Linear optocouplers are more affected by current drive conditions because the detector operates in a high-injection region when the LED produces normal light output, and do not have the extra operating margin that is inherent in digital optocouplers. Although LED degradation is often the dominant degradation mechanism in space environments, degradation of optocouplers with improved LEDs is limited by photoresponse degradation. Phototransistor gain has a relatively minor effect except at very high radiation levels.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.

The presence of relativistic electrons in the magnetosphere induces whistler wave excitation due to various kinds of instabilities, such as temperature anisotropy, loss cone or beam type instability. Such studies on whistler wave excitation induced by energetic particles in the magnetospheric plasma are generally carried out for nonrelativistic electrons (CRRES, ARAKS, ECHO, SEPAC, Spacelab missions...). In this paper, first results that we have obtained concerning the whistler mode excitation for parallel and oblique propagation, and for relativistic electrons, are presented both for temperature anisotropy and beam type instabilities. The theoretical formalism that we have used to derive the wave dispersion equation is first described.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.
