00:00 waiting for beam
00:20 MCC call. they will try to send us low current beam.
00:45 MCC call. they still investigating the Hall C laser & will try to send 10 uA beam . but didn't succed
02:15 MCC call, They still have trouble with the Hall C laser . no estimate of how long it will take.
Then we decided to tabe DNL runs
03:30 MCC call. The hall C laser is now OK. We will have the beam soon
04:00 After we replace the Meantimer cable and restore the half gain HV-file
det 1 and 12 on octant 1 are missing. Louis and Dave looked at the electronic cables but find nothing. For both detector, all the cfd signals are here.
It certainly comes from the meantimer.
04:15 Call NA electronics expert : Joachim
04:20 We find the problem. It was the input cable of the meantimer 2 which was unplugged just before Joachim called us. Sorry Joachim to wake up you for nothing. Let's go to take production data.
