2 BeamLines Availability April, 22 2009UKNF09 - Lancaster Reference Beam Line – muon (e,P=207 MeV/c) Beamlines for initial/calibration studies: from (a) with local momentum rescaling of the magnets [ with / without solenoid ] (infact we used the one with no DKsol for the aformetntioned reasons) electron (@150 MeV/c) used for TOF calibration pions (@ 300 MeV/c) 1st muons seen protons (@480 MeV/c) 1st estimate of primary intensity

4 TOF Analysis to determine Beam Parameters: - x / y - mittance - x / y, x / y see Mark’s Talk BeamLines Analysis April, 22 2009UKNF09 - Lancaster

10 recalculated e=6mm rad, P=207 new tuning e=10 mm rad, P=207 investigate case e=3 mm rad P=207 (does not converge) PLAN: fix P=140/240 and cover the remaining empty elements ???

11
11 - so far beamline used for initial studies & calibrations - no solenoid reduced amount of secondaries - studies to complete the (e,P) matrix (BL tuning for all possible configurations of MICE) -waiting for DKsol (1) and check predictions vs measurements (1) & tgt Summary
