| Run Number | Date | User | PMT | High Voltage | Experiment | Description and observations | Image |
|---|---|---|---|---|---|---|---|
| 2759 | 11/12/2015 | Marco | XP2262 (SN 34426) | -2.300 (NIM) | Gain | LED (green) gain calibration for NPS light yield. Na22 source is also inside, so may have noise. Rate of ~6.5kHz. T=18oC. SEP: 66.67 (fit range 50-85). PED: 27.66 (fit range 25-35). | Error creating thumbnail: Unable to save thumbnail to destination
