Abstract

The new conceptual design of the full turn fast extraction kicker power supply system of the Spallation Neutron Source main ring will be presented in this paper. In this design, the extraction kicker power modulators will be located outside of the tunnel, as requested by the SNS Project. Its purpose is to minimize the components inside of the synchrotron tunnel. The high voltage modulator will use Blumlein pulser and hollow-anode thyratron structure, a parallel termination resistor and two transmission cables. Main advantages include: flexible system configuration for unipolar single drive or push-pull double drive of the kicker magnets, lower charging voltage, lower beam impedance, a lower number of high voltage cables, and a large design margin for implementation and future upgrade
