EMU tracking
2Telsa magnetic field, big variation 100um
Cathode resolution, cm Anode resolution
Radial magnetic field

Simple model
Multiple scattering

Magnetic Bending (with high momentum
approximation)
600mm Iron 2Tesla
Magnetic effect is 34 times of multiple
scattering effect, We expect 30 momentum
resolution.
The muon track reconstruction can reach
101000GeV/c
Energy loss 1GeV, negligible

Summary

• Work is just starting, need calibration, magetic
  field parameters,
• alignment ?100um position resolution
• 30 momentum resolution
• Reaching 101000 GeV/c
• ME1 position for global muon reconstruction
