ResumoA 24-m spherical grating monochromator designed for operation in the VUV region at the Photon Factory is described. With two in situ interchangeable gratings the instrument covers the spectral range of 44 to 410 Å (280 to 30 eV). The beamline optical system consists of a 1 : 1 prefocussing toroidal mirror, a spherical grating monochromator with a movable exit slit, and refocussing mirrors. The photon flux, resolution and higher-order contributions are reported as determined by test measurements at the experimental station.
