MICE Stages by Alain Blondel

- 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 knobs necessary to draw Emittance vs transmission curve. Measure emittance
These are mostly questions for beam design and matching to and within solenoid.

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
