Abstract
Disclosed is a surge protection system for use with an ion source assembly. The system comprises a high voltage power source coupled in series with a thermionic diode and an ion source assembly. The high voltage power supply is enclosed in the pressure tank and drives the ion source assembly. The thermionic diode is comprised of an insulating tube disposed between the ion source assembly enclosure and the output of the high voltage power supply and makes use of existing ion source assembly components to limit damage to the power supply during arc failures of the ion source assembly.
