After the scan finished I found the Test Stand EPICS screens whited-out. Decided with Friedhelm to leave it as it was for the night and to contact Controls next day to reboot it without tripping the heaters and the HV.

April 3, 2014:

Found everything recovered. Except: “SOURCES ARCH IS RUNNING” was red. So, I restarted it. Jane Richards and Friedhelm didn’t do any IOC reboot. Also found that the data from yesterday’s scan was saved (see the previous scan).

The target was cooled down and it's ready for the on-line installation.  Friday, June 13, 2014, 08:43: Turbos stopped. Vacuum at 1.2E-7 T Monday, June 16, 2014, 08:26: Venting. Water purged.

The target assembly did not pass the megger test between anode and heat shield after the previous conditioning. The AlN insulators were found to have failed during the conditioning. The coil insulation was burnt. AlN insulators and anode ware replaced.
