Diego | VAMOS | General | | Saturation in the WIRES of Drift chamber due to Pile-Up |
| There is Saturation in the Energy of the WIRES due to the Pile-up, it is not urgent to correct it because these parameters are not needed for the reconstruction. Tomorrow morning, when stopping the run, we should change the offsets in NUMEXO in order to better allocate the amplitude of the signals. |

Beyhan, François | OTHER | General | | Alarm in G2 but no beam stop |
Same issue as Saturday evening.
Alarm in G2 at 12:30 due to Exogam filling with liquid nitrogen.
Beam was not stopped.Acquisition of data ongoing |

A. Lemasson | VAMOS | Hardware | | Change of Offset in DC Numexo |
- Increasing offset to minimize saturation.
- Reducing DC Threholds
- DC0 436 ->355 mV
- DC1 255 ->255 mV
- DC2 269 ->269 mV
- DC3 600 ->433 mV

A. Lemasson | VAMOS | Hardware | | Test Run 127 : Change if IC Shaping |
Try to change IC Shaping to solve the pb of Continuous Line in IC0 vs IC1
Change Shaping on all IC during run 126 Change Chan 5-12 from Filter B (3us) to Filter A (1us)
Regarding The line IC0 vs IC1 :
- If Filter A The y =x line disapear, but the resolution deteriorate (22% compared 9 % in Filter B)
- No clear effect of the Thresholds of
- No clear effect of decay time on the resolution

A. Lemasson | VAMOS | Hardware | | Optimization of IC Shaping |
During Run 129,
1) investigation of the trapezoidal filter of IC
2) The Conclusion is that if we reduce the shaping to 2.5 us we reduce the random line in IC vs IC (At 1e5 in VAMOS : Random Line / Peak is 18.5 % compared to 40% for shaping of 3us)
3) The 2.5us us also optimum for the resolution (oscillation of the abse line after the filter very sensitive to K, with freq of ~500Khz)
