Infrared Coordinate Detector for the Measurement of Angular Divergence in Synchrotron Radiation

The multi-channel detector system for measuring angular distribution of the synchrotron radiation intensity in compressor of electron rings of JINR is described. The detector consists of uncooled photoresistors made of PbSe with 120 mm long linear arrangement of elements with 0.2×1 mm area. The system is intended for measuring the absolute number of electrons and for investigation dynamics of electron (electron-ion) ring-shaped bunch.
