    08:40 : HRSH dipole work in Hall done, start ramping up the magnets
    09:15 : HRSH-Q2 trip, new controlled access
    09:40 : MCC called: Plant services fixed the temperature problem which
    caused the fluctuations which prevented the ARC measurement last night.
    09:50 : Hall-A beam permit
    11:45 : HRSH dipole ready

    12:35: MCC informed that they need a control access to Hall A to check the ion chamber.

    13:00 Change the target to 12C
    13:15 MCC is having problems with the fast feedback. They can only send 25uA
    beam to hall A. MCC is contacting the experts to fix this problem.
    13:25 MCC told us they found the beam problem was due to the two beams
    in the Hall A. Need 30min to fix it.
    14:25 MCC is still trying to fix the fast feedback problem.
    14:50 MCC fixed the BCM problem. Still trying to fix the fast feedback problem.
    15:55 Change the H-Arm 6ms coll. to sieve slit.
