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.
