The results of irradiation tests are presented. The tests were performed using an experimental technique for transient effects measurements, which should eliminate the interfering effects of coaxial cables. The coaxial cable tests with the suggested technique reveal a cross-over voltage near zero for coaxial cables, which greatly simplifies transient effects measurements. These tests serve to prove the system out for a great number of transient radiation effects tests. Variations in the type of electrostatic shielding were tried on a two-watt carbon composition resistor, but these tests showed that electrostatic shielding may not be needed for many parts using the proposed experimental system, because the aluminum box used in this system for mounting the part already provides sufficient electrostatic shielding. Additional confirmation of the proposed experimental technique was obtained in the dc capacitor tests through the yielding of consistent results. Dose damage to the paper capacitors used was revealed, and the leakage conductivities calculated agree with the results of other investigators. Amplitude demodulation techniques were tried in the ac carrier method of measuring capacitance change in order to increase sensitivity, but the tests failed to produce reproducible results.
