Fusor

The fusor is a nuclear fusion device which uses electrostatic fields confine the ions. It is also referred to as an inertial electrostatic confinement device (IEC).

In general, a fusor consists of two concentric electrodes between which a potential difference is applied. Ions and electrons that are introduced or created between the electrodes are accelerated by the electric field. For fusion purposes, the inner electrode is the cathode, i.e. it is at negative potential, and the cathode is made mostly transparent. Therefore, the ions are accelerated radially inwards and will pass through the cathode most of the time. The ions will exhibit an oscillary motion in radial direction.
