The telescope has been mounted in there stand in G3.
- Detector are now mounted and fitted with their DSSD.
- BT test ok
- HT test ongoing

Fixed, e748, Wed May 24 09:35:00 2017, Adrien Matta, CATS, Hardware, , BTD chambers mounting in D6
|
Sebastient started mounting the BTD chamber in D6.
The frame is in place, BTD chambers one and 2 are mounted.
CATS1 is in BTD1, CATS 2 remain to be mounted.
The DIN flange for BTD2 is missing.
The chamber need to be Vaccuum tested before surveyor alignement. |

Fixed, e748, Thu Jun 1 09:32:38 2017, Adrien Matta, MUST2, Hardware, , MUST2 cabling scheme
|
The MUST2 cabling scheme has been change so Telescope 1 to 4 and 5 to 8 are on two independent set of distribution box and HV Card.
Telescope 1 to 4 are on the small distribution box and the first HV card. This correspond to the down stream flange.
Telescope 5 to 8 are on the large distribution box and the second HV card. This correspond to the port side flange.
CAEN SY1527 setting has been changed accordingly. |

Fixed, e748, Fri Jun 2 12:03:32 2017, Adrien, Laurent, Shumpei, MUST2, Hardware, , M2C vacuum test
|
We mounted 2 dry pump on the chamber and started pumping at 11h.
Pressure was about 6e-1 mbar around 11h45.
Waiting to switch on the turbo at 1e-1 mbar.
Gailor switch on the turbo during lunch time. We reach 2e-5 mbar, but the vacuum is oscillating. Gailor suspect the gauge.
We added a second gauge, it gave 2E-4, switch to a third one, same reading.
So first gauge to be changed.
we are gradually improving vacuum so we thinks it is plastic releasing gas.
Cooling switch on to -10, blocks are cooling down successfully.
All DSSD, CsI and SiLi works with rather low current (below 0.5uA).
After three day, vacuum level rise to 6 mbar. According to Vincent; this is standard for static vacuum, so no sign of major leak. |

Ongoing, e748, Tue Jun 6 17:57:07 2017, Valérian et François, EXL, Hardware, , Hardware coupling of EXL with MUST2

EXL seems to fit in Adrien's setup. We still have to check if it fits in the chamber. |

|
EXL seems to fit with Adrien's setup.
We still have to test if it fits inside the chamber. |

Fixed, e748, Wed Jun 7 11:29:55 2017, Adrien, MECH, Hardware, N/A, Surveyor mesurement
|
The surveyor are carrying out the measurement of the detectors in D6.
The measurement should take the day, starting with the main plate, and then in the afternoon the detectors.
All measurement done, WAITING FOR REPORT. |

Fixed, e748, Fri Jun 9 12:30:49 2017, Adrien, VACUUM, Hardware, , Vacuum Leaks
|
We reach a stable 1e-5 mbar. We performed a leak check and identify that the Ionisation chamber gate valve is not totally tight, I don't think there is much to be done.
One of the M2C flange also have a micro leak, that we will solve next tuesday when reopening the chamber.
NOW FIXED |
|
Fixed, e748, Fri Jun 9 12:33:25 2017, Adrien, MECH, General, , MUST2 position
|
After a the surveyor came we figured out the MUST2 telescope are 1cm too high with respect to the beam line.
Vincent is preparing new feet to replace the one supporting the main plate. We will support the plate with adjustable one while replacing the other so there is no need to dismount any detector.
NOW FIXED:
Vincent Morel and Laurent Meneger put in the new fit without unmounting the detector. all went smoothly. |

Fixed, e748, Fri Jun 9 12:34:18 2017, Adrien, DAQ, Hardware, , Hub
|
| We are currentlky waiting for the hub to be configured so we can start the MUST2 DAQ. Should be done in the afternoon. |
|
Fixed, e748, Fri Jun 9 12:35:46 2017, Adrien, MUST2, Hardware, , CsI trip on T6
|
The detector were left on during the night. T6 CsI trip and cannot be switch on again. Once we established that all the MUFFEE works correctly we will start investigating the issue, perhaps coming from the distribution box.
NOW FIXED:
Not really clear what was the issue, Most likely a loose HT cables on the feedthrough flange. |
