TRANSIENT RADIATION EFFECTS ON BASIC TRIODE AMPLIFIERS.
Abstract
Transient radiation-effects data on basic triode amplifiers were obtained for gamma radiation exposure rates varying from 1 x 100000 to 1 x 10 to the 7th power r-sec(1-). The net effect of the interaction of nuclear radiation with the basic amplifiers is equivalent to introducing a current generator into the grid circuit. For a potted amplifier using a 12AX7 miniature tube with a plate potential of 250 v, this current is on the order of 5 to 8 x 10 to the minus 13th power amp-sec-r(1-). The neutron radiation, which accompanies the gamma radiation in a reactor, did not have any appreciable effect. The radiation facility and experimental techniques are discussed. Data are also given on leakage currents in the potting compound, glass envelope of the tube, mica spacers, and air. (Author)
