Valerian | OTHER | General | N/A | Particle identification with CATS or HF |
After discussing about using the HF, I join as a reference what was obtained during experiment e744 of last year. We can see that using an external TAC the time resolution is much worse using HF.
I also join as a reference the same timing using MUVI.
Edit: Added simulation with 3 different time resolution.
Joined plot are :
- TAC MUST2-CATS
- TAC MUST2-HF
- Calibrated ToF on MUVI
- Simulated : CATS (500ps resolution)
- Simulated : HF best case scenario (2ns)
- Simulated : HF as in previous experiment (4ns)

Valerian | CATS | Hardware | N/A | 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 |

Valerian | RUN | General | N/A | Procedure to follow during runs |
At the beginning of a run :
- Do screenshots of the scalers and add them to the elog.(Say it is at the beginning of the run)
During a run, one should :
- Check regularly the scalers.
- Look at the different pages on vigru.
- Check if there are any problem concerning the Voltages, a window should be prompted to you if it is the case. If the window has FP written it is on the VAMOS side.
- Do conversion, see corresponding entry (Or paper next to computer)
- Check the last pending issues in the elog and if they are fixed, edit them to fix (any HV trip or over-current are pending and shoudl be switch to fix).
Every hours and before stopping the run:
- Do screenshots of the scalers and add them to the elog.(Say at which time it is done)
- Do screenshots of all the vigru pages of MUGAST and VAMOS and add them to the elog.

While doing the electronic scheme, I saw that the Inspection line was inducing a bad signal in the coincidence module between fag and CATS1. See joined image.
Also, I broke a cable between CATS1 Fifo and the delay box, the delay is now 2 ns longer. |
