|
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 |

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:
