Determined on Friday April 16th that the water leak was on the coil negative circuit. This was determined by circulating water through once circuit at
the time. Only HF and GE tested (not Extraction Electrode). |

Vacuum is at 3.6e-6 Torr and possibly still dropping. Starting HV tests with just a tube and wire hanging down from the feedthrough. Turned on
power supply and started raising voltage. |

Feedthrough R had a flange installed with a HV feedthrough on it for TM3 service tray prototype HV tests. It was replaced today with the original blank
flange. |

When the new RGA arrives it will be changed. |
