    Tests start in order to check coincidence trigger at 4 uA.

    2:50 Test ended. Beam back at 1.5 uA

    3:15 Hall C starts large charge asymmetry run.

    4:20 Beam OFF to perform a pedestal run.

    4:30 Beam ON again.

    4:55 Beam OFF to perform a new pedestal run.

    5:00 Beam On again

    5:07 Hall C large charge asymmetry run stops.

    5:25 Beam current rised from 1.5 to 2 uA
