  We discuss the various schemes to use ring coolers for 6D cooling for Mu+Mu- colliders. The earliest successful cooler used dipoles and quadrupoles and a high dispersion low beta region. This was also proposed in the form of solenoids. Recently, there have been many new ideas. The simplest is to use a simple dipole ring with high-pressure gas absorber or Li hydride. We show the results of simulations and compare with the results for other cooler schemes.

  A curved Lithium lens ring model can provide the emittance exchange mechanism in obtaining the muon 6 dimensional phase space cooling. With straight Lithium lenses in a muon cooling ring, only transverse phase space cooling has been demonstrated. We demonstrate the 6 dimensional phase space cooling with various parameters of a muon cooling ring in tracking simulation.
