10% cooling of 200 MeV muons requires ~ 20 MV of RF single particle measurements =>

measurement precision can be as good as out/ in ) = 10-3

201 MHz RF cavities

Liquid H2 absorbersor LiH ?

SC Solenoids;Spectrometer, focus pair, compensation coil

new drawing needed with new magnetic configand matching coils in!

Pictures explaining the operation of MICEand the quantities to be measured

was done with 88 MHz, PATH, no spectro match, etc… -> need actual MICE

-> Palmer, (ICOOL)

Lombardi(PATH)one of the two is enough

spectrometer performance by P. Janot. No noise, inefficiencies, ad hoc fortran code.

do this with ‘official GEANT4’ + Bkg, efficiency, etc.. One detector choice is enough!

+ simulations in the particle ID (downstream)

Systematic effects…

in cooling:-- need for magnetic measurements was identified (see JM Rey)

justification for specs (10-3 measurements?) is missing

-- thickness of absorbers (how will this be measured)

-- RF field monitoring ? in measurement-- tracking errors, tof systematics…

-- others?
