However, if you *Accelerate* a *charged* particle (by forcing it to travel in a circle, for example), you will produce *photons* (synchrotron radiation, in this case). - Jim Van Zandt

For nonrelativistic particles, the radiation from an accelerated charged particle is mostly normal to the path of the particle. For relativistic particles, the radiation is forward (like headlights on a car). (See Jackson, _Classical Electrodynamics_, 2nd edition, page 663, figure 14.4) - Jim Van Zandt

From: Rick McGeer (on an aaa-60-s) <mcgeer%ucbkim@Berkeley> Hmm. In either case, with appropriate mirrors, we have a "Dean Machine", albeit not a very powerful one. Rick.
