Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Presented in this paper are the results of a 10kW W-Band Gyro-BWO based on a helically corrugated interaction region and novel cusp electron gun. Microwave measurements of the helically corrugated interaction region are shown to give a low loss of similar to 1dB over the frequency region of interest (84-104 GHz). The measured dispersion was found in good agreement with the analytically calculated and numerically simulated dispersions. The design and simulation results of the cusp electron gun of the Gyro-BWO device are given in this paper.
