Shuttle Potential and Return Electron Experiment (SPREE) Electrostatic Analyzer (ESA) Calibration Report.
Abstract
A pair of 260 deg, spherical-plate electrostatic analyzer (ESA) units were designed, built and flown as part of the Shuttle Potential and Return Electron Experiment (SPREE) onboard the Tethered Satellite System 1 (TSS-1). Each ESA simultaneously measured ions and electrons in the energy range of 10 eV to 10 keV over an angular fan of 100 deg by 10 deg. The deflection voltage of the ESAs was logarithmically stepped through 32 channels at a rate of either 8 (fast mode) or 1 slow mode) sweeps/second. The geometric factors for the two units differed by 2 orders of magnitude so that both ambient and perturbed plasma conditions could be measured during the TSS-1 mission. In this report we present the results of the detailed calibration of these ESAs.
