Charged Particle Optics Simulations and Optimizations for Miniature Mass and Energy Spectrometers
… the focusing properties of a variety of charged particle optics systems. The combined use of several software packages and custom computer code allows for modeling electrostatic and magnetostatic fields and the trajectory of particles through them. Several applications of this functionality are …

Third-order charged particle beam optics
The motion of a charged particle through a magnetic field configuration can be described in terms of deviation from a certain ideal trajectory. One uses power series expansion of the phase-space coordinates to obtain the transfer matrices for a particular optical system. In this thesis we present a …

Development of an ion transport system for singly charged ion injection into an electron string ion source (ESIS) charge-breeder
… through a beam-line system consisting of charged particle optics such as focusing einzel-lenses, an electrical quadrupole switchyard for 90◦ beam bending, and subsequent correction and focusing lenses before the entry port into the ESIS. A replica of the full system was created and used to study …

Conceptual problems in theory appraisal
… comparing the conceptual problems of wave and particle optics, and identifying the appraisal criteria that historical figures actually employed. I argue that the inferior status of the particle theory in dealing with conceptual problems was the primary cause of the optical revolution. Based on …
