Magnetostatic fields can be added. The electrostatic system can be easily synthesised from a comprehensive menu of electrode shapes. A space-charge option is available, which allows the use of cathodes of almost any shape.
Interactive graphics give easy viewing of electrodes, trajectories, contours and fields.
An iterative option is available for focussing and space-charge problems. One of the benchmark tests is for a space-charge limited spherical cathode. Literature reference None. Newest information on the CPO home page at the University of Manchester. Submitted by M.v.d.
