Charged-particle ray trace Decorative artwork in the style of a CPO simulation plot: charged-particle trajectories, drawn as fine lines, converge through a crossover at a focal point marked by a glowing dot — the kind of ray trace the CPO programs produce.

CPO2D

Simulation of 2-dimensional electrostatic systems with the Boundary Element Method — fully relativistic, in r and z for rotationally symmetric systems or x and z for planar ones. Included with every 3D edition.

About CPO2D

The only commercial program which uses the very accurate and fast Boundary Element Method — described as the gold standard of electrostatic simulation programs.

A program for the simulation of 2-dimensional electrostatic systems. The 2 dimensions are either r and z for rotationally symmetric systems, or x and z for planar systems.

The program is fully relativistic and includes a vast range of options and capabilities, such as automatic focusing, easy-to-calculate lens properties, secondary rays, time-varying voltages, electrode shapes from a library or defined by user’s equations.

A very large range of template data files illustrate the accuracy and speed, backed by an exceptionally comprehensive on-line Help system.

Not sold separately

Included with every 3D edition

CPO3D, CPO3DS and CPO Complete all install CPO2D alongside the 3D programs — buy any 3D edition and the 2D edition is part of the package.

Just exploring? The free 64-bit edition of CPO2D installs without a licence key.

Capabilities

What CPO2D gives you

Automatic focus optimisation Iterates voltages for you until the focus lands where you want it. Lens properties & coefficients Cardinal points, aberration and spectrometer coefficients, calculated directly. Secondary rays Flexible ray definition, including secondaries generated at surfaces. Time-varying voltages Time-dependent potentials on any electrode (pulsed beams: CPO2DS). Electrode shape library Electrodes scaled, moved, rotated, stretched, cropped, copied and repeated. User-defined equations Shapes and behaviours defined by your own equations where the library ends. Template data files A very large set of worked examples demonstrating accuracy and speed. Benchmarked accuracy Published benchmark tests against known analytic results.
