Abstract :
A transport equation has been derived in terms of the longitudinal action variable to describe the time evolution of the longitudinal density distribution of a bunched hadron beam in the presence of intrabeam scattering and stochastic cooling. A computer program has been developed to numerically solve this equation. Both beam loss and bunch-shape evolution have been investigated for the /sup 197/Au/sup 79+/ beams during the 10-h storage in the Relativistic Heavy Ion Collider (RHIC) currently under construction at the Brookhaven National Laboratory.<>
