  • Lab Update - Run 80 preparation
    • We are still at 77K!
    • Diagnosing the issues below:
    • He4 pump issue: * Discussed with Matt and found that the “smoke” should be “whitish oil vapors” which Matt have seen sometimes.
      • Refilled Oil in the pump by following the instructions on the pump manual
      • Donot see vapors after that
    • Leak at the stripline/Main Bath region: Tightened all screws on the Main Bath, a few of them were turning half a degree or so. Signal didnt change much
    • After multiple trials, the leak seems to be more on the stripline elbow joint, but vacuum is under 7e-6 mbar.
    • Ping and Guilia were not available yesterday to get the initial transfer done in the afternoon time, so we will try today.
