TJ-II is a four period, low magnetic shear stellarator (R = 1.5 m, a < 0.22 m, B0 ⩽ 1.2 T) which was designed to have a high degree of magnetic configuration flexibility. In the most recent experimental campaign, couplingof the full ECRH power (PECRH ⩽ 600 kW) to the plasma has been possible using two ECRH transmission lines which have different power densities. Both helium and hydrogen fuelled plasmas have been investigated. The article reviews the latest physics results in particle control, configuration effects, and transport and fluctuation studies.
