XBOX-1 Progress

31st July 2013

Progress

• New 16-bit attenuator and PID control for amplitude.• E-logbook is back with regular (almost daily updates).• ECL counters communication problem (24hr delay)• Started running with uncompressed pulse 19-07-2013.• DAC which creates the phase program for pulse compressor

had been “updated” by control group. We ran without a compressed pulse up to ~10MW.

• Shortly after the pulse compressor was brought back online it detuned due to a pause in running. System was restarted with RF -> 10MW 1.5us pulse into the structure-> new software written to monitor pulse width and shut-down if needed.

• 19.8 MW 68MV/m reached at 50ns so far…

128 hrs of CERN T26 Conditioning (50ns pulse)

Heavy Clustering occurred due to PC detuning-> 1.5us pulse into structure.No damage done (hopefully) only ~100 BDs and low power <10MW.Problem has been fixed with addition of pulse width monitor.
