Improved understanding of properties of the current filamentary structures in the edge plasma region is believed to allow better insight into development and possible control of the Edge localised modes (ELMs) and consequently, mitigation of their impact on the plasma performance and the first wall structures. We have focused on measurements of electric and magnetic properties of the filaments and electromagnetic features of the edge turbulence on TJ-II. We used a probe consisting of two 3D coil sets, two Hall sensors and 4 Langmuir tips. We present the first results of measurements with this probe on TJ-II stellarator.
