| 0855 | Fill IVC with 54 mbar N2 gas. |
| 1530 | Tower removal procedure commenced. |
| 1730 | Tower removal complete. G102 taken to clean room. |
G102 detector level resistance check before removing it from the tower. DIB pinout.

| 1135 | Checked G102 resistances again after removed from the tower. No substantial difference found before and after removing the detector from the tower. The high impedance heater on Q4 may possibly be from the crystal bulk or surface breakdown. |

| 1635 | Checked sidecoaxes used in the run to make sure the heating effect was not from them. A uW scale heating power would be generated by uA current through a MOhm resistor. Even if there were something wrong with the sidecoaxes, the DMM would not be able to detect it. Anyway, they are checked out OK. |
