Timing issue between vamos and mugast

A cut is seen on the TAC between MUGAST and the focal plane multiwire of VAMOS when one select XF or DC0_Y>-1500

Edit: This must be a reconstruction problem as it is not seen in the Raw files (using DC0_X for example)

Edit: This is not only a reconstruction problem as the cut appear again if one select DC0_Y

Edit: We changed VAMOS FAG validation window from 500ns to 800ns

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

2) T_CATS1_HF
range changed from 2µs to 200 ns

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).

14O8+ beam characteristics

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.

Using the value of the HF=83,4ns. We can obtain the calibrated plot of T_CATS2_HF which is joined and gives us roughly a 2-3 ns resolution for the HF

run77 CATS efficiency

CATS efficiency has been computed for run 77 using T_FagHF an T_Si_Cats1 with different triggers:

Trigger GATCONF_MASTER<8 (MUST+Mugast) : 94%
Trigger GATCONF_MASTER=4 (MUST) : 99.4%
Trigger GATCONF_MASTER=2 (square) : 85%
Trigger GATCONF_MASTER=1 (trapezoidal+annular) : 22%

The 22% resolution is due to the fact that the trapezoidal detectors are noisy. Doing the same on an analysed run we obtain ~ 85% efficiency

In case of a CATS2 tripped

Currently, CATS2 is inserted, if the window :

CATS2 has tripped appear, one should do the following :

Open a terminal
Type: HV
Username is : admin
Password is : admin
Press enter twice

The list of channels is going to appear.

Using the arrow of the keyboard, go down until you reach cats2
then go right until you reach Off
press space, the dectector should start ramping up
If it trips again, you can try to put voltage to cats1 (right above cats2)

Two possibility :

If cats1 trip it is the gas bottle that is empty call : 07 83 34 30 81 (Sebastien)
If cats1 doesn't trip try cats2 again, and if it trips lower the voltage of cats2

To lower the voltage of cats2 : go to the left until you reach the first cell after cats2 name and lower the voltage 10 volts and try to start cats2 again.

THEN CLOSE THE TERMINAL
