Entry  Wednesday, May 14, 2014, 19:01, Grant Minor, ITE, Maintenance, TM3, , HV short inspection at ITE 
Friedhelm Ames commented to me that there appears to be a short between High Voltage and Ground at TM3 at ITE.
Friedhelm, Anders and I initiated a survey by Andrew from RPG, and entered the Target Hall at approximately 5pm to visually assess the HV cover
at the MAA.  There was no clear indication of a problem.  We opted to wait for David to return as we weren't sure exactly what we were looking
Entry  Thursday, May 15, 2014, 14:38, David Wang, ITE, Repair, TM3, TM3, Bias short on ITE 
Anders and I opened the HV cover in ITE and did  a visual check inside ITE HV  cover and top of TM3.Bill was with us and took the pictures.
There was nothing obviously wrong when we opened the HV cover in ITE. We disconnected TM3 high current cables from ITE. Then we did an electrical check
on TM3.The TM3 was good and passed megga test (465Mohm at 500V). The module was good and was separated electrically from the ITE at that moment. Then,

When the Containment Box was opened today by Chad for a target change, we found the conductor insulator block B (ITD0054) to be broken close to the right
TGHT terminal. Chad was nevertheless able to remove the target. See DocuShare and

There were some problems this morning with provision of FEBIAD gas to the the target at ITE.  It was suspected that the gas line was improperly
connected to the module, or that the valves at the module were not opened.
Remote Handling was asked to open the HV cover on TM3 at ITE and check the connection of the FEBIAD gas line.  Grant Minor, Maico Dalla Valle,

Just some notes on the install of SiC#30 on TM3 last month...It was installed with all new fasteners and torque values provided by Anders were used...of
main interest is probably the main high current fasteners which were torqued to 150 in lbs.

SiC#30 has been removed from TM3. A quick exam of TM3 source tray did not  yield any obvious signs of damage.
9 pin connector on the target showed the usual sparking/arcing marks.
Heat shield has been removed from the target. Inside of heat shield has some unusual marks on it and quite a lot of black deposits.
