Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

This paper presents the theoretical results of a CW W-band (88-102 GHz), 10 kW Gyrotron Backward-Wave Oscillator (Gyro-BWO). A mildly relativistic, axis-encircling electron beam from a cusp gun has been designed to drive an interaction based on the Cyclotron Resonance Maser (CRM) instability in a cavity with a helically corrugated inner surface.
