Abstract:

COMPUTER PROGRAM, SCEPTRE COMPUTER PROGRAM, UNIVAC 1108 COMPUTERS, COMPUTERS, GRAPHICS, COMPUTERIZED SIMULATION Radiation effects analysis of complex electronic circuits by computers presently is limited by core storage and long execution times. A new method, entitled Iterated Propagation of Bivariable Response Functions, treats components in the block sense using experimentally obtained time domain response or transfer functions. These functions are described in a three dimensional space of the input stimuli, output response, and time, by means of fitting the experimental data with cubic polynomials matched in the spline sense at interstices of the fitting grid. The basic data was obtained using conventional oscilloscopic techniques at the Kirtland AFB, flash X-ray facility and the Sandia pulse reactor. A UNIVAC 1108 computer program called SAP, adapted to work with SCEPTRE, uses a modified convolution process to calculate the electrical and the gamma and neutron radiation responses from the surface descriptions.
