Phone Call 2015-02-26

Analysis phone call, 15:00 GMT, Thursday 26th February 2015.

Phone Details


  • ACTION (Pasternak/Rogers): determine magnetic settings routine - do we imagine "equivalent coil"? Implement iron in MAUS? Run everything through OPERA?
  • ACTION (Pasternak/Rogers): determine standard magnetic settings for commissioning e.g. magnet currents for 420 mm beta in solenoid mode
  • ACTION (Pasternak/Rogers): determine standard beamline settings
  • ACTION (Rogers): Xboa specification document
    • In preparation - not ready for public yet
  • ACTION (Rogers): Bring in Dobbs MAUS analysis framework to xboa?
  • ACTION (Rogers/Rajaram/Blackmore): Official plots and publications pages
  • ACTION (Uchida): Organise field mapping of the iron for trackers alignment check
  • ACTION (Rogers): Set the desired number of good muons following trigger revamp/what are the aims/scope?
  • ACTION (Rogers): Redo trigger/data rate analysis with optimised beamline
  • ACTION (Rogers): Redo trigger/data rate analysis with better transverse cut
  • ACTION (Rogers): Check momentum spread/momentum cut effects (what happens to the beam if we make a bigger momentum spread)
  • ACTION (Rogers): Look at TOF2 trigger effect on analysis (e.g. what are the consequences if we trigger downstream of the experiment on rate?
  • ACTION (Rogers): Determine effect of increased dip depth in ISIS (e.g. what are the consequences if we take more particles into the experiment? does it help?)

RLSR/MPB Actions

  • ACTION (Rajaram/Rogers): Investigate as a matter of urgency technical means to optimize the trigger efficiency for ‘good’ muons, and remove dataflow bottlenecks before the Step IV run.
  • ACTION (Rogers): Plan and execute a blind ‘physics analysis challenge’ in order to ensure the readiness of the whole collaboration for data analysis, early in 2015.
  • ACTION (Pasternak): Ensure optimization of the beamline settings in order to preserve matching at the entrance of the ionization channel and potentially increase the number of ‘good’ muons, during the Step IV run.
  • ACTION (Boyd): Include a set of measurements in a configuration with large beta functions in Step IV data taking, in order to validate the muon tracking tools for trajectories with large displacements passing through nonlinear magnetic fields, and to explore the size of the cooling system apertures.
