|
The two run for MUVI 1 are larger than the run for MUVI2 and 3.
I think this is due to the noise on MG4 that create a lot of Data but it need to be investigated.
The run are now converted to root using offline.

Fixed, TEST, Wed Feb 3 16:42:41 2021, Franco, GRIT, General, 3-alpha, Status of the set-up (February 3rd 2021) 
|
We re-mounted the annular, put the source and cooled down to 0 deg. Voltages and spectra are attached.
MG11 has a very high current (15 uA) but stable. MG9 started from 2 uA and its current is slightly increasing. The MUST2 detectors don't show anymore that oscillation in current that we observed one year ago. MM3 has a higher current (2.9 uA) with respect to the others.
Only 5 sectors are working for the annular, 8 less than last year. We need to check whether it is a problem of the kapton or of the detector itself. |

Short alpha source run (not saved on disk) to test the detectors.
Summary :
- MG1,3,4,5 and 7 are all OK (few more strips missing on Y)
- MM1,2,4 OK
- MM3 has a lot of strip missing both in X and Y and current has increased wince last campaign (4uA)--> katpon should be checked |

| MG1 has some issue with the HT cable (for the BT bias). There is a shortcut only under vacuum. We checked the connector but we have to do vacuum again to check it. |

MG9C (thin square detector coupled with thick square detector unplugged) noisy
On X channels --> no noise problem ( about 100 ORD in the dark)
On Y channels --> MATE 10 & 11 noisy ! (see picture below with noisy Y piedestals)
With internal pulser (trigered by CK_TST) the counting rate is OK only if the thresholds are set at 1 MeV. If they are set at 500 keV, the counting rate is 10 times higher than the CK_TST
For MG10C, ORD is OK ! |

Pending, e793s, Mon Mar 15 00:21:18 2021, Sarah, Louis, Charlie, BEAM, General, CD2, Source is running out
|
The beam intensity spiked to 9x10^9, so Louis called PCP to ask them to reduce it. He was told that the source was almost depleted, and was presented with two options:
A) Keep pushing the source and run at 5x10^5, but run out completely soon (probably during the night shift)
B) Let the rates slowly drop and open the slits as much as possible, to make the source last longer (perhaps another day). This option is strongly preferred by the PCP team, and is the current plan we are following.
Changing the source would apparently take ~12 hrs. There will be a large meeting of all of the technical staff - including the beam and source experts - tomorrow morning at 09:00, so there may be more information about the best course of action after that.
Wilton was consulted as one of the spokespeople of the experiment, and he approves of this action. |

Fixed, , Thu Jul 11 11:40:18 2019, Marlène & Franco, OTHER, Hardware, , Some changes in the electronic scheme
|
- We checked the TACs with a time calibrator, all of them are working. Maybe to check the ADCs if some timings are not there during the exp.
- We set the possibility to have MUST2 divided by 100 (on a separate chain) in case of high rate on GMT channel number 7.
- We are now taking as input of the HF the clean HF validated by VAMOS instead of cleaning it on our side through the coincidence with FAG. This is sent to make the STOP of all TACs and MUVIs.
- We sent the OR of MUST2-MUGAST-SQUARES in an additional FIFO with cables of the same length (10 ns) and the output sent to VAMOS and to the TAC called Si-CATS in the acquisition. |

To launch this calib, redo a write hardware with DAS before.
Then do a ./calibT_SingleChannel in the xterm of RCC.
electronic scheme is as follow :
Time calibrator start -> MUVI
-> start TAC MUGAST HF
Time calibrator stop -> MUVI
ORD of MUVI -> Delay (550ns) -> stop TAC MUGAST HF |
