Beam Physics Seminar
Recent developments in particle accelerators make it possible to
conceive of intense neutrino beams based on the decay of a very
intense beam of stored muons: a Neutrino Factory. A conceptual
design of a muon acceleration scheme based on recirculating
superconducting linacs is proposed. Acceleration of a muon beam
is a challenging task because of a large source phase space and
short species lifetime. In the presented scenario, acceleration
starts after ionization cooling at 210 MeV/c and proceeds to 20
GeV, where the beam is injected into a neutrino factory storage
ring. The key technical issues are addressed; such as: the choice
of acceleration technology (superconducting versus normal conducting)
and the choice of RF frequency, and finally, implementation of
the overall acceleration scheme: capture, acceleration, transport
and preservation of large phase space of fast decaying species.
Beam transport issues for large-momentum-spread beams are
accommodated by appropriate lattice design choices. Presented
proof-of-principle optics for all arcs with the horizontal
separation of multi-pass beams has been tested via 6-D multi-particle
tracking. The proposed lattics design is further optimized with
a sextupole correction scheme to suppress chromatic effects
contributing to emittance dilution.
