Ionisation cooling formalism• Exponential decrease in normalised emittance:

• Competition between:– dE/dx [cooling] and MCS [heating]

• Optimum:– Low Z, large X0

– Tight focus

– H2 gives best performance

MICE Hall: Being readied for PRY Installation

• PRY:– Preparation for installation of bases

and restraints on track:• Expect to be installing first set of

“uprights” starting January 2015

Emphasis now shiftingto commissioning

M. A. Palmer | FNAL All Experimenter's Meeting 9

MICE Steps

• Step IV: Study of material, lattice, momentum and emittance to start Q2 CY2015

• Ionization cooling demonstration:– RF Components under test in the

MTA and at Daresbury Lab– Expect that all necessary hardware

will be deployed by Spring 2017– Full demonstration with RF

commences by Summer 2017
