They succeeded to get 90 % transmission with CSS1 but the energy at the exit was changed by 4%, that is not compatible with the CSS2 limit of 1 %. After
fitting the CSS1 energy they obtained 70-80 % transmission only, but it is enough. The problem with the HF of CSS2 was solved. They are trying to accelerate |

Monday 28th 16h10: we refill the cooling system for MUST2. The level should be ok for the rest of the experiment.
(Around 4 days). |

CATS2 current fluctuates a lot and has increased up to 0.26uA in run 340
In run 340 I observe that a second wire is missing, which is new (see attached file for run 339 and run 440) |

Weird signal on StripX of T6... might be the copper oxyde projections making a short-circuit
[U][B]EDIT 27/03/18 : The problem seen on Telescope 6 might be due to either some Asics Problem, or due to some dirt, the current reason in not known currently. |

We can see that the DSSSDs on T1(CsI) T3(CsI) T4(CsI) and T5(SiLi) are in good shape (cf :[URL=https://elog.lpc-caen.in2p3.fr/MUST2/333]Bidim for T1 T3

|
After checking the cable of T6 & T7 it seems that there were in fact an inversion during experiment e748. T6 is the bottom one, and T7 the top one.
During e748, it seems that there were some difference regarding the position, between the hardware and software position...

The EXL detector has been mounted, it is very close to the target ~4cm and doesn't do any shadow on the M2 telescopes. But it isn't at 90° anymore. The
cable have been plugged-in (cf photos). With a new mapping of the detector (cf drawing). |

Today we found different problems, no time on T4 and no signal on T5 and T6 CsI tripping. After changing cables and a lot of tests with the chamber open
and only the BT ON, T4 and T5 problems seemed to be fixed.

Yesterday night we tested T1, T2, T3, T4, T5, and T6.
All telescopes (except T6 which still have a "tripping" CsI) have an Energy and Time signal on X and Y!
