ANALYSIS OF RADIATION EFFECTS IN TELEMETRY CIRCUITS

Abstract

The effects of nuclear radiation on the telemetry circuits in the LES satellites have been analysed by direct irradiation and by simulating the effects on individual components on a breadboarded circuit. The simulation method is described in detail. It requires a precise knowledge of the behavior of each component operating under specified bias conditions in a radiation environment, but may be applied to circuits of considerable complexity. The analysis confirmed that circuits such as the flip-flop, which operate at 50 per cent duty cycle, are insensitive to moderate leakage currents and have low gain requirements, are extremely radiation resistant. The converse holds for circuits that operate at low duty cycles, that are sensitive to leakage currents and that have more stringent gain requirements.
