SIMULATION STUDY OF THREE-DIMENSIONAL LASER COOLING SCHEMES FOR FAST STORED BEAMS

Molecular dynamics (MD) approach is employed to study laser cooling of fast circulating beams in a storage ring. We compare several three-dimensional (3D) cooling methods, examining achievable minimum beam temperature. In particular, the stress is put upon the three coupling schemes, i.e. the dispersion-coupling scheme, the coupling-cavity scheme, and the tapered cooling scheme. We show that beam temperatures much lower than the currently achievable level could be reached with these schemes.
