Mk 1 Mod 0 Squibs were fired in the wave guide of a 9kmc radar. For fully loaded squibs, on the basis of previous tests at dc to 5 megacycles, the bridgewire in the 9kmc tests did not reach the temperature expected necessary for firing. Squibs without cup or base chargeAPPROXIMATED THE EXPECTED FIRING TEMPERATURE. From the results it is inferred that squib simulators used to predict firing on the basis of bridgewire temperature may not be applicable at frequencies as high as 9kmc. It is also hypothesized that the powder charges in some devices may act as attenuators somewhat reducing the probability of f ring in high frequency rf fields.
