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.

Downloads

There are two ways to try CPO. A free edition with no time limit, or a 15-day evaluation with every option unlocked. Both are 64-bit and install in minutes.

Free · No time limit

Free 64-bit edition

CPO2D + CPO3D · users guide · on-line help · nearly 200 benchmark and example data files

For teaching, academic research and trying the programs out - not for commercial work. Limited to 150 segments in CPO2D and 400 in CPO3D, and the following advanced options are not included:

Large segment counts Scattering User cathode Dielectric Field import

The sample files are all included, but the larger ones ask for more segments than the free edition allows and will stop with a message when you run them. The 15-day evaluation runs every one of them.

Doing paid work with CPO? That needs a purchased licence. See the licence for what the free edition covers.

Evaluation · 15 days · Every option

15-day evaluation

CPO2DS + CPO3DS · users guide · on-line help · nearly 200 benchmark and example data files

The full software, including space charge, cathodes and every advanced option - up to 5,000 segments in CPO2DS and 12,000 in CPO3DS, more than enough for any problem.

Fifteen days not enough? Ask us and we will extend it - we would rather you had time to decide properly.

Near those segment limits? You're probably not taking advantage of the Boundary Element Method - reworking the problem usually improves calculation times too.

We no longer offer 32-bit builds due to the memory limitations of 32-bit processes - the free 64-bit edition should be sufficient for testing older machines.
