| Run Number | Amp level | discriminator level | Notes | |
| 5925 | 50, 4 | 3.6 | shutter close | |
| 5926 | 50, 4 | 3.6 | shutter open | |
| 5927 | 100 | 3.6 | shutter open | |
| 5928 | 200 | 3.6 | shutter open, high amp level | |
| 5929 | 100, 10 | 3.6 | shutter open high amp level | |
| 5930 | 100, 7 | 3.6 | shutter open | |
| 5936 | 100, 7 | 0.1 | shutter open, noise peak channel 74 | |
| 5937 | 100, 7 | 0.1 | shutter open, V_cath = V_GEM,noise peak channel 74 | |
| 5948 | 100, 7 | 1.15 | shutter open, detector is on, no signal overlapping, reached to te signal highest rate, with almost 100% signal to noise ratio. |
The following run has the same setting as the last run, unless there is achange written in the notes.
