71. Focal Properties of the Two-Tube Electrostatic Lens for Large and Near-Unity Voltage Ratios
Topic: Electron Physics
Published: 4/1/1974
Authors: D DiChio, S Natali, C Kuyatt
Abstract: Accurate calculations of focal properties of the two-tube electrostatic lens are extended to cover a range of voltage ratios from 1.1 to 10000. The accuracy of the calculations is discussed in detail. For voltage ratios near 6400 the lens is found t ...

72. Use of Matrices to Represent Electron Lenses. Matrices for the Two-Tube Electrostatic Lens
Topic: Electron Physics
Published: 4/1/1974
Authors: D DiChio, S Natali, C Kuyatt, A Galejs
Abstract: The use of matrices to represent electron lenses is discussed. It is shown that it is more convenient and natural to represent a lens by a matrix and that the matrix elements show a more regular behavior than do the focal properties. Thus matrices a ...

78. Electron Energy Loss Spectroscopy of Acetone Vapor
Topic: Electron Physics
Published: 11/15/1973
Authors: R Huebner, Robert Celotta, S Mielczarek, C Kuyatt
Abstract: High resolution, inelastic electron scattering data can provide new spectroscopic information on the electronic structure of polyatomic molecules. Features in the acetone energy loss spectrum from 0 to 15 eV obtained for 100 eV incident electrons cor ...

80. Representation of Focal Properties of the Equal-Diameter Two-Tube Electrostatic Lens for Computer Calculations
Topic: Electron Physics
Published: 11/1/1973
Authors: A Galejs, C Kuyatt
Abstract: Previous calculations have given accurate first-order focal properties for the two-tube electrostatic lens at discrete voltage ratios. For computer optimization, calculations involving systems of two-tube lenses, one must be able to calculate the fo ...
