Trak (Vers. 6.0) is one of the most advanced codes available on any computer platform for charged-particle optics and gun design. The program applies high-accuracy finite-element techniques to calculate single-particle orbits or to simulate steady-state beams in 2D (planar or cylindrical) electric and magnetic fields. Features include effects of beam-generated electric and magnetic fields, automatic generation of input distributions, self-consistent space-charge-limited emission, and field emission. Applications include electron and ion guns, electro-optical devices, electron microscopes, vacuum microelectronics and relativistic high-power beams. (Available for Linux and Windows.
Requires Mesh 5.0, EStat 5.0 and BStat 5.0.)
- Easy-to-understand instruction manual with a library of read-to-run examples.
- Combine effects of calculated electric and magnetic fields on independent meshes.
- Self-consistent space- charge-limited emission from multiple sources.
- High accuracy orbit calculations, even near electrode surfaces
- Precision interpolation to stopping planes for lens characterization.
- Interactive orbit and field plotting postprocessor with built-in hardcopy support.
- Automatic calculation of self-consistent plasma surfaces for ion extraction.
- Advanced secondary- emission models and automatic tracking of multi-generational electron histories.
- Automatic calculations of emittance and current density.
- Formatted text output files make it easy to transfer information to user applications or to mathematical analysis programs.
