Abstract

This paper starts with an introduction to some elements of physical kinetics relevant to microscopic interactions in gas or plasma systems. The aim is to provide the necessary background for understanding charged particle beams. Emphasis is placed on the important role played by collisions in plasmas. We then give a detailed, albeit non-exhaustive, review of intrabeam scattering (IBS), which consists of the study of diffusion effects caused by multiple Coulomb scattering on charged particle beams, in both the transverse and the longitudinal beam dimensions. Finally, applications to the large hadron collider 7 TeV stored proton beam and the ’Extra Low Energy Antiproton’ (ELENA) 100 keV decelerated antiproton beam are used to illustrate the behaviour of the IBS growth rates, for a high-energy storage ring well above the transition energy and an ultra-low-energy decelerator ring below the transition energy.
