Rocket Measurement of the Energy Distribution and Flux of Thermospheric Photoelectrons.
Abstract
An electron analyzer of the 127 deg cylindrical electrostatic deflection type, designed to measure the energy distribution and flux of thermospheric photo-electrons in the energy range from near zero to 100 eV, has been successfully flown on a rocket probe. The design and operational characteristics of the instrument are briefly described and the importance of full calibration procedures discussed. Methods for correcting or minimizing the effects of vehicle-induced disturbance of the environment being measured were incorporated into the experiment. These included correction for the energy attenuation and refractive signal losses which are the dual effects of vehicle skin charge. Photoelectron spectra in the energy range 2 to 100 eV were measured over an altitude range of 100 to 220 km during the first flight of the instrument.
