the (e,P) matrix for the MICE Beamline 

 

 

 

Legenda:
  • alfa,beta: Twiss parameters at the diffuser US face
  • t: diffuser thickness / Bsol: DK solenoid field / Btrk: spectrometer field
  • P0: PI-momentum at production point
  • Psol: MU-momentum at the exit of DKsol (before GVA1) / Pdiff: MU-momentum at the diffuser US face
