The IMAGE Family

Discrete Coulomb interactions

The IMAGE family of software packages computes the combined effects of aberrations and discrete Coulomb interactions in electron and ion beams by direct ray-tracing. Various upgrades allow application to a large range of systems including combinations of round lenses, deflectors and stigmators, multipole systems, electron mirrors and Wien filters.

Simulation of aberrations and discrete Coulomb interactions for round lens systems.


IMAGE-LENS allows the analysis of systems containing round lenses only. Accurate direct ray tracing eliminates the need to use conventional aberration theory, and the method is therefore applicable to systems with aberrations of any order. The software computes and plots the total blur including both aberrations and coulomb interaction effects.   Post-processing facilities are included, for plotting point spread functions (with systematic or random initial conditions) and through-focal series of edge blur diagrams.

Upgrade to handle deflectors, multipole lenses and Wien filters.


The IMAGE software extends the capabilities of IMAGE-LENS to allow the analysis of a wide range of systems which, in addition to round lenses, can include combinations of multipole lenses, deflectors, stigmators and Wien filters.

Parallel execution on multi-core processors.


In PARALLEL-IMAGE we have introduced new algorithms that take advantage of the multi-core CPUs available in most modern PCs. The time-intensive parts of the programs involve the computation of the discrete Coulomb forces between particles in the system. This force computation has been significantly speeded up by using a hierarchical tree algorithm that operates in parallel, so that the Coulomb forces on each time-step of the ray-trace can be computed on all the available cores in the PC.

Upgrade for tolerancing capability.


Real columns suffer from asymmetry errors caused by small mechanical imperfections during construction and alignment.  Using the IMAGE-TOLERANCE software the user can compute the perturbation fields and aberrations due to tilts, misalignments and ellipticities in the electrodes or cathodes, to ensure that the system will perform in accordance with its design specifications. The IMAGE-TOLERANCE software allows the combination of aberrations and coulomb interactions to be computed and plotted for a system with asymmetry errors.

Simulation of electron and ion mirrors

The MIRROR-IMAGE package uses a direct ray trace to calculate the combined effects of aberrations and discrete coulomb interactions in systems containing an electron mirror.
