In particle accelerator environment, most of the power converters feeding magnet-loads have either thryristorized or diode bridge at their input stage. Loads to these power converters are fixed but they are operated through a wide current range. Such converters being non-linear loads to the mains produce considerable distortion in the supply current. Hereby, results in a poor total harmonic distortion...
A pulsed diode electron gun delivering 500mA current at 40kV is described. The gun geometry is optimized using the Electron Trajectory Program EGUN at higher scaling factors by choosing the closest converging starting surface. The effect of an annular gap between cathode and focusing electrode on beam behaviour is compensated by using a suitable focusing electrode. The estimated perveance is 0.065μperv...
