PIP Update Talk Booster Notched Beam Kicker Pulser General Talk The Long and Short of It S. Chaurize October 24, 2012
Current Plans Current BKED (Long) design kicker have a fill time of about 35-40ns Short BKEE/BKEF kicker modules are about half as long. They will produce a rise time of about 20ns. The voltage propagation time through the short kicker is cut from 20ns to 10ns due to half length. Two short kickers will rise faster with appropriate pulser to reach a desired flatop value. We will use a ANU style pulser using a CX2610 hydrogen thyratron rather than the existing CX1168 tube. One Pulser can drive 4 magnets
Current Plans Chris Jensen and EE support group is currently working on acquiring and building ANU style pulser. Pulser components will be built through out We hope to have one pulser operating in a test configuration by the end of We will try to convert one long kicker to a pair of 2 short kickers as soon as feasible(2013/14)

BKEE02(Short Module) Voltage ~40kV
BKED012(Long Module) Voltage ~40kV
Preliminary Finding is a 8-15 ns difference between ANU pulser and Operational Booster pulser(Slower) Testing by Jensen, Chaurize
Kicker Matching Issues Testing of kicker modules has been in progress. Resolving impedance issue with first version BKEE design to BKEF version still in progress. Currently we have 3 short kickers made. 2 modules are of the BKEE design that are usable but not optimal in regards to their impedance. Testing version 2 kicker series BKEF.
