Monitoring of beam profile with BAF2

In order to provide a efficient way for PCP to monitor beam profile a new TAC measurement has set up.

A BAF2 detector has been inserted close to the reaction chamber (in position 7 of AGATA structure frame). Operating voltage of BaF2 is 1800V and the typical signal amplitude is above 100 mV.
The output signal is sent to a TFA (with gain =1). No additional delay was used. The BAF2 trigger signal is made from CFD and used as a start a TAC. TAC range was chosen to 1us.

The trigger signal was also sent to GMT trough input nb 5.

Modifications of set-up

We have installed the new MUFEE board in the reaction chamber for MG2. This board is a new version with ATHED.

We have moved the MG9 board to become the board to read the future MUST2 detector at 90 deg. This board is now perpendicular to the other ones. We have tested the kaptons connection to the detector and the placement of the detector.
The design will be refined on monday with Patrice.

The board that was reading MG10 is now used for MG6.

Every board has been tested again with pulser under vacuum. Everything seems OK.

NOTE: one mask is not properly screwed (top left) and should be mounted again on Monday morning when we open.

Masks cover theta_lab < 38 deg, corresponding to < 30 pps of 15O for 15O+19F elastic channel assuming 2e7 pps of 15O and 1.25 mg/cm2 of LiF.

Yesterday at around 23h the CAEN alim stopped working.
- The 48V power supply is blown up
- The Main controller is still starting
- We can see all card from the powered crate so hopefully no damage on the card themselves

Nicolas left a 6am this morning to pickup a spare at Orsay.
In the mean time we run 15N with VAMOS-AGATA daq.

I switch on all BT and HT. everything fine so far. Keeping the HV to check there is no trip on the silicon

MUGAST undervacuum and powered up

Tue Feb 2 16:41:17 2021

I put back the supply of MM1 to the channel 1 of the MUST2 box (as in the normal configuration) and polarized the detectors to make a rapid re-check. I didn't see any detector tripping. MM1, switched on only for a couple of minutes, had a stable current at 1.3 uA. The stability of the detectors over time should anyway be checked better tomorrow leaving them polarized for a longer time.

MUGAST detectors status --> MG4T

The problem of MG4T ha sbeen solved by changing the feedthrough.
The pulser on Y was not working and we were seeing no events (no ORD) because there was a problem with the bias of board. The issue is due to the feedthrough.
So now MG4T (HT &BT) are plugged in a free feedthrough (below MG1T) and I see pulser signals on Y.

The bias seems to apply normally on all detectors (in the dark).
The pulser is seen on each boards.
I have put back aluminium foil on square but I could not test it.

The first plot attached has been done by artificially removing 7 deg in theta lab, just to see if the the kinematic lines of 47K(d,d) and 47K(p,p) can be reproduced. Of course the energy losses are not optimized in this case but anyway the agreement seems nice.
In the second plot I moved MM5 forward (in z) by 17.5 mm, without any re-orientation in x and y. We should compare this position with the one measured by the surveyors.
It looks like we have plenty of protons in the target but actually the Rutherford cross section at 80 deg for (p,p) is 4 times higher than the (d,d) one. From a quick estimation the ratio 2H:1H in the target should be around 3:1 (to be checked!).
