6  - STEP I STEP II STEP II.V Insert absorber (solid) between the two halves and measure Pt & E distribution and emittance growth STEP II.VI Split tracker in two parts and measure against each other (systematics) Establish beam match andwether we have all knobsnecessary to drawEmittance vs transmissioncurve. Measure emittance These are mostly questions for beam design and matching to and within solenoid. MICE Additional Stages by Alain

7 STEP V STEP V.0 Shorter, less expensive, no coupling coil, (very limited optics flexibility) does this work in flip, RFoFo, non flip modes? These are mostly optics questions MICE Additional Stages by Alain
