Pion to Muon Decay Channel
•Challenge:
high emittance of target pions
–Currently
come from a 20cm tantalum rod
•Solution:
superconducting solenoids
–S/C
enables a high focussing field
–Larger
aperture than quadrupoles
•Basic
lattice uses regular ~4T focussing
–Initial
smaller 20T solenoid around target
–30m
length = 2.5 pion decay times at 200MeV
