    keyword=shift summary

    16:00 - mcc trying to narrow the beam size to 200u at our harp
    17:35 - mcc says they can't get a better spot size than 220u x 250u
    17:41 r3609 start coda run
    harp scan is not working properly - 1H03A does not show a green trace.
    harp run 1957 saved with 1H03B red/green trace and 1H03A only red trace.
    go to 5uA to see if harp scan will work - the 1H03A is still red only
    18:15 Contacted Arun about the harp problem. He told us that only MCC can fix this, if it is a speed problem and that they may need to call in a software person. We called Rob to contact mcc about this.
    18:15 put in BeO to see the spot - beam is lost due to an RF trip. MCC estimates 1/2 hr beam off

    18:45 saw spot on BeO, asked for the beam off to move to C
    18:52 start run 3610 p=1.612 (-4%), need to set the ps factors

    19:05 start run 3612 with raster on
    spot size looks to be the same with spott++ with raster on or raster off.
    19:11 start run 3613 raster off
    19:30 mcc will do harp scan - It seems we can not do optics runs with a beam spot width of this size ( 1000u).
    mcc says the beam spot is 300ux300u at 1H0B3
    we decide to go ahead and measure the delta scan.
    20:04 r3616 start, -4% delta, raster off
    20:15 start lowering momentum to 1.5965
    20:39 r3618, start p = 1.5965
    20:46 r3618, stop at 400K
    21:05 r3619 start p=1.581, raster off
    21:11 r3619 stop
    21:15 r3620 start p=1.581, raster on, mcc says it is 2mm x 2mm,
    spott++ says 2 x 2 also
    21:26 r3620 end because the right septum current had dropped out, with no alarm from alarm handler!
    recover right septum control - see feuerbach comment
    21:52 start r3621, p=1.581,raster 2x2, recovered right septum
    22:02 start r3622, p=1.581, raster 6x6 according to mcc, but it looks like 2x2 according to spot++. It is larger than r3621.
    22:11 r 3622 stop
    22:13 turn off raster and go to p=1.5655
    22:24 start r3623, p=1.5655, raster off, accidentally left septum at 146.37A which corresponds to p=1.581! We decide to go forward with delta scan.
    22:46 start r3624, p=1.550, septa=143.50A, raster off
    22:53 r3624 end
    22:56 r3625 start, p=1.550, septa=143.5A, raster on 2x2
    23:03 r3625 stop
    23:05 r3626 start, p=1.550, septa=143.50, raster on 6mmx6mm
    23:12 r3626 stop
    23:27 r3627 start, p=1.5345, septa = 141.50A,142.06A, raster off
    23:34 r3627 stop
    23:47 r3628 start p=1.519, septa=141.00A, 140.50A, raster off
    23:55 r3628 stop
    23:59 r3629 start p=1.519, septa=140.5, raster = 2x2
