Trak 7.0 is the most advanced 2D code 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 industrial guns, electro-optical devices, manufacturer of electron microscopes, vacuum microelectronics and relativistic high-power beams. (Requires Mesh 6.0, EStat 6.0 and PerMag 6.0.)
