Discriminator setup for GEM and PMT's
The time period for counting 1 min.
- GEM (amplified 15)
| Voltage (V) | Number of Counts (5min) |
| 0.3 | 9 , 16, 26, 32, 46 |
| 0.25 | 62, 138, 208, 267, 329 |
| 0.20 | 259, 618 (2.5min), 767, 1001, 1241 |
| 0.19 | 1030, 2100, 3200, 4300, 5391 |
| 0.18 |
- PMT (R)
| 0.3 | |
| 0.25 | |
| 0.20 | |
| 0.15 | |
| 0.10 | |
| 0.05 |
- PMT (L)
| 0.3 | |
| 0.25 | |
| 0.20 | |

Counting without a source (Background)
GEM and Sci. in coincidence (and gate), GEM oprating voltage is 2.7, 3.1V GEM and cathode successively, both of the PMT's has 1kV input voltage.
