Anyon emitter

From Memory Alpha, the free Star Trek reference.

An anyon emitter is a device that uses anyon particles to neutralize the effects of an interphase generator and chroniton fields.

The USS Enterprise-D's anyon emitters in Ten Forward were used in 2368 to perform an anyon sweep in order to return Lt. Cmdr. Geordi La Forge and Ensign Ro Laren to their normal phase after being phase-cloaked by a Romulan interphase generator. (TNG: "The Next Phase")
