Picatinny Test No. 2. The apparatus consists of a fixed gap electrode which. uses steel needles. The discharge circuit is similar to that of the Picatinny Test No 1, using the gap length of 0.005 inch set with a feeler gauge. In nearly very respect, this test is inferior to the test No 1. It has been used for distinguishing primaries from hoosters (Ref 35, p 27)... 

For small U and C values, the discharge resistor may be permanently connected to the capacitor. In the example given above, the resulting power loss would be 10 kW. Consequently, a discharge switch shall be fitted which automatically closes the discharge circuit. For pressurized apparatus, a single-pole vacuum tube (contactor type) may be used. Its open position is achieved by a pneumatically actuated drive, the closed position should be maintained by the atmospheric air pressure, and, if necessary, by an additional helical spring.

Kirshenbaum [8] demonstrated that the initiation probability ofRD1333 lead azide by gaseous discharge is a strong function of the properties of the discharge circuit, particularly as they affect the rate of the energy delivered to the spark gap. Two series of tests were conducted with a fixed-gap, parallel-plane apparatus.

Moreover, the hysteresis characteristics of the multi-stacked actuator was investigated to compare the performances of the PWM-PID control and continuous PID control, as shown in Fig. 7.29. The hysteresis of the multi-stacked actuator driven by the PWM-PID controller is smaller than that driven by the continuous PID controller. This can be explained by the discharging circuit of the high-voltage switching circuit. 

A device consisting of 15 vol% nickel powder and 40 vol% SiC powder dispersed in a silicone resin binder has been fabricated. Thermal curing is performed via a peroxide initiator. The resulting device switches from a high resistance state (>10 Q) to a conductive state (1-10 Q) when subjected to electrostatic discharge circuit transients. This response effectively shunts transients to ground in times of <25 ns [22].
