PROTEL: Design, Fabrication, Calibration, Testing, and Satellite Integration of a Proton Telescope
Abstract
A high energy proton telescope, PROTEL, was designed, fabricated, calibrated, tested, and integrated as part of the SPACERAD experiment for the Combined Release and Radiation Effects Satellite (CRRES) payload. As designed, PROTEL measure the differential energy spectrum of protons in 24 channels logarithmically spaced from 1 to 100 MeV, and the approximate flux of heavy ions. It consists of a Data Processing Unit (DPU), and two sensor head assemblies (High and Low Energy Head). The active elements of the sensor heads are stacked arrays of silicon-lithium drifted and surface barrier solid state detectors. This report describes the basic design, the command system, and the telemetry format of PROTEL, as well as the test and calibration results for the detector head assemblies, and electronic logic system obtained with several accelerators. Also described are results of computer modeling of the responses of the instrument, particularly the estimation of pulse pileup and efficiency. Keywords: Radiation belts; Proton environment; Particle detectors(Solid state).
