M. A. Palmer | FNAL All Experimenter's Meeting 2
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
and operations …December 15, 2014

Step IV Wrapped with Partial Return Yoke (PRY)
December 15, 2014
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
