    S.L : T.O : M. Dlamini 3rd : F. Georges

    ================

    00:37; After beam centering done with carbon hole, moved sieves for both HRS arms in started run with Carbon target. Dead time is 0% on left and 1% on right, good.

    00:57 : beam trip.

    01:30 : beam is back !

    01:42 : new beam trip

    02:00 : beam is back

    03:54; Done with Carbon target. Next is LH2

    04:10; target moved from carbon to LH2, loop 1 to start data taking with LH2 target

    04:28; temporary 1 minute beam off 04:34 - 04:35; temporary beam down

    04:50; Changed VDC_HV from -3600 to -3500 RHRS Changed FPP_HV from 1700 to 1800 RHRS 05:11; Runs 1324(LHRS) and 20313(RHS) stopped because beam had not been stable, new runs with same configuration to be started 05:55; Change FPP_HV from 1800 to 1900, RHRS

    06:15; Change FPP_HV from 1900 to 1850, RHRS

    06:34 beam trip

    06:36 beam back

    07:00 beam trip

    07:05 beam is back

    07:09; Called Tech on call to set up appointment to move LHRS to 28 deg.

    07:18; Extension or additions to run plan. Take data with ps1=2, ps2=ps3=ps4=ps5=ps6=10

    07:30; Called MCC for Hall access for Tech. to move LHRS to 28 deg

    07:37; Hall in controlled access

    07:58; Tech on way to change the spectrometer angles

    07:58; Cycled LHRS quads (Q2/Q3) in preparation for next run plan (elastic setting)
