Fixed, e793s, Tue Mar 10 18:46:13 2020, Franco & Marlène, GRIT, Hardware, , Changes in MUGAST MG_X_raw_11032020.pngMG_Y_raw_11032020.png
- MG6 (FZ) is disconnected.
- MG7 (500um) is dismounted and MG8 (375um) is replacing it.
- The Y kapton of the annular has been changed.

Attached the alpha source spectra acquired on March 11th after the changes described above.
- MG8 looks better than MG7 but it looks like a part on X that was missing on MG7 is also missing on MG8, it can be due to a kapton.
- The annular behaves exactly as before and during e775s, the change of kapton did not solve the problem.
- MG9 here was not biased (it is on the MUST2 box).

At around 19h we started the alpha calibration run for Mugast+MUST2+square with pedestal suppression and cooling at 0 degrees.
We also took screenshots for HV and LV before and after the run.

After 2h30' of run we checked the temperatures of the boards and we noticed that MG7 had 63 degrees on both X and Y, which is very high; MG9 was around 56 on X and 26 on Y. There might be a problem in the loop of the cooling system because the other detectors are pretty fine, with temperatures around 20-25 degrees.
In attachment the evolution of the (calibrated) DSSD energy for MG7 during the run.

We start the alpha source calibration run with pedestal suppression (except for MG7 and MG9) and cooling at 0 deg.
The HV for MUST2 are in attachment. It is not clear whether they will remain unchanged during the experiment since some currents are high.

What remains to be done
- Do the time calibration of all boards (time calibrator has to be connected)
        . When checking the pulser on all boards we saw that MG5 has no triggers on Y and MG9 does not see the pulser (neither X or Y). So we will not get time calibration for those
- Plug the STOP in the MUVI (either clean HF that was used in the previous experiment or CATS2 clean that was also prepared during the last experiment but should be connected)
- Rename parameters in the GECO of the experiment
        . We now run only with 3 MUVI, MG9 (square) is put in channel 3 of MUVI2 (where MG6 was plugged before)
        . We changed the names for the ACTION_mugast.CHC_PAR but it has to be done for the experiment file)
- Targets will be mounted last week before the experiment. The surveyor have to remeasure the position of all targets.
- hvm_watcher has to be modified according to the changes made on the distribution boxes : 
        . MG9 is on the LV/BT of the new distribution box on channel 6
        . MM1 is on channel 5 of the MUST2 distribution box (instead of channel 1).


We noticed instabilities in the current of the MUST2 detectors : T1 is fluctuating from time to time and T2 current is increasing slowly but surely.
We now run with 60V on MM1 and MM2 and 70V on MM3 and MM4.
The fluctuations on MM1 are usually solved when cooling down to 0 degree.

!! We do not leave HV and LV on when there is nobody to check the temperature of the boards and the coolers.

MUGAST is undervacuum thanks to Arnaud and Laurent.

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

we ran FSC on all card. S1 is dismounted.
Pulser goes on all channel and works well so electronic is fine.
We will ask Laurent to remount the detector and re run the test.

Arnaud open today and change the Y Kapton (YA5) of the S1. Everything under vacuum/cooled again so I ran FSC, hopefully this will fix the issue we have with the Junction side.
