In this paper we present the first quantitative measurement of the change in frequency (tune) with intensity of four transverse resonances in a high intensity Gaussian beam. Due to the nonlinear space charge forces present in high intensity beams, pa

Radio-frequency cavities used in modern particle accelerators operate in TM_{m10}-like modes composed of a single, dominant multipole of order m; m=0 modes are used for the longitudinal acceleration of a particle beam and m≠0 modes for controlling

Work has been underway for some time to design a compact electron beamline utilising X-band linear accelerating structures in the new Melbourne X-band Laboratory for Accelerators and Beams (X-LAB). The original design utilised an S-band RF photogun a
