A study of Glaser's Ball – Shaped Magnetic Lens under the Effect of Current Density

Abstract

A computational investigation has been carried out on the design and properties of Glaser's lens. The limiting factor in magnetic lens design is the current density that can be supported by the coil. The current density was used as parameters of the magnetic lens design. These parameters were studied for finding the minimum spherical and chromatic aberration coefficients. The computed aberration has been normalized in term of focal length under zero magnification condition.
