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.

Due to some water leaks, CSS1 CSS2 and CIME as the vacuum system of GANIL are down... Time loss could be considerable... They talked about beam possibility
in the morning but it seems unlikely. |

After waiting for 1-2 hours. I started the BT again on T5 no tripping BT anymore. While writing hardware with DAS T5 responded well.

After a quick analysis, we can conclude that MUST2 is working for resonant elastic scattering. We find a resolution of 125 keV which will improve with a
better analysis, as we are using a basic calibration for CsI Energy. |

|
The target seems identical between the two runs... We will have to investigate to understand what is going on.
The decision is to change the target 5 for the target 4 104um from georges.

After correcting position for the Must2 detectors by taking into account the real hit position on the target that was (0,15cm,0) and not (0,0,0). The way
to do it was to artificially move every detector 15cm lower.
