Module testing
The BAT modules were exposed to a Sr-90 beta source that was placed just above the active "window". All modules were configured ok (both singly and with all four modules at the same time. Below is a table of the pedestals and noise for the modules.
Module | Pedestal | Pedestal | Noise | Noise |
|---|---|---|---|---|
1 | 2000 | 2000 | 40 | 20 |
2 | 2000 | 2000 | 65 | 20 |
3 | 2000 | 2200-3000 | 25 | 20 |
6 | 1000 | 1200-2000 | 35 | 20 |
Module 2 has a factor of ~2 higher noise and did not display a nice picture of the source as the other modules.
