Instrumentation for soft X-ray emission spectroscopy

An account is presented of developments in instrumentation for soft X-ray emission spectroscopy (SXES) based on synchrotron radiation. An account for grating spectrometers for soft X-ray emission spectroscopy is given, and some considerations regarding synchrotron radiation applications of the spectroscopy are presented. A few points that relate to the new features of resonant SXES and polarization dependent studies are discussed in some detail. A brief discussion on future developments in SXES instrumentation is included.
