The Strathprints institutional repository (https://strathprints.strath.ac.uk) is a digital archive of University of Strathclyde research outputs. It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. Abstract-Superradiance (SR) of electron bunches can be considered an effective method of production of ultrashort electromagnetic pulses. Different types of SR associated with different mechanisms (cyclotron, Cherenkov, and bremsstrahlung) of stimulated emission are observed experimentally in the millimeter and centimeter wavelength bands. Progress in this research has enabled a new type of generator to be created capable of generating unique short (under 200-300 ps) electromagnetic pulses at super high peak powers exceeding 1 GW in the millimeter and 3 GW in the centimeter waveband. Some new methods for further increasing of the SR pulse peak power along with the promotion of such sources to higher frequency bands are discussed. These new methods include phase synchronization of several SR pulse generators, the amplification of an SR pulse during its propagation along a quasi-stationary electron beam and nonlinear compression in the process of induced selftransparency.

“…Actually, even when the oscillator operates under the conditions that the e-beam and the counter electromagnetic wave are off cyclotron resonance, a rather strong guide magnetic field is required (∼2 T). Therefore, as distinct from the dc magnetic systems of X-band BWOs [29], [30], the radius of the dc solenoid winding of a K a-band oscillator [31] is comparable with the axial length of the beam-wave interaction space; that is, small-scale profiling [varying r b (z)] is difficult to perform. It is much simpler to obtain the required magnetic line topology using a magnetic pulse generator with a properly thin solenoid [32], [33].…”

Variations in the transient time and in the microwave pulse duration and peak power have been demonstrated for a relativistic subgigawatt K a-band backwardwave oscillator (BWO) with the slow-wave structure geometry, the accelerating voltage, and the electron beam current remained unchanged. This was done taking into account that the BWO operation mode depends on the starting-current-tobeam-current ratio. Efficient variation of the starting current was attained by changing the beam path in view of a significant difference between the times of the guide pulsed magnetic field diffusion into the electron injection region and beam-wave interaction space.

Report demonstrates the results of coherent power summation from two nanosecond-width relativistic Kaband BWOs with the peak power above 200 MW in each channel. A peculiar feature of the experiment was in supplying the explosive electron emission cathodes with ultimate-stable split voltage pulse from an all-solid-state SOS modulator. Enhanced rate of the voltage rise provided stable emission of electron beams and minimized standard deviation of the microwaves phases between channels in the time scale down to 0.5 ps.
