Calibration of the Rapid Scan Particle Detector Mounted in the SCATHA Satellite.
Abstract
A rapid scan particle detector (RSPD) for electrons and protons in the range of 0.05 keV to greater than a few MeV has been designed, constructed, and calibrated. The RSPD uses electrostatic analyzers (ESA's) with Spiraltron electron multipliers (SEM's) for 0.05 to 60 keV particles, and solid-state detector telescopes for the higher energy particles. The ESA's have been extensively calibrated at the Rice University Calibration Facility, using 0.04 to 45 keV electrons and 0.1 to 30 keV ions, and the results are given in this report. The calibration procedure for the SSS's is also described, and the results are tabulated. The RSPD was launched in the SCATHA satellite on 30 January 1979 and is known as the SC5 instrument. Orbit operations have been excellent, with the SSS's operating nearly 100 percent of the time and the ESA's operating about 50 percent time operation at a higher bias level is achieving a sufficiently stable operation that should allow reliable data-taking for at least the one year- design lifetime.
