Design Study of a Toroidal Electrostatic Analyzer.
Abstract
The design of a toroidl, electrostatic analyzer is discussed with special emphasis on the instrument providing channels of data by sampling different points of the energy spectra simultaneously. Two additional results of this study are that a toroidal analyzer can have four times the resolution of a spherical analyzer and can cover sixteen times as much of the energy spectra (with a fixed electrode voltage). The electrostatics, equations of motion, and the optic equations are discussed. The applications chapter discusses the use of multiple, off-center slits, the minization of the size of the instrument, the trade-offs that must be made in designing an instrument, the effect of field errors, the minimization of the effects of the field errors, and the total beam current as seen by the detector. Included in the appendix are design curves that should be of assistance to the reader in designing his own instrument. (Author)
