Changes made in the electronic during the break between 14N and 14O

1) T_VAMOS-CATS1
it was not connected. We added 500 ns delay in CATS1 (CATS2 in reality) (48+150ns before)


2) T_CATS1_HF
range changed from 2µs to 200 ns

update Adrien:
La dream team de Division (non) Opération n'arrive pas a mesurer l’énergie en sortie de CIME (WTF??!!)
Du coup ils ont mis une énergie fausse mais avec une super précision de 1.8 Mev/A dans la fiche.

T_VAMOS-CATS1 is now connected in T_CATS1_CATS2 as posted this night. We have tried to add 500ns more delay (800ns in total) to CATS and it did not work, so we suspected the TAC or ADC. This is why we inverted T_VAMOS-CATS1 with T_CATS1_CATS2. For this TAC, CATS is the START (and is not delayed by 500ns).

The charges are lower in RUN77 because bias was reduced to 580V.

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)
