    Abstract

    We report the results from a coaxial 2D – 1D Bragg cavity based Free-Electron Maser, utilising a highcurrent (1.5kA), magnetically confined, thin annular electron beam with circumference of ~220mm, wall thickness of ~2mm and mean radius of ~35mm. The electron beam was transported through a 2m long coaxial drift-tube with inner and outer radii of 30 mm and 40mm respectively. Results obtained via numerical modelling and experimental observation are presented and compared.
