Experimental Study of Transition Radiation by Nonrelativistic Electron Bunches on Different Electrodynamic Heterogeneities
Abstract
Electromagnetic transition radiation by coherent nonrelativistic electron bunches on different electrodynamic heterogeneities are experimentally studied in the paper. It was shown that transition radiation spectra considerably effected by rapidity of reorientation of conduction electron movement direction, which can be observed during passage of bunches through diaphragms. Spiral structures were used to enlarge power of transition radiation. The average power for superposed electric and magnetic dipoles more than 10 times exceeded the average power on the system of diaphragms.
