Achromatic Cooling Channel with Li Lenses
V.Balbekov, Fermilab
A linear cooling channel with Li lenses, solenoids, and 201 MHz RF cavities
is considered. A special lattice design is used to minimize chromatic
aberrations by suppression of several betatron resonances. Transverse
emittance of muon beam decreases from 2 mm to 0.5 mm at the channel
of about 110 m length. Longitudinal heating is modest, therefore transmission
of the channel is rather high: 96\% without decay and 90\% with decay.
Minimal beam emittance achievable by similar channel estimated as about
0.25 mm at surface field of Li lenses 10 T.
