Voltage Breakdown in a 420 MHz RFQ Structure


Designs for Radio Frequency Quadrupole (RFQ) accelerators of reasonable length require operation with surface fields above the threshold of Kilpatrick's Sparking Criterion. A cavity was designed using SUPERFISH to test the validity of this criterion and to determine operating limits for the Los Alamos Proof-of-Principle (POP) RFQ. The testing was done near… (More)
