|
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.

|
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.

|
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.

|
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.

We had problem with MUVI1 (pre serie 1) not working properly when a telescope was pluggeg (but fine otherwise).
Charles Houarner changed the card to MUVI serie 5, and the card is now working. |

12Th June. 3-peak Alpha source rotated towards the telescopes MM1 to MM4 (square wall of 4 telescopes).
MUVI configurations are fixed on the DAS. See pictures below. Thresholds : 402 keV.
We have DAS error messages for telescopes T2 and T7 with problems of data transmission, "I2C errors" = logic signals problems, maybe due to

It appears several SL cables are faulty.
To avoid manipulation of all the cable we now have T1-4 working. These required to scavenge SL T5 and give it to T2.
