Abstract :
A theory is presented for the design of an ideal non- relativistic circular beam system including a charged- particle emitting diode, a diode aperture, a circular beam tunnel, and a focusing magnetic field that matches the beam from the emitter to the beam tunnel. The magnetic field is determined by balancing the forces throughout the gun and transport sections of the beam system. OMNITRAK particle trajectory simulations are performed, validating theory. The ideal circular electron beam system has wide applications in space-charge- dominated accelerator research, high energy density physics (HEDP) research, vacuum electronics, and medical and industrial accelerators.
