Calibration of the SSJ/3 Sensor on the DMSP Satellites.
Abstract
The SSJ/3 sensor is designed to measure electrons from 50 eV to 20 keV. This is accomplished by using two head assemblies with common signal processing and voltage sources. The low-energy head assembly selects 50.0 to 1,000 eV electrons over eight channels with a normalization factor H = 0.000043 sq cm- ster. The high-energy assembly similarly selects 1.00 to 20.0 keV electrons over eight channels with an H-factor equal to 0.000013 sq cm-ster. Energy resolution is approximately 10% for an isotropic incident flux. An electron beam was used to determine angular and energy response. These measurements were compared with results from a Monte-Carlo computer code and approximate analytic methods to determine the final normalizations. (Author)
