Description

Channeling effect in crystals is a very convenient method for charged particle bunches manipulation. In particular, this phenomena can be used for charged particle beams shaping, collimation and extraction. As known, considerable radiation energy losses of channeled particles (due to channeling radiation) can be used as a novel method of beam cooling. However, during such interaction of charged particles with crystals inelastic processes take place causing channeled particles to leave channels (dechanneling) and other particles (as a result of nuclear reactions) to be born. Charged particle beams channeling in laser field has some advantages over crystal channeling due to strong suppression of inelastic processes. Besides, potential channels formed by combined laser fields have a number of features helping to adjust channels structure (depth, width etc). In this work we describe process of muons channeling in laser channels. Radiation losses for charged particles are taken into account and both analytical and numerical descriptions of radiation cooling are presented. Also a comparative analysis for the efficiency of muons cooling by laser and crystal fields is given paying attention to their relative advantages and drawbacks.
