|
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 |

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, |
