two highlights from PAC07
the other way of cooling …
1.the beamlet concept
2.MANX cooling channel
m. apollonio
beamlets
http://pac07.org/proceedings/PAPERS/THPMN102.PDF
Leading idea:
1. use a pencil beam at high intensity
2. no single particle approach
3. requires less precise detectors
4. cover the phase space
5. Scintillating fibers to commission
beamline and measure cooling
beamline design
muon / pion separation: electrostatic separator
Muon beamline @ MuCool Test Area (FermiLab)
mu-yield 2 10-6 in [200-250] MeV/c range
104 muons / linac pulse
75 mm mrad per pencil beam

Prove 6D mu-cooling
HCC (helical cooling channel), NO RFs
Intense nu-fact and high lumi. mu-colliders
170 MeV/c
300 MeV/c

LHe: cooler + cryo
B field varies to compensate for
momentum reduction
