Vped scan March 26 2025
Summary from March 27th noon:
We have 4 tiles with problems:
EW1 PP06 TT01 - simply dead
EW1 PP06 TT02 - shows nearly always mean 0
EW1 PP02 TT09 - mean 0 (non zero in camac off)
EW0 PP07 TT24 - always mean 0
================================================
I did a scan according to blog but using pedestals like a year ago Mike's blog .
We took pedestal_rhicclock_clean runs with vped: -60, -40, -20, -10, 0, 10, 20, 40, and CAMAC off one.
We tried vped = 60 but we could not take the pedestal run.
Runs:
| Vped | Run number |
| -60 | 260805044 |
| -40 | 260805045 |
| -20 | 260805046 |
| -10 | 260805047 |
| 0 | 260805048 |
| 10 | 260805049 |
| 20 | 260805050 |
| 40 | 260805051 |
| CAMAC OFF | 260805056 |
I ran Mike's code over the outputs and also looked at the pedestals individually.
The outputs are attached: Scan Results and multiple pdf corresponding to each pedestal run.
there are multiple channels with "problems", below is the table with some comments to each of them:
| Eq Bd Ch | EW PP TT | Comment |
| EQ3 Bd 4 Ch 13 | EW1 PP06 TT01 | DEAD ! Since last year and in 7 pattern |
