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. |

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. |

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. |
