SIMULATION OF ELECTRON COOLING AND INTRABEAM SCATTERING PROCESSES OF A HEAVY-ION BEAM IN HIRFL-CSR

This paper is devoted to the simulation of electron cooling and intrab eam scattering processes of a heavy ion beam in the proposed HIRFL-CSR , according to the analytical cooling force formulae and the intrabeam scattering growth rate expressions. Some important effects like the b etatron and synchrotron oscillations, and space charge effect of the e lectron beam have been considered. Time evolution of beam emittances a nd momentum spread under joint action of the electron cooling and intr abeam scattering are shown. The dependence of ion beam properties in e quilibrium on the number of particles and the electron current are pre sented.
