Aberrations of an electrostatic three-cylinder system used to simultaneously focus and deflect charged particles

Aberrations of an electrostatic three-cylinder system used to simultaneously focus and deflect charged particles

The properties have been studied of an electrostatic three-cylinder lens-deflector in which the middle cylinder is split longitudinally into four parts, allowing the system to be used to simultaneously focus and deflect a beam of charged particles. The aberrations are found to be of first order in t...

Description
Summary:The properties have been studied of an electrostatic three-cylinder lens-deflector in which the middle cylinder is split longitudinally into four parts, allowing the system to be used to simultaneously focus and deflect a beam of charged particles. The aberrations are found to be of first order in the deflection.
