    keyword=Day Shift Summary

    8:00 Start of day shift. We are in the middle of Kinimatic 5.16 with teh beam half-wave palte OUT.

    Kin. 5.16
    Right arm momentum = 1.276, angle=12.5 deg.
    Left arm momentum = 3.17, angle=18 deg.
    Septum Current = 118 A

    Raster on
    Beam Current = 3.6 amp

    Right arm run
    Time Run Num. Target PS1 PS2 beam lamba/2 target lamba/2 Events
    8:00-8:15 2989 3He(0 deg) 2 2 OUT OUT 3M
    8:17-8:33 2990 3He(0 deg) 2 2 OUT OUT 3M
    8:35-8:41 2991 3He(0 deg) 2 2 OUT OUT 1.3M
    8:52-9:09 2992 3He(270 deg) 2 2 OUT OUT 3M
    9:11-9:15 2993 3He(270 deg) 2 2 OUT OUT 0.7M


    8:42 Request MCC to remove the beam so that we can roatate the holding field to 270 deg.
    8:50 Request MCC to return the beam.
    9:00 The left arm DAQ has a problem, see message: 107878.
    9:15 Request MCC to remove beam and mask the target.
    9:16 Began the kinimatic change to 5.17, we have set the magnet momentum and changed the septum current.


    Kin. 5.17
    Right arm momentum = 1.185, angle=12.5 deg.
    Left arm momentum = 3.17, angle=18 deg.
    Septum Current = 109.7 A

    Raster on
    Beam Current = 3.8 amp

    Right arm run
    Time Run Num. Target PS1 PS2 beam lamba/2 target lamba/2 Events
    9:37-9:47 2994 Reference-Empty 1 1 OUT OUT 1.97M
    9:50-10:01 2995 Reference-N2 13 13 OUT OUT 1.73M
    13:55-14:19 2996 3He(0 deg) 2 2 OUT OUT 3M
    14:20-14:36 2997 3He(0 deg) 2 2 OUT OUT 3M
    14:37-14:52 2998 3He(0 deg) 2 2 OUT OUT 3M
    14:53-15:00 2999 3He(0 deg) 2 2 OUT OUT 1.61M



    10:00 Beam lost for a tour, estimate for beam return 12:00.
    10:02 Request MCC mask the target, so that we can move to Pol 3He position.

    10:22 We have done an NMR measurement which gives a target P=39.75%.

    11:40 Rob called and he rebooted the left arm system, but he gets another boot error. He believes it is a bad module.

    11:44 Bryan M. says that the Parity DAQ is working.

    11:58 I just talked to the MCC, and they said that beam studies will "probably" be extanded until 13:00.

    12:16 Rob has replaced the card, and Bob M. is here to help him. They sound confident that they have the left arm DAQ problem fixed.

    12:59 MCC called, and they have a problem which will delay beam for a little while.

    13:19 The left DAQ problem has not been fixed. It has been decided to work on it tomorrow during the energy change.

    13:27 We talked with MCC and they will get us into Beam Permit.

    13:29 Bob and Rob fixed the VDC problem with teh left arm. We will not run the left arm DAQ.

    13:33 Beam Permit.

    13:38 MCC called beam in 10 minutes.

    13:54 We request for 3.8uA and prescale by 2.

    14:12 Bleedthrough = 2.22%, with a slit position of 35 and the attenuator at 317.

    14:46 MCC called and theya re haveing problems with the vertical fast feedback system. During our next kinimatic switch they will go in to look at it.

    14:53 MCC called and beam will go away at 3pm for 1/2 hour. They can do the kinimatic switch at the same time.

    15:00 Beam gone.

    15:40 Rebooted adaqlr3.

    16:00 Shift over.
