During yesterday's (4/16) maintenance period, a Norco tech came to the site to inspect the 8 LN2 dewars that feed the cryopumps. Inspection report will be posted to Q2000008 once received.
The vacuum jacket pressures were also measured during inspection:
Dewar | Pressure (micron/mtorr) |
CP1 | 68 (gauge fluctuated may need replacing, lowest value recorded) |
CP2 | 26 |
CP3 | 68 |
CP4 (not in service) | 110 |
CP5 | 9 |
CP6 | 33 |
CP7 | 48 |
CP8 | 77 (gauge fluctuated may need replacing, lowest value recorded) |
