Updates from Rakitha,

  • Plastic Shielding Design Update - 3 elog-2942

Updates from Lorenzo

  • Septum pipe magnetic field implementation in PREX geant4 simulation elog 2937

Rakitha, Dustin, Paul, Lorenzo, Nickie, Seamus, Guido, Juliette, KK and Kent


  • Plastic shielding
    • Some concerns for putting plastic in the vacuum include,
      • Thermal damage : we are able to reduce the power down to about 3 W at 100 uA now and Lorenzo is planning to do a analysis to estimate the upper limit of the temperature due to this power for the plastic in vacuum.
      • Out-gassing in vacuum
      • Get more literature on this
  • Magnetic Shielding
    • If we can get TOSCA model from Paul Brindza, Juliette could optimize the magnetic shielding. We have never used TOSCA to do this before.
    • We want to compare the fringe field with added 10 cm at the ends of septum pipe.
    • Then compare magnetic field on/off power in the hall.


  • From Last Meeting
    • Beam parasitic studies

TO DO Lists

  • Organizing a PREX Collaboration meeting (discussed in 02/6 and 02/13 of 2014 meetings)
  • Have a optic calibration run plan (discussed in 01/16/2014 meeting)
  • It would be nice to have real-time viewer for optics studies in commissioning (disussed in 01/16/2014 meeting)
