Prototype Instrumentation and Design Studies

Abstract : Flight prototype sensor systems using spherical sections and electro static deflection are being developed, fabricated, tested and calibrated. The detectors will measure the flux of ions and electrons over a 100 deg x 10 deg angular fan and in 32 discrete energy levels from 10 eV to keV. This report describes the sensor system design for an instrument package for shuttle flight as well as a correlator to look for wave-particle interactions.
