There is a continuous decrease of efficiency in the Drift Chamber. The efficiency of IC is also not optimal. I suspect that with this beam intensity (5x10^4 in VAMOS) detectors may start to suffer some damage. If the efficiency keeps decreasing we need to consider to reduce the beam intensity.
In order to check the efficiency, there is a script in /home/mugast/Analysis_e744 called EffCheck.C
Open a root file: root -l RootA/r0XXX_XXXa.root
Load the script: .L EffCheck.C
Launch the script: EffCheck() (the calculation is automatic) |
