  • Description of ion optical systems using matrices up to third order
  • Dipoles with inhomogenieties, quadrupoles and all kinds of multipoles both magnetic and electrostatic
  • Precise treatment of the fringing fields using fringing field integrals
  • Use of variables, fitting, plots of the system, trajectories, envelopes, fields and of phasespace distributions considering apertures, space charge of a KV-beam
