摘要

Abstract

Results of experimental and theoretical investigation of coherent transition radiation from a finite-size target in the prewave zone are presented. The measurements were conducted in sub-terahertz frequency range on the 100-MeV electron beam extracted from LINAC-200 (JINR). A formula for the spectral-angular density of coherent transition radiation is obtained. Results of the simulation of experimental conditions and experimental data are jointly analyzed. Estimation of the bunch length based on experimental data and obtained theoretical model deviates from the expected value.
