Previous Day

  • Lab in-person: Matt
  • Virtual partner: Derek
1336 Matt Fritts body temperature = 98 F.
1415 Matt arrives at lab.
1435 Opened e-box and disconnected strip lines.
1450 Disconnect T-pipe and connect it directly to leak detector.
1515 Leak detector is below threshold for the just the T-pipe. Can't see any signals.
but… later when I turned the LD on the IVC, it also bottomed out. I recalibrated it and then it went back to the few pbarL/s level as normal. So maybe the first calibration was bad, and the t-pipe check is not valid.
1526 Adding layer of grease to surface of elbow clamp
1546 Reattach T-Pipe
1553 Reconnecting Strip lines to e-box.
1600 Finish sealing up the e-box, begin pumping on IVC with scroll pump.
1612 Switch to the Turbo pump.
1625 Turbo down to a few ubar. Switch to Leak Detector, background down to 70 pbarL/s, no signal rise when squirting around elbow and elbow flange, as usual at this point.
1650 Tubro down to 740 nbar, about to do another leak check.
1655 Matt leaves the lab.
1845 Matt Fritts body temperature = 98 F
