ELECTROSTATIC FOCUSING OF HOLLOW SPIRALING ELECTRON BEAMS.
Abstract
The conditions for a stable orbit under electrostatic focusing were derived for a coaxial geometry with tangential injection. Small deviations in injection velocity and direction are then considered and the trajectories are found to be stable against small perturbations. A simplified model of a spiral injection scheme is analyzed and found to offer the possibility of proper injection. Computer programs have been prepared to calculate trajectories for a wider range of input parameters and to calculate the potential in the spiral geometry injection scheme. A design for an experimental spiral gun has been prepared. (Author)
