This cavity and others in the zone has had numerous arc faults and running 3Mv/m. Some special arc detectors with blue test ID's have been installed and aren't testing correctly since being installed and might have to be changed out next available access to downstairs. Cavity 8 had one of these blue LED arc detectors and running at 7.1 Mv/m but it's the highest gradient in all 8 cavities and even it has been de-rated. Need to look at this zone in detail to see if this cavity has always been this bad or if we have a arc/ir chassis problem that needs replaced !! Jay B.

The spare FDU received a new filament power supply and was bench tested at which point it was swapped with the faulted FDU. The system was restored and MCC was able to begin separating beam. An eLOG entry detailing how to restore the separator when it has a locked it bias voltage fault was also made.

Enter W1 through the west end door. Turn left and find rack W104B02(see Pic). Go to the rear of the rack to access the FDU 120 VAC switch. (See Pics). Turn off FDU 1's switch for 5-10 seconds.
Turn the switch back on and then attempt to reset the HVPS and RF separation. You do not need to be QEW qualified to perform this procedure!
