SNS* Ring Extraction Kicker System

Abstract

The spallation neutron source (SNS) has recently completed the commissioning of its 1.0 GeV proton storage ring, which included the ring extraction kicker system. This extraction system is comprised of fourteen high-voltage Blumlein-configured pulse-forming networks switched by fourteen thyratrons. The system also includes fourteen Blumlein control racks, which provide a high-voltage source, monitoring of interlocks, and signal conditioning to the system control racks. The four-system control racks are for adjusting timing and monitoring of the charge voltages and current pulses at the kicker magnets. The kicker system is then controlled by EPICS, the accelerator's control system. The kickers were designed at Brookhaven National Laboratory as in companion papers (BNL), and built to print by Applied Power Systems, Inc., (APS), of Hicksville, NY. The hardware and software utilized and the commissioning results of the fourteen Blumlein kickers will be presented
