| 0937 | Stop flashing detector. |
|---|---|
| 0940 | Filled N2 cold trap. |
| 1024 | Test PID temperature control. P only, P=20 seemed too large. |
| 1035 | P=10 looked fine. |
| 1043 | P=15 introduced more oscillation than P=10. |
| 1100 | P=8 was not as good as P=10. |
| 1137 | P=10 and I=50 triggers oscillation. P might be too large. |
| 1147 | P=1 is too low. |
| 1150 | P=4 is too low. |
| 1428 | P=10 and I=120 seem to work fine. |
