The ''ISTTOK Tokamak'' ("Instituto Superior Técnico TOKamak") is a research
fusion reactor (
tokamak) of the
Instituto Superior Técnico. It has a circular cross-section due to a poloidal graphite limiter and an iron core transformer. Its particularity is that it is one of the few tokamaks operating in AC (alternating plasma current) regime, as well in DC regime. In 2013, the AC operation allowed the standard discharges to extend from 35 ms to more than 1s.

Ball-pen probe
A ball-pen probe is a modified Langmuir probe used to measure the plasma potential in magnetized plasmas. The ball-pen probe balances the electron and ion saturation currents, so that its floating potential is equal to the plasma potential. Be ...
