ELECTROSTATIC FOCUSING OF HOLLOW SPIRALING ELECTRON BEAMS.

Abstract

Two experiments were performed during this quarter. The first experiment failed before significant operation was achieved. The cause of the failure was a broken filament. Enough experience was gained with this model to indicate the desirability of a change in design. The second, redesigned experimental model was operated and performance data were taken. The best transmission was about 20%. MAD programs were written for the solution of Laplace's Equation in cylindrical coordinates and for the calculation of electron trajectories in electrostatic fields neglecting space charge. Various injection conditions were calculated. (Author)
