ABSTRACT
A breadboard model is created of free electron laser with homogeneous guiding magnetic field. A theoretical model allowing to explain a number of properties of such device is suggested. It is demonstrated that a resonance amplification of signal power in the range of nonrelativistic and slightly relativistic energies of electrons is in principle possible. Resonance generation conditions connecting initial velocity of electrons with homogeneous guiding magnetic field value are analytically obtained. Comparison of calculation results with results of numerical simulation of electron trajectories has shown a satisfactory fir. Preliminary results are presented of experimental investigations, and a number of resonances in total radiation power predicted by theory are revealed.
