RADIATION BY RELATIVISTIC ELECTRONS IN THIN TARGETS AND AT COLLISIONS WITH SHORT BUNCHES OF RELATIVISTIC PARTICLES

摘要

The process of radiation at collision of relativistic electron with short and long bunch of relativistic particles is considered. The analogy between this process and the process of radiation by relativistic electrons in oriented crystals is mentioned. Conditions, under which the coherent effect in radiation and the effect of suppression of coherent radiation take place, are obtained. Physical causes for arising of these effects are discussed.
