DEVELOPMENT OF A UNIVERSAL RADIO FREQUENCY PROTECTED SQUIB
Abstract
Experiments were conducted to determine if it is possible to attenuate RF energy in a transmission line by coupling the line to a transformer with a lossy core. This device was designed specifically to provide high core loss and eddy current loss. Tests over the frequency range from 20 kc to 1 Mc indicated that adequate RF protection could be provided for an electroexplosive device having a 1-ohm bridge wire. It was possible to fire Mk 1 mod 0 squibs through the transformers with a 2 millisecond pulse of 14 volts magnitude. Dissipative filters of various types showed promise. An analog computer is being used to evaluate these filters and gain information as to arrangements which would give as much RF attenuation as possible without unduly reducing the firing sensitivity of an electroexplosive device. The evaluation of solid state devices was continued, but only transistor switching circuits showed promise.
