Abstract
Plasma switches are able to operate at a much higher energy density than traditional switched capacitor banks as well as handle much higher currents, and are particularly well suited for pulsed power applications. A present limitation on the implementation of open plasma switches into related technologies is the relatively short lifespan and low operational frequency at which these devices must operate. To overcome this limitation we are going to use our experience in development of plasma switches that are able to form short (rise time 5-100 ns) high voltage (15-100 kV) pulses with current up to several kilo amperes and with a repetition frequency up to several kilo hertz, and to develop a method for splitting high impulse current into many channels with spark gaps. Each spark gap will have separate storage capacitance and charging circuit with controlled and adjustable charging current. Output cathodes of all spark gaps will be connected with the same load and all channel currents will be summarized by synchronizing of the spark gaps ignition. If successful, we will develop an advanced plasma switch consisted of multiple spark gaps that will be suitable for high currents and fast rise time capabilities.
