Abstract:

An essential problem for the operation of high current linacs is the control of beam losses due to halo formation. Here we concentrate on an interplay between intrabeam scattering IBS and the incidence of particles which are driven to high amplitudes by resonance with the nonlinear space charge fields of a mismatched beam. For these studies, we developed a particle core-molecular-dynamics PCMD method which suitably joins the time evolution in framework of the envelope equations and a calculation of IBS between pseudo-particles with a renormalized charge. With this technique we investigated continuous KV-beams in a FODO channel. Our first results strongly suggest, that IBS in fact supports the halo formation in a mismatched beam.
