# Ion Beam Simulator

Ion Beam Simulator or IBSimu is an ion optical computer simulation package for ion optics, plasma extraction and space charge dominated ion beam transport using Vlasov iteration. The code has several capabilities for solving electric fields in a defined geometry and tracking particles in electric and magnetic fields. The code is a constructed as a C++ library for maximal versatility and openness.

IBSimu is usable in Linux and Windows.

IBSimu is released under GNU General Public Licence.

### Highlighted features

- Solid geometry definition using 2D DXF files, 3D STL files, mathematical formulation, etc.
- Finite Difference Method solver for 1D, 2D and 3D Poisson equations with edge smoothing.
- Particle trajectory iteration in self-consistently calculated electric and imported magnetic fields.
