NanoMAX is a Hard X-ray monochromatic nanoprobe experimental station at MAX IV, set for best performance between 8 and 15 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 5-28 keV.
At the SSA position the beam is cut to select the coherent part of the beam, generating a new virtual source for the experimental stations.
The optical components of the beamline are described in detail in: Johansson et al. 2021.
The optics for creating the nano-focused X-ray beam at the experimental stations are described on the respective pages.
