✦ Synopsis

A toroidal grating monochromator designed for operation in the soft X-ray region at the synchrotron radiation source BESSY is described. With three in situ interchangeable gratings the instrument covers the spectral range 180 to 1150 eV. The current (source size-limited) resolution is 0.39, 0.7 and 2.6 eV at photon energies of 250, 400 and 800 eV, respectively . The photon flux is typically 8 x 10" photons s-1 (100 mA)-1 (dhto) -1 . Photoemission experiments on free molecules and on solid surfaces have been used to demonstrate the performance of the monochromator.
