Cyclotron superradiance of a moving electron swarm under group synchronization conditions
Ginzburg N. S., Zotova I. V., Sergeev A. S.
In the group synchronization regime, which is realized when the translational velocity of a swarm of electron oscillators is equal to the group velocity of the wave, it becomes possible to increase the growth rate of the superradiance instability and to increase the peak emission power. © 1994 American Institute of Physics.
