IRRADIATION TESTING OF OPERATING ELECTRONIC EQUIPMENT BY FAST NEUTRONS AND GAMMAS. Final Report
A study of the radiation effects of fast neutrons (O.5 ev to about 15 Mev) and gamma rays (fission spectrum) on various pieces of aircraft instrumentation is re ported. Components studied were: fuel gage vacuumtube amplifier and indicator, transistorized (germanium and silicon) servo amplifier system, and 4-in. diam. gyro. The fuel gage was subjected to a total neutron flux of about 6 x 1O/sup 5/nvt and about 5 x 1Osup 8/ r gamma with no adverse electrical effect. Physical damage was evident. Four transistorized amplifiers were irradiated in a fast flux of about 1.0 x 10/sup 10/cm/sup 2/ sec. Rapid loss in gain, rapid increase in d-c current drain, and complete failure occurred when the integrated flux reached about same flux. Studies on the gyro were inconclusive due to equipment failure. (auth)
