    keyword=beam trip problem solved, raster at 10x10 setting

    
    Problem of beam trips seems to have been resolved by a routine recalibration of 
    the fast feedback system... maybe the ioc reboot done sometime before plays 
    into this as well.
    
    Raster has been left at 10x10, because the detector/lumi widths seem to be ok, 
    only 3650 ppm combined detector width, lumi combos at 950 ppm. We are back to 
    dithering and otherwise running production as normal.
