Wednesday 30th May.
Run 2117 started at 8h36 ; Stop at 8h45: BEAM STOP.
Beam decreased at the end of Run 2116, still very low at the beginning of run 2117, 300 pps then 3 pps.
PCP told us that it should take a few minutes to recover it, but it will take more time (maybe 1/2 hour) to recover the beam,
due to vacuum problems before the target. The operators have to enter in the vault to check the equipments.
