Today Maico measured the thickness of three indium-plated inconel c-seals, presumably Ultra-Seal P/N 50606. These seals had NOT been in the Hot

Yesterday, Grant entered the Ante Room with David Wang to visually inspect the two sets of failed c-seals from the Heat Shield circuit, to remove the
second set from the Heat Shield water blocks, and to leak check the heat shield circuit with o-rings and a water-block-to-leak-detector fitting.
Some photos of the inspected seals are in the attached design review presentation. Some unusual marks were observed on both sets of failed |

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 |

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, |

Don Jackson brought to my attention some potential HV minimum spark gap issues with the source tray cooling lines. It appears:
- The gap between the Ground Electrode cooling lines (ground) and Heat Shield cooling lines (HV) does not meet the spec of 0.668" MIN |
