- Lab Update - Run 81 preparation
- LN2 transfer on Friday. Mini-leak test suggested by Prof. Paul showed no leaks.
- Final leak test done yesterday since bg levels were at 10^-6 mbar L/s (high).
- Turbo pumping over the weekend helped to lower down the level.
- During transfer stick removal, there was a leak signal but it seems to be not related to the indium seals.
- LHe transfer completed yesterday.
- Plan is to do another LHe transfer today and start circulation.
- Priority Updates
- People using jupyter notebook server on CDMS2: Don't forget to terminate the server after use. It does not shut down on its own and eats up the resources (Bad for other users).
- Opportunity for detector operation training: see Ray's email.
- General Updates

- Event duplication issue:
- Elliot had noticed that R79 RQ data (and raw data) has duplicate events.
- Investigation into this issue shows same ~127-128 events repeat for multiple times. The issue is in the raw data itself.
- R76 looks fine.
- We suspect same physics events have different trigger information therefore being treated as different CDMS events.
- Different trigger settings for R79? Checking ODB keys.
- Trying process the raw data with latest version of cdms software. It does not work.
