Design, Develop, Fabricate, Test and Deliver a Protoflight Medium-to-High EnergyElectron Detector for Integration into a Small On-board Diagnostic Sensors Package

摘要

An electron spectrometer is being designed to measure electron flux in the rangeof 3 to 30 MeV. A breadboard unit has been designed and tested, using a solid state detector telescope for geometric factor definition and a Cerenkov radiator/PMT for energy measurement. The measured response to electrons is very broad, so the Cerenkov radiator is being redesigned as a larger volume with larger PMTs to improve the energy resolution. Following testing of the modified Cerenkov radiator/PMT, a protoflight unit will be fabricated, tested and calibrated. The protoflight electron spectrometer is to be integrated to the Small Onboard Environmental Diagnostic Sensors (SOBEDS) Package.
