1. MICE target stator: measurements & modelling Ben Shepherd MICE target workshop 13 May 2011

2. Talk Outline Magnetic measurements of target stator – setup & alignment – measurement technique – position of centre Modelling of stator & magnets – 2d model – 3d model

3. Measurement Setup Stator set up on magnet measurement bench at Daresbury Aligned to ~100µm in 1.8m Measure field using 3-axis Hall probe, movable in 3 directions bench telescope zxy  Hall probe

4. Longitudinal field map B0, B1: transverse field B2: longitudinal field To find solenoid axis: minimum in B2, zero in B0, B1

5. Results
