This project was conducted to obtain data on the transient response of typical ballistic missile guidance and control systems to the prompt gamma pulse from a nuclear weapon. Self-reading instrumentation was installed at four stations corresponding to four decades of gamma radiation intensity to determine whether the output transients in these circuits exceeded present threshold levels during the test. Additional diagnostic instrumentation was provided at one location to obtain pulse shape information on the circuits, gamma dose rate time history, and analog data on circuits which exhibited long recovery times. Extensive pre- and post-shot laboratory experiments were performed to determine response in an actual weapon environment. Results indicated that field test data are consistent with the combined experimental and theoretical predictions.
