A spark gap switch system is disclosed which is capable of operating at a high pulse rate comprising an insulated switch housing having a purging gas entrance port and a gas exit port, a pair of spaced apart electrodes each having one end thereof within the housing and defining a spark gap therebetween, an easily condensable and preferably low molecular weight insulating gas flowing through the switch housing from the housing, a heat exchanger/condenser for condensing the insulating gas after it exits from the housing, a pump for recirculating the condensed insulating gas as a liquid back to the housing, and a heater exchanger/evaporator to vaporize at least a portion of the condensed insulating gas back into a vapor prior to flowing the insulating gas back into the housing. |

DETAILED DESCRIPTION It is, therefore, an object of this invention to provide a spark gap switch system which uses an easily condensable gas as the insulating gas.
It is another object of this invention to provide a spark gap switch system which uses an easily condensable gas as the insulating gas which is also used for purging the hot gas residues from a high pulse rate spark gap.
It is yet another object of this invention to provide a spark gap switch system which uses, as the insulating gas, an easily condensable gas which, when it dissociates in the spark discharge, forms gaseous products which will not form solid residues on the walls of the spark gap switch housing.
It is a further object of this invention to provide a spark gap switch system which uses, as the insulating gas, a gas which is easily condensed at moderate temperatures, when it is used at a low pressure, to permit recycling of the insulating gas as a liquid back to a vaporizing station in the system.
It is a yet a further object of this invention to provide a spark gap switch system which uses, as the insulating gas, an easily condensable gas selected from the class consisting of steam, ammonia, and halocarbons having the formula C.

i where X is fluorine and/or chlorine, m is 1 or 2, n is 1 to 4 when m is 1 and from 1 to 6 when m is 2, and i is the number of hydrogen atoms not displaced by fluorine or chlorine; and mixtures thereof.
It is still another object of this invention to provide a spark gap switch system which uses, as the insulating gas, a low molecular weight gas which is easily condensed at a moderate temperature when it is used at a low pressure.
It is still a further object of this invention to provide a spark gap switch system which uses steam or ammonia vapor as the insulating gas.
These and other objects of the invention will be apparent from the following description and accompanying drawings.
