Charged Particle Trajectories

LORENTZ computes the path of charged particles through electric and/or magnetic fields. It can solve or import the time and space dependence of E&B fields, then solve the dynamics of the particle motion under the LORENTZ force (F = qE + vxB) or due to mobility (v = µE) in a surrounding medium. Other factors that can be used as appropriate include: viscosity and wind speed of the medium, secondary emission from surfaces, and collisions with residual gas.

Some examples:

  • Ion mobility spectroscopy
  • Ion traps
  • Ion mass spectrometers
  • Time of flight
  • Deflector plates
