ABSTRACT:
A spark channel purge system for high pulse repetition frequency spark gap switches. A purge fluid having a liquid state and a gaseous state is caused to flow through a spark gap channel, at least a portion of the purge fluid passing through the spark channel being in the gaseous state. The purge fluid is supplied in its liquid state by a purge fluid source. In some embodiments, the purge fluid source is a recirculating flow loop which includes a heat exchanger, while in another embodiment, the purge fluid source is a low-pressure liquid storage vessel. The heat exchanger transfers waste heat from the spark gap switch via the purge fluid flowing from the spark channel into the purge fluid supplied by the purge fluid source. This causes at least a portion of the liquid purge fluid to change to the gaseous state. In some embodiments, the spark channel purge system is suitable for a closed loop system, while other embodiments are suitable for an open loop system. In the two-phase flow loop embodiments, the two-phase purge fluid can be mixed to absorb energy from the spark gap switch.
