    00:00 Shift started with hall still at controlled access status due to target motion problem
    04:30 The problem on target motion is not solved too; start beam tuning with BeO target to perform test runs with Cherenkov HV ON
    05:00 Beam tuned, turn on BB Cherenkov HV, and ready to start test runs
    05:16 Start run 3617: BB Cherenkov HV ON test run, 0.5 microA
    05:46 Start run 3618: BB Cherenkov HV ON test run, 0.2 microA
    05:59 Start run 3619: BB Cherenkov HV ON test run, 0.2 microA
    06:20 Stop run 3619 due to beam lost
    06:32 Start run 3620: BB Cherenkov HV ON test run, 0.1 microA
    07:15 Beam problem, stop the test runs
    07:25 Pam from software group works to solve the target motion problem; beam masked
    07:34 Beam problem solved, but Pam continue to work on target motion problem
    07:39 BB Cherenkov HV turn OFF
    07:45 Pam have fixed the target motion problem
    07:48 BB Cherenkov HV trun ON, moving target to BeO target
    07:52 Start run 3622 BB Cherenkov HV ON test run, 0.5 microA
    07:59 Stop run 3622 to adjust the beam position on BeO target because is not centered
    08:02 Start run 3623, beam tuned; BB Cherenkov HV ON test run, 0.5 microA
