Variations in the electrostatic response of circuit boards with x-ray bremsstrahlung spectra

Conference · · Transactions of the American Nuclear Society; (USA)
OSTI ID:5233400

Electronics, exposed to the prompt radiation of a nuclear event, experience not only transient radiation effects in electronics (TREE) from dose deposited in devices but also current injected into the device from photoelectrons, which couple into the circuit lands on the printed circuit boards, an effect referred to as box internal electromagnetic pulse (IEMP). Laboratory pulsed radiation machines employ electron bremsstrahlung to generate their spectra. For such machines, the dose deposited over a circuit board increases approximately as the cube of the diode voltage. To achieve a higher dose, it is desirable to increase the diode voltage. To test a piece of electronics, it is desirable to generate both the IEMP and TREE responses. This paper illustrates the variation of the box IEMP with bremsstrahlung diode power-weighted-mean diode voltage and discusses the causes of the variation.
