Abstract:

Research is concerned with developing an electroexplosive device EED which will be protected against accidental initiation by radio frequency energy. The latest state-of-the-art techniques will be applied with the objective of minimizing the RF hazard size and firing characteristics of the EED being of secondary consideration. Various types of filters have been studied to determine their ability to attenuate RF signals at frequencies above 20 kilocycles per second. One of these filters promises to supply at least 30 db insertion loss from 20 Kc to 500 Kc. Others promise adequate attenuation at frequencies above 10 Mc. Two solid state devices have been investigated a dissipative capacitor and a transistor switch. The dissipative capacitor will require further development before we can determine its worth as a protective device. The transistor switch provides adequate protection but requires a more complicated firing circuit than normally used. Author
