Abstract:
The form factor of a hollow electron beam for transition radiation has been calculated. It has been shown that the characteristics of coherent radiation are significantly different for conventional solid and hollow beams. Numerical estimates have been obtained for terahertz radiation frequencies and relativistic energies of el-ectrons.
This study was supported by the Russian Science Foundation (project no. 21-72-00113, D. Sergeeva, Sections 3 and 4) and in part by the Ministry of Science and Higher Education of the Russian Federation (project no. FZWG-2020-0032 (2019-1569), competitive part of the state assignment for the organization and development of laboratories, A. Tishchenko, Sections 1 and 2).
