The beam was stopped at 4h56, due to the alarm of "water leakage" on equipments, indicated in the D6 area.
All QPole in D6 were automatically put to 0.
Wien filter and DAP were put OFF to stop the beam and enter in the D6 area.
Between 5h and 5h30 PCP investigated the problem along the D3 and D6 areas, to check the water leakage problem indicated by the control command messages.
Since the problem could not be solved directly on the command boxes in PCP, it was not possible to put again the values on the QPoles.
then the area astreinte, Sébastien Le Moal, was called at 5h40.
At 6h15, he investigated the problem and check the cables in the D6 area. He saw some water condensation around the cable surveyor of the equipment (located behind the cooling system of MUST2).
Night/morning shift team: Louis Valérie.
[NB: in order to let them end up their night quietly, we will call later on the LISE experts for the beam line checking once the Qpoles are ready to put ON again.]
The T4 was increasing, from 16µA at 5h, then around 17 µA at 5h40 (see snapshot HT_MUST2_Wed30May_At5h52.png) we decided to put it OFF to let it end the night quietly.
