The bipolar kicker power supply principle prototype for the booster ring of HIAF

BackgroundThe kicker power supply is one of the key devices to achieve fast extraction for the booster ring (BRing) of high intensity heavy ion accelerator facility. For the expected high beam intensity in the BRing, a beam dump is requested for an emergency case. Therefore, a bipolar kicker power supply is required to extract bunched beams to the regular beam-line and the beam dump.
PurposeThe purpose of this paper is to design and test a bipolar kicker power supply principle prototype.
MethodsFor this purpose, a solid-state Marx generator circuit based on pulse forming network with insulated gate bipolar transistors is applied to the bipolar kicker power supply principle prototype.
ResultsThe experimental results show that the principle prototype has the ability to produce a bipolar extraction current, and the polarity can be arbitrarily selected. Besides, a flat-top duration of the extraction current adjusting from 0 to 1.23 μs has been accomplished.
ConclusionsThe output performance of the principle prototype satisfies the design requirements and verifies the feasibility of the design.
