MOLECULAR-DYNAMICS SIMULATIONS OF STRONGLY COUPLED PARTICLE BEAMS

We investigate the dynamics of intense space-charge-dominated heavy-io n beams. Our main interest lies in the various processes causing emitt ance changes. We extend the well-known envelope equations for periodic quadrupole channels by introducing a dynamics for the emittances. The additional equations account for intrabeam scattering. The parameter of the model, a relaxation rate, is discussed over a wide range of bea m parameters. A generalization of the envelope equations to the case o f storage rings, where bending magnets and thus dispersion are present , is also given. Finally, we present first results concerning intrabea m scattering effects in space-charge-dominated beams in storage rings.
