ABSTRACT:
Method and apparatus for switching high power at high repetition rates. The apparatus is preferably a switch utilizing a pressurized flowing dielectric. The pressurized dielectric suppresses growth of dielectric breakdown byproducts, such as large bubbles and breakdown contamination, enabling lower dielectric flow rates to remove the byproducts. In addition to the advantage of lower flow rates, and thus smaller and lighter pumping means, the switch can switch high energies (up to megajoules) at fast repetition rates, up to thousands of pulses per second.
