A conceptual lattice design for a muon accelerator based on recirculating linacs [1] is presented here.
The challenge of accelerating and transporting a large phase space of short-lived muons is answered here
by presenting a proof-of-principle lattice design for a recirculating linac accelerator. It is the
centerpiece of a chain of accelerators consisting of a 3 GeV linac and two consecutive recirculating
linear accelerators, which facilitates acceleration starting after ionization cooling at 190 MeV/c and
proceeding to 50 GeV. Beam transport issues for large-momentum-spread beams are accommodated by appropriate
lattice design choices. The resulting arc optics is further optimized with a sextupole correction to
suppress chromatic effects contributing to emittance dilution. The presented proof-of-principle design
of the arc optics with horizontal separation of multi-pass beams can be extended for all passes in both
recirculating linacs.
