Focusing of Neutral Particle Beams by Fictitious Force Fields

摘要

In a rotating coordinate system the Coriolis force and centrifugal force can account for the curved trajectories followed by moving particles. It is shown that particle trajectories diverging from a source fixed in the rotating system may come to a focus at another point fixed in the system. Both first‐ and second‐order focusing are obtained and an example of each is given. Expressions are derived for velocity dispersion and for the transverse aberration at the focus.
