The aim of the research programme is to study new methods of producing high power ultra-short pulses of millimetre wave electromagnetic radiation through non-linear interaction of short radiation pulses with relativistic electron beams traversing free-electron maser (FEM) like structures.Brief high power microwave pulses of 6-20 cycle duration, from a dedicated high power microwave source, will be amplified in a high power FEM-like swept-gain amplifier to reach the strongly non-linear superradiant (SR) regime where the pulses are simultaneously compressed and amplified with high efficiencies. This regime will be examined and compared with the direct amplification of single to sub-cycle (strictly quasi-unipolar) mm-waves pulses. The influence of slippage between the evolving SR microwave and pulse and electrons will be examined using the oscillator-amplifier configuration.Tunability and scalability of ultra-short pulse propagation in the microwave regime will be evaluated.Intense radiation pulses as short as one half of a cyclein the millimetre wavelength range are valuable research tools in a wide range of academic and industrial domains e.g. materials processing, physics, pollution control, chemistry, biology, engineering, information technology and medicine.
