TRANSIENT RADIATION EFFECTS ON PASSIVE PARTS.
Abstract
Test covered the following areas of investi gation: (1) Coaxial cable tests; (2) Resistor tests; (3) d.c. capacitor tests; and (4) a.c. capacitor tests. Discrepancies with previous tests were observed in the coaxial cable tests. These were greater fluctuations in responses and apparently increased crossover voltage which were attributed chiefly to the physical condition of the cables and to their previous history of radiation and voltage. The resistor tests revealed only the effects of the cables and demonstrate that the internal effects on resistors are exceedingly small as to be expected on the basis of their internal capacitance. The d.c. capacitor tests demonstrate the usefulness of the system for measurements on capaacitors. Leakage resistances in 0.01 microfarad capaci tors are found to be 10 megohms in ceramic disc types, 1.2 megohms in Vitamin Q types, and 0.8 megohms in oil-paper type. The a.c. capacitor tests continue to be plagued withh problems. The results are at variance with calibration curves. The system will be examined in detail and laboratory calibration procedures improved before further irradiation tests are undertaken. (Author)
