摘要： An over-voltage protection system for an accelerator can include: a plurality of DC power supplies configured to provide a plurality of voltage levels up to a desired voltage level; and an acceleration tube electrically connected to the plurality of DC power supplies and configured to accelerate a charged particle. The acceleration tube can include a plurality of stages. Each stage can include a plurality of electrodes and a plurality of varistors configured to discharge energy in response to an overvoltage event. One electrode of the plurality of electrodes can be electrically coupled to a voltage level of the plurality of voltage levels. The plurality of electrodes and the plurality of varistors can be electrically coupled to each other and arranged in an alternating fashion.
