1. Solenoid Magnetic Field Measurement

2. MICE solenoid includes 5 coils First solenoid expected at FNAL for magnetic field measurements in April Measurements to be done with ZipTrack system. Terry Hart, NFMC CM, March 18, 2008 23 of 29

3. 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

4. Frame with 6 places for Hall probe 1 2 3 4 5 6 Mike Roman, Terry Hart with smaller beam insert for MICE spectrometer ZipTrack system

5. 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)
