Latest physics results of TJ-II flexible heliac

This paper is devoted to the presentation of the most relevant recent Physics results obtained in the TJ-II flexible heliac.Firstly ECRH modulation and plasma breakdown studies are summarised; then particle control techniques used to obtain reproducible discharges with density under control are presented.Transport studies show internal heat transport barriers that reduce heat conductivity to neoclassical values,and ELM-like transport events,similar to those observed in tokamaks and in other stellarators before and during H mode transition.Evidence of ExB sheared has been observed both in the proximity of rational surfaces.Finally,a high resolution Thomsom Scattering system has shown Te and ne profile structures
