THE EFFECTS OF REACTOR RADIATION ON THE ELECTRICAL PROPERTIES OF ELECTRONIC COMPONENTS. PART VII. RESISTORS AND VACUUM TUBES
Several types of vacuum tubes and resistors were irradiated with the Ground Test Reactor for a period of 100 hours at a power level of 1 megawatt. Data were taken on the components before, during, and after the irradiation. The vacuum tubes received a maximum radiation exposure of 8.64 x 10/sup 1//sup 5/ nf/ cm/sup 2/ and 3.9 x 10/sup 1//sup 0/ ergs/gm(C). A small increase in the average plate current was noted for all tube types. Pentodes subjected to the high-flunx field exhibited the largest percent change ( approx equal 6%) while dicdes remained relatively unaffected-at these radiation levels. The resistors received a maximum radiation exposure of 1.4 x 10/sup 1//sup 6/ nf/cm/sup 2/ and 6.2 x 10/ sup 1//sup 0/ ergs/gm(C). The degree of damage was dependent upon the material and type of construetion of the individual resistor types. The maximum observed change ( approx equal 6%) occurred in fixed-composition resistors.
