**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

**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

**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
