| 5609 | 4060 | 30 | 6850 | 6850 | Cf252 in. Coincidence between HPGe and timing PMT | A ToF spectrum exists but is very hectic. Problem may be that the TDC stop is determined by a widened timing PMT pulse in coinc with a HPGe pulse that has high timing jitter. |
| none | 1250 | 26 | 2800 | 9655 | Not taking data during this time. | |
| 5611 | 2509 | 30 | 4230 | 13885 | Cf252 in. Coincidence between HPGe and timing PMT. TDC stop always 1200 ns after PMT timing pulse, otherwise same setup as 5609. | ToF looks good. Neutron rate approx. 3 Hz for detector 90. |
| 5613 | 10025 | 15 | 0 | 13885 | Na-22 source. Coincidence between HPGe and timing PMT | |
| 5614 | 654 | 15 | 0 | 13885 | Co-60 source. Coincidence between HPGe and timing PMT | |
