Fixed, e744s, Mon Apr 15 15:18:55 2019, 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)

|
Xf efficiency (normalized to CATS intensity) is directly linked with the beam intensity. The image below show a comparison between normalised Xf spectra on 3 different runs taken with different beam intensities:
Run 122 2019-04-13 06:31:00 4e+4
Run 130 2019-04-15 15:23:00 2.5e+5
Run 131 2019-04-15 20:41:00 2.5e+4
No dependence on time, dependence on intensity. |
