    16:00 Still waiting for MCC to allow controled access to move the HRS.
    16:45 At the request of MCC we conducted a HARP scan.
    the harp's run number is 2321.
    /DATA/arc/ARC/scan_2321.data
    Results are:
    Scanner 5: H.sigma=174um V.sigma=160um
    Scanner 6: H.sigma=165um V.sigma=121um
    17:20 Hall access, got Ed's premission to move LHRS
    17:25 moving LHRS to 22.41
    17:30 MCC says beam is ready.
    17:55 Took another HARP scan with 5uA.run number 2322 results:
    Scanner 5: H.sigma=157um V.sigma=111um
    Scanner 6: H.sigma=147um V.sigma=119um
    18:04 15uA - T3 is 600Hz at -4,2
    15uA - T3 is 3KHz at -6,5
    15ua - T3 is 600Hz at -2,5
    15uA - T3 is 600Hz at -2,1
    15uA - T3 is 900Hz at -6,-1
    15uA - T3 is 3.6KHz at -7,2
    15uA - T3 is 22KHz at 2,2
    15uA - T3 is 600Hz at -3,2
    15uA - T3 is 640Hz at -5,5
    15uA - T3 is 600Hz at -1,5
    15uA - T3 is 580Hz at -1,-1
    15uA - T3 is 600Hz at -5,-1
    15uA - T3 is 600Hz at -3,2
    18:25 decided to go with beam center at -3,2 we're getting T3=600Hz at 15uA. Raster size is 4X6.
    20:30 MCC droped us to 47uA on run No1188 to do some tests.
    22:05 taking a run with pulser only,to investigate the strange raster distribution - all prescales set to 65535 except T8=3.
    22:25 Beam center moved to -2.5,2 and then to -3.5,2 for spot runs
    22:35 Beam center moved to -3,2, this solved the strange raste distribution and so we'll take a 2hr production run with this beam position.
    23:50 MCC droped us to 35uA, to run tests of the last hour beam trips.
    23:55, shift end, Production run 1193 still running on Pb, beam has not been stable for the last 20min.
