    Entry number 269864

    keyword=Ready for the production running (Preformatted this time)

    We have made a series of tests to see if the beam spot is OK,
    and checked the T3 rates:

    1.) 2uA beam with raster (4x4mm): T3 = 1.82E2 Hz

    2.) 2uA beam with raster (2x2mm): T3 = 1.73E2 Hz

    3.) 2uA beam with raster (6x6mm): T3 = 1.89E2 Hz

    Since the rates look OK, we have decided to move on and start
    with production running. We have set the prescales to the
    following values:

    LT3 = 5.0E2 Hz => LPS3 = 1
    LT4 = 3.1E1 Hz => LPS4 = 1
    RT1 = 4.0E2 Hz => RPS1 = 1
    RT3 = 3.8E1 Hz => RPS2 = 1

    Unfortunately we can not start with production running just yet,
    because of the problems with the HAPPEX DAQ.
