Summary on Grant Application Form
Relativistic, fast wave, generators of high power mm-waves need HV, eg >5001V, pulses to provide intense electron beams. The proposed programme aims to design and apply HV, ns pulsers at PRFs and efficiencies hitherto unobtained in the UK. A unique feature is the application of high PRF, energy efficient, adaptive HV pulse generators to intense pulsed microwave production. This proposal builds upon the recent research results obtained in both of our Departments. Our research on pulsed power and switching characteristics combined with recent results on the nonlinear electron cyclotron maser load behaviour should enable this collaboration between our two Departments to make timely and internationally significant advances. For continuous operation the pulser will be designed to provide a true PRF of >1kHz. To investigate much higher PRFs a double pulser will be designed and constructed to allow pairs of pulses to be generated and applied to an electron cyclotron maser. By controlling the delay between the two pulses it will be possible to simulate 1mhz, or higher, pseudo PRFs. Advanced gas switching, compact generator technology and novel pulse forming networks will be used. The pulser-generator system will be designed as an actively load-adaptive circuit. The programme will incorporate measurements of the mm-wave pulse characteristics. This work while relevant to pulsed microwave production, has a much wider applicability to repetitively pulsed microwave production, has a wider applicability to repetitively pulsed high voltage systems, eg lasers, e-beams, x-rays, ion beams etc.
