Anyons are subatomic particles that can be used to eliminate chroniton fields.
In 2368, Lieutenant Commander Data used an anyon emitter to eliminate anomalous chroniton fields which were appearing at seemingly random locations aboard the USS Enterprise-D, after they had assisted a Romulan science ship which had suffered an accident while attempting to utilize an experimental interphase generator. It was eventually discovered that, as a result of Lieutenant Commander Geordi La Forge and Ensign Ro Laren being "phased" by the generator, they were leaving chroniton fields in their wake every time they passed through a solid object. Using high-intensity anyon emissions, Data was able to de-phase La Forge and Ro. Anyon emissions were considered harmless to organic life, as such, the anyon emissions were safe to emit within populated areas. (TNG: "The Next Phase")
