Column Design including Wien Filters.
The WIEN family of software packages handles complete columns of round lenses, multipole lenses and Wien filters.
Multipole and Wien filter systems.
The WIEN program handles complete columns containing round lenses, multipole lenses and Wien filters and calculates aberrations up to 3rd-order.

Optimization of aberrations up to 3rd – order.
The WIEN-REFINE module takes the initial design of the column, and interactively refines it to optimise the performance. A electron beam column contains many design parameters that can be varied and there are numerous aberrations which each depend on the variable parameters. WIEN-REFINE allows the user to choose which design parameter to vary and which aberration to target. The program then runs several optimisation cycles and generally yields designs with better properties than those obtained through trial and error.

Optimization of aberrations up to 5th – order.
The WIEN-REFINE-5 module extends the functionality of WIEN-REFINE to allow optimisation of the aberrations up to 5th – order terms.
