Computer and laboratory modeling of a radiation-acoustic detector for charged particle pulse beams and plasma parameters measurement

Summary form only given, as follows. Model investigations and laboratory tests of detectors for charged particles pulse beams and plasma parameters measuring are presented. The detector represents a combination of classic Faraday cup with an electrical method of obtaining a signal and a radiation-acoustic meter of pulse beam parameters. The radiation-acoustic meter consists of two parts-a thin detector, transparent for beams of high energy particles, and a thick detector with full absorption. Ultrasonic oscillations, which arise during interaction of charged particle pulse beams or plasma with detector material, are transformed by a piezoelectric detector into electric signals, whose amplitude-frequency and time characteristics functionally depended on the beams parameters. All the signals come into a microcontroller device Intel MSC51. This device produces calculations of the following beam parameters: average energy, pulse charge, pulse currents, density, beam size and pulse time.
