Design of electrooptical system with annular cathode and electrostatic compressor
Abstract
An electrooptical system employing an annual converging beam and an electrostatic compressor is examined in which the beam is compressed in the compressor field and gradually takes on a solid cylindrical form. The compressor is a system of two electrodes consisting of coaxial conical surfaces. The electrons are deflected and put into trajectories parallel to the axis by the transverse electrical field of a compressor, which is also the anode of the electrooptical system. Optimization by numerical analysis is performed by computer with allowance made for a relativistic increase in the mass and intrinsic magnetic fields of the beam. The optimum radius of curvature of the emitter surface is found to be significantly larger than that indicated in the preliminary calculations, and can be increased to infinity with no significant loss of laminarity of the trajectories.
