 keV.

After the pink photon beam is generated at the Undulator, the X-ray beam is cut by a set of slits to define the angular aperture. Then, a set of two mirrors focus the beam first vertically and after horizontally to the position of the secondary source aperture (SSA), 25.2 m upstream from the center of the last focusing mirror. In between, a horizontal Bragg diffracting crystal Si (111) monochromator is used to reduce the bandwidth of the X-ray beam and select the working energy in between 7-30 keV.

At the SSA position, the beam is cut to maximized the coherence part of the beam and generate a new virtual source that will be used at the experimental end stations as coherence source.
