Description

This item was taken from the IEEE Conference ' Generation of powerful ultrashort microwave pulses based on superradiance of subnanosecond high-current electron bunches ' The first experimental results of the observation of superradiance from a single subnanosecond high current electron bunch are presented. Superradiance was associated with different varieties of stimulated emission (Cherenkov, bremsstrahlung, cyclotron, etc.). Ka band microwave pulses with a unique short duration (300 ps) and peak power up to 60 MW have been obtained. A repetition rate mode up to 25 pps is realized.
