A possibility to use a ring cooler for the MUCOOL experiment is considered. The cooler is a ring accelerator of about 37 m in circumference consisting of 8 dipole magnets, 4 short solenoids with a field flip of ±2.5 T, and 4 long solenoids with adiabatic field 2 - 5 T. The 201.25 MHz linacs provide accelerating gradient 15 MV/min in the long straight sections. Four 1.3 m long liquid hydrogen absorbers are put between the linacs for transverse cooling, and LiH wedge absorbers in the short SS are used for the emittance exchange. To simplify the injection problem, π-μ-production on an internal target is considered as an option for the MUCOOL experiment.
