Dynamics and Cooling of Modulated Bunches in Bend

Abstract

The influence of the space charge fields on the dynamics of the particles of the bunch, which is moved in a bending magnet is calculated. It is shown, that such influence of the Coulomb force on the energy of the particles of a modulated beam causes in the decreasing of the bunch energy spread during the compression due to energy deviation along the compressed bunch, i.e. bunch cooling. The necessary conditions of the maximal cooling are found. The attainable ordering of the bunch is investigated.
