Fixed, TEST, Tue Mar 10 11:05:40 2020, Franco, GRIT, Hardware, 3-alpha, Trip in the cooling system after e775s experiment 
|
In the weekend after the experiment e775s (7-8 March 2020) a problem with the cooling system of Mugast occurred. In particular, in the morning of Saturday
7th around 12h the cooling system tripped and some detectors remained switched on until Monday 9th in the morning. After a check, it looks like all Mugast
detectors are ok except MG6, which cannot be biased anymore.

|
- MG6 (FZ) is disconnected.
- MG7 (500um) is dismounted and MG8 (375um) is replacing it.
- The Y kapton of the annular has been changed.

Fixed, TEST, Wed Mar 11 18:12:40 2020, Marlène & Franco, GRIT, Hardware, N/A, Update on Mugast
|
(Probably) final update of the status of the detector before the experiment:
- MG5 does not trigger on Y (no pulser, no alpha source). This can explain why in the last experiment we could not run the time calibration of its Y.

Fixed, TEST, Thu Mar 12 10:14:02 2020, Marlène & Franco, GRIT, Hardware, N/A, Debugging the cooling system
|
We realized that the increase of temperature of MG7 and MG9 during run 600 (alpha calibration) was due to the fact that a loop of the cooling system was
not working since the pipes were not properly connected. We re-connected them and switched on the low voltage without making the vacuum just to monitor
the evolution of the temperature.

Fixed, TEST, Thu Mar 12 14:47:59 2020, Marlène & Franco, GRIT, Hardware, N/A, Moving MG9 square to MUVI2
|
- Since we are not using MG6 anymore (card burnt), we replaced it with MG9 on slot 3 of MUVI2. MUVI4 is now unused. We changed the actions parameters accordingly.
- We cannot run the time calibration for MG9 because the pulser does not go through neither on X nor on Y. |

|
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.

|
We opened the chamber to verify the connections of the kaptons but they were all well connected. We checked with the tester the conductivity of the kapton
YA5 and it was fine so we excluded any problem related to the kapton. The boards are working properly (the pulser is well seen). We have to conclude that
the problem comes from the detector. We made another alpha source run and indeed the result is the same as yesterday -> 5 sectors working on Y. We also |

|
I managed to obtain the spectrum with the pulser on the annular (Y side, namely sectors).
The raw strip numbers where I should have the 16 sectors are: 14, 16, 18, 20, 22, 24, 26, 28, 36, 38, 40, 42, 44, 46, 48 and 50.
The 5 strips I could see with the alpha source are: 20, 40, 44, 48, 50.

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. |

The signals of the new S1 will be splitted among 6 Mugast boards, according to the scheme attached.
The HV for the S1 have been updated accordingly, with labels like MG11/CsIMGXX. |

|
We mounted the new S1 detector from Surrey with a new custom cable on several MUFEE cards using the CsI ASICs.
We managed to put voltage on it and get decent leakage current.
We modified the DAS parameters from CsI values to Si values (gain, shaping time, etc).
