Description

The results of an experimental study of the spectral distribution of coherent Cherenkov radiation from a pair of electron bunches at the AREAL Accelerator are presented. As a target, a cylindrical Teflon resonator is used. Coherent effects were studied depending on the distance between the bunches, which varied from 2 to 11 ps. Radiation was recorded using QOD (Broadband Quasi- Optical Detector based Schottky Barrier Diode), designed for frequencies ranging from 30 to 1000 GHz. The obtained results were compared with previous experimental data and theoretical estimates.
The work was partially supported by the Science Committee of RA, in the frames of the research project № 21AG-1C069.
