elektronikehän

Elektronikehän is a Finnish term meaning "the electron ring." It designates a circular path or ring-shaped component associated with electrons in both physics and electrical engineering. In Finnish usage, elektronikehä is formed from elektron- (electron) and kehä (ring), with elektronikehän being the genitive form meaning "of the electron ring."

In particle physics and accelerator technology, an electron ring refers to a storage ring or circular accelerator where electrons circulate under magnetic confinement; such rings are used to produce synchrotron radiation, study high-energy interactions, or for collider experiments.

In electronics, the term can describe a circular circuit element such as a loop antenna or toroidal coil, used in RF engineering, inductors, or wireless power transfer.

Derived from elektron- (electron) and kehä (ring), the term is standard in Finnish technical literature and education. Elektronikehä, in its genitive form elektronikehän, appears in discussions of circular circuits and beam dynamics.
