Abstract
We investigate temperature relaxation processes in bunched and coastin g ion beams at high phase-space densities using the molecular dynamics (MD) simulation technique. A simple model is presented which describe s emittance growth in the framework of extended envelope equations. Th e relaxation rate tau(c)(-1) for the temperature anisotropy is obtaine d from MD simulations. In the regime of strong coupling it decreases p recursing the transition to an ordered beam. Some implications relevan t for beam cooling and beam crystallization are discussed.
