Fig 11. Multiple reflections of an oblique electron beam in a
mirror magnetic field. The cyclotron motion is the fastest
periodic motion, followed by the slower bounce motion between
the mirror points. Gradient and curvature drifts cause a third,
slowest rotation azimuthally around the mirror axis. This is
the classical charged particle motion in the ionosphere in
Earth's magnetic dipole field. Collisions and other scattering
processes diffuse the beam.
