Agenda

ReviewofCoordinatesSystems

Minutes

  • Tyler
    • Fixing radiation issues in generator - external target effects were missing, now back in
    • Getting 1 GHz @ 70uA, different from 700 MHz in proposal
    • Need to compare tail cuts and sizes to data
    • Has implemented PREX-I collimator
    • Needs to check septum mistune (believed to be 5% lower than nominal for PREX-I)
  • Ryan
    • Reviewing coordinate systems
    • "Focal plane" has x-dependent rotations from detector system and is different from trasnport system
    • Should be comparing transport to HRStrans results
    • Still not obvious where 3cm L/R x position differences come from - are removed in momentum reconstruction
      • Will track down
      • Will develop translation between fp reconstruction matrices and transport equivalents
  • Eric will be working on Moller spectrometer simulations with Sanghwa
