The SSJ3 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
