This paper was prepared for submission to the Thirteenth Pulse Power Symposium in Buffalo, NY, June 19-22, 1978. Stapled at upper left corner. Results were to be presented on the design and testing of a pressurized gas blown spark gap switch capable of high repetition rates in a burst mode of operation. The switch parameters which had been achieved were as follows: 220-KV, 42-kA, a five pulse burst at 1-kHz, 12-ns risetime, 2-ns jitter at a pulse width of 50-ns. The construction of the coaxial spark gap is illustrated in Figure 1. The spark gap bolts on to the lower end of a 5.2 coaxial water Blumlein and was designed to switch the mid conductor to ground. The Blumlein's mid conductor feeds through a polycarbonate resin insulator which interfaced between the water and the high pressure gas and become the switch's anode. From Wikipedia: A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the potential difference between the conductors exceeds the breakdown voltage of the gas within the gap, a spark forms, ionizing the gas and drastically reducing its electrical resistance. An electric current then flows until the path of ionized gas is broken or the current reduces below a minimum value called the "holding current". This usually happens when the voltage drops, but in some cases occurs when the heated gas rises, stretching out and then breaking the filament of ionized gas. Usually, the action of ionizing the gas is violent and disruptive, often leading to sound (ranging from a snap for a spark plug to thunder for a lightning discharge), light and heat.
