Paolo, Ao volunteer to watch data

Rogers:
  • Should require 5 space points per tracker on the PRStraightTrack
  • Should require 15 track points per tracker
  • Add TKU radial plot
Paolo:
  • Note first slide - dependence between TOF0/TOF1 triggers is inverted
  • Second slide - lots of worry about statistical noise; hysteresis? beamline stability?
  • Check the reference runs for consistency
  • Check the alarm handler settings - where is the alarm limit for the conventional magnets; are CDB set values consistent with alarm limit
Tanaz:
  • Still see big spike at the M2D coil
  • Remove M2D
  • Remove trackers
    Note that it is consistent with z position of transmission loss; nonetheless not improved
