【 摘 要 】

Nowadays the achievements in accelerator physics allows us to operate with evergrowing energy of the particles beams. However, the increase of the beam energy requests new issues to be resolved. For instance, it becomes necessary to develop new techniques for beam diagnostics. One of the promising solutions for beam diagnostics is based on diffraction radiation (DR). In this work similar to the methods of bunch length measurement based on transition radiation, the longitudinal size of a bunch is retrieved from the dependence of the DR intensity on the wavelength of radiation. Such dependence is expressed by so-called form-factor, which in turn depends on the beam parameters. Influence of the beam divergence on the form-factor of a beam has been examined in this work.
