Design of the Superconducting RFQ for PIAVE Linac (NUCLEAR SCIENCE RESEARCH FACILITY?Particle and Photon Beams)

Three-dimensional (3D) laser cooling method of fast stored ion beams based on linear coupling mechanism is explored. We employ the tracking code "SAD", showing that resonant coupling remarkably enhances transverse cooling rates. Molecular dynamics (MD) code "SOLID" is also employed to study the effect of space charges and the possibility of beam crystallization.
