AIR SCINTILLATION DETECTOR FOR CONVERSION ELECTRONS MOSSBAUER-SPECTROSCOPY (CEMS)

A detector for low-energy conversion and Auger electrons used for CEMS are described. It is based on the registration of light pulses produc ed by microdischarges in rare air caused by electrons under the presen ce of an electric field. The main parameters of the proposed Air Scint illation Detector (ASD) are comparable with parameters of usual CEMS d etectors. However, the contrary to standard detectors, the ASD allows to investigate samples of almost arbitrary shape and size. It extends the field of CEMS applications, in particular, for investigation of tr ibological problems.
