Paper Abstract

The latest version of the particle optics computer aided design code POCAD is presented. This interactive code calculates properties of single pass charged-particle optical systems. The properties of CPO systems are calculated by TRAcking particles through the system and FItting transfer Coefficients to their end coordinates (TRAFIC). This approach allows for a general definition of the optical components in the system, which can be defined by analytical functions, transfer matrices, or full numerical calculations. After giving a general overview of the code, the paper focuses on techniques recently developed for specific applications. These include the direct tracing of particles through electrostatic and magnetic lenses using the axial potential generated by finite element method programs, and also the calculation of Coulomb interactions.
