TRIGGERING MECHANISM OF LOW-PRESSURE SPARK GAPS
The triggering delay in two low-pressure spark-gap switches, operating in the pressure range 10/sup -3/ to 3 x 10/sup -2/ mm Hg, was measured under a wide range of conditions, When the trigger pin is in the negative electrode, the delay is found to consist of two components. The first part depends on the construction of the trigger pin, the trigger voltage, and the impedance of the trigger circuit, while the second part depends on the nature and pressure of the gas in the gap, and the voltage and impedance of the circuit being switched. If the trigger pin is in the positive electrode a further delay is added which is approximately equal to the transit time of an ion across the gap. A mechanism for the breakdown is proposed which is consistent with the measurements and with previously reported results. (auth)
