Solenoid Magnetic Field Measurement
Solenoid Magnetic Field Measurement
• MICE solenoid includes 5 coils
• First solenoid expected at FNAL for magnetic field measurements in April
• Measurements to be done with ZipTrack system.

ZipTrack System
• Long metal beam through spectrometer bore– Smaller beam section insertion for MICE– Carriage on beam holds Hall magnetic field probe– Probe in one of six carriage positions
• Beam/carriage location controlled by LabView
Frame with 6 places for Hall probe

MICE Spectrometer and Muon Beam
• Spectrometer dimensions– 20.5 cm bore radius– 3 m long
• Largest MICE beam– 140 MeV/c, 10 mm emittance– 5 cm at 1 RMS
• Map interior of spectrometer– 3 cm grid transverse to beam axis (x, y)– ±15 cm in (x, y)
