Four FEBs intsalled from external to middle:
- TDC 5, First serie, strip 1-12
- TDC 8, Second serie, strip 13-24,
- TDC 6, second serie, strip 25-36
- TDC 7, second serie, strip 37-48
Each of it is reading 12 strips both side. The mapping of the 12 strips is the following:
| Strip | TDC channel High Radius | TDC channel Low Radius |
|---|---|---|
| 1 | 10 | 14 |
| 2 | 6 | 11 |
| 3 | 2 | 7 |
| 4 | 0 | 3 |
| 5 | 4 | 1 |
| 6 | 8 | 5 |
| 7 | 12 | 9 |
| 8 | 16 | 13 |
| 9 | 18 | 15 |
| 10 | 20 | 17 |
| 11 | 22 | 19 |
| 12 | missing (23) | 21 |
The channel 23 is not connected to a lemo in the current version of firmware. Upgrade version of firmware with the correct connection will require a new calibration of Petirocs DAC
