Significantly improved spatial uniformity of bremsstrahlung radiation, relative to a diode with a planar anode, is predicted for the HERMES III accelerator when a compound-lens diode is used to actively control the high-power electron beam at the exit of a coaxial, magnetically-insulated transmission line. Electron flow within the diode and subsequent radiation output is characterized as a function of diode parameters. The results of these calculations are applicable to coaxial geometries where active control of high-energy, high-current, /spl nu///spl gamma/ /spl ges/ 1 beams is desired. |
