Abstract:

The measured response of typical circuit cards and simplified circuit cards to ionizing radiation is examined. As in previous tests, the response to the gama rays is found to be reasonably well understood. The anomalous response to x rays is again observed during and after biasing. For the simplified card, these anomalies are reasonably well understood however, this is not true for cards with more complex geometries. Methods for understanding the response of the more complex cards are discussed. Keywords Circuit Card Gamma Ray Radiation Effects and X rays.
