Design of soft x-ray plane-grating monochromator for CAMD

Abstract

A plane-grating monochromator (PGM), the CAMD-PGM, designed for bending magnet radiation is described. In contrast with many other similar PGMs, the CAMD-PGM is equipped with an entrance slit. The wavelength range of 6–1500 Å is covered with two gratings (1220 and 360 gr/mm). The expected performance is a resolving power, λ/Δλ, of ∼2000 with the photon flux of ∼ 1010 photons/s at the photon wavelength of 10.0 Å. The beam spot size at the sample position is approximately 1×1 mm2. The monochromator is being constructed and will be installed in the summer of 1992.
