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 beamline components for the beam shaping and beam transport up to either of the two experimental stations are described in detail in: Johansson et al. 2021.

The focusing optics for creating the nano-focused X-ray beam at the experimental stations are described on the respective pages.
