Prototype Instrumentation and Design Studies
Abstract
The Shuttle Potential and Return Electron Experiment (SPREE) was flown as part of the Tethered Satellite System (TSS-1) on STS-46 launched on July 31, 1992. A significant portion of this contract has been spent on the design and development of the SPREE analyzer system. The successful launch and operation of the SPREE during the TSS-1 and EOIM mission were the culmination of the past five years' work. This final report details the SPREE system as flown and some of the preliminary results. These successes include a real-time charging detection algorithm that correctly and accurately diagnosed the potential of the Shuttle with respect to the ambient plasma, a particle correlator system that was able to accurately detect and analyze wave/particle interactions triggered by electron beam operations, a pair of digital data recorders that archived 5 Gigabytes of data, two sets of triquadraspherical electrostatic analyzers that measured the flux of electrons and ions from 10 eV to 10 KeV and from 10000 to 1 x 10 to the 14th particles/sq cm-ster-sec., and occasional operating pressures that exceeded 0.0001 Torr....
