Abstract In this paper, we present a soft x-ray variable line-spacing spherical grating monochromator, which is shared between the three ATHOS beamlines at SwissFEL. The instrument uses grazing incidence angles of less than 3° to withstand peak-fluence femtosecond FEL pulses with energies up 8 mJ. upward facing monochromator facilitates endstations different beam heights. We explain integration...

The 3 m toroidal grating monochromator (TGM) VUV beamline at CAMD/LSU was realigned to achieve better illumination of the monochromator gratings with the goal of substantially increasing the fl ux at the higher photon energies. This is partly accomplished through a tilting of the monochromator (by about of 13.5°), with respect to the plane defi ned by the synchrotron, providing a smaller grazin...

We present the x-ray optical design of the soft x-ray materials science instrument at the Linac Coherent Light Source, consisting of a varied line-spaced grating monochromator and Kirkpatrick-Baez refocusing optics. Results from the commissioning of the monochromator are shown. A resolving power of 3000 was achieved, which is within a factor of two of the design goal.
