Abstract :
A method of decreasing the beam emittance is considered using intrabeam Coulomb scattering of particles during the processes of beam formation and acceleration. The necessary conditions for efficient heat transfer from transverse degrees of freedom into longitudinal ones are formulated, and the principal limitations on the rate of cooling and achievable temperature are established. An example of the self-cooling is given for the case of a beam formed and accelerated in the space charge regime and in the presence of an external accompanying magnetic field.<>
