Electrostatic energy analyzer using a nonuniform axial magnetic field
Abstract
Electrostatic electron-energy analysis in a strong magnetic field using conventional retarding-field methods may be inaccurate because these devices discriminate against parallel momentum, and not total energy. It is shown how a magnetic-field minimum at the point of minimum potential can remove this difficulty. Examples of elastic and inelastic electron-atom scattering, and of electron energy loss in a plasma, are given.
