| contents | The standard approach in the conventional theory of intrabeam scattering (IBS) is based on the analysis of binary Coulomb collisions of charged particles in the beam. This picture is only partially true: in reality, a given particle collides simultaneously with many partners and a more rigorous treatment should take this collective aspect of the collisions into account. A framework for such treatment has been known in plasma physics since beginning of the 1960s. In this work, we will show how it can be applied to IBS in relativistic beams for a particular problem of the growth of the beam energy spread. A preliminary conclusion of this work is that the conventional IBS theory might underestimate the effects of long-range correlations in Coulomb collisions in the beam. |
