We are developing techniques for processing the high gradient (75MV/m), X-band accelerating structures for the NLC. Accelerometers attached to the structures detect surprisingly large acoustic signals, believed to be due to the RF heating. On a pulse which causes breakdown, these signals increase substantially, producing up to 50 G acceleration at 20KHz. The timing and amplitude of these acoustic signals can provide information on the location mechanism of the breakdowns.
