- Checking the LN2 portable (180L) dewars. Note: If snow falls, we must put the LN2 portable dewar inside the NM4 hall near the loading dock because, due to cold, the 22 psi relief valve on the dewar will freeze and keep venting all the time, which will empty the dewar soon. During beam operations, we cannot put the LN2 portable dewar in the NM4 hall.
- The material (CH2/CD2 & NH3 (10g)) is filled with LN2 in the target preparation/handling area. This activity should be performed weekly. Check with the target expert for the week and arrange the material dewar refill with LN2.
- Checking the ODH sensors reading for the NM4 hall (for cryo platform) and NM4 ground level (for NM3). Please put the reading for four sensors, two for the cryo platform (ODH 1 & ODH 2) and two for NM3 (ODH 1 & ODH 2), in the above spreadsheet.
The normal reading is 20.8. If it is changing \pm plus or minus 0.3, then first inform to Prof. Dustin and Kun. If they let you to send an email to Kun, Evan and Kim (overhage@fnal.gov) then do that.
- Recording the pressure gauge value for the LCW supply to the Roots pump. Please see the following pictures, whose value needs to be recorded in the above spreadsheet.
- Note: If the pressure values go below 50 psi or goes above 55 psi, please inform in the discord channel.
