On the status of the investigation of the INCA discharge — •Christian Lütke Stetzkamp, Tsanko Vaskov Tsankov, and Uwe Czarnetzki — Institute for Plasma and Atomic Physics, Ruhr University Bochum, D-44780 Bochum, Germany

Recently a novel concept for collisionless electron heating and plasma generation at low pressures was theoretically proposed [1]. It is based on periodically structured vortex fields, which produce certain electron resonances in velocity space. The concept was experimentally realized by the inductively coupled array (INCA) discharge and first experimental results in atomic gas plasmas were presented in [2].

Here, an overview of the recent advances in the analysis of the discharge are given. Experimental results regarding the discharge operation in molecular gases as well as investigation of an alternative electric field configuration proposed in [1] are presented. The future challenges and possibilities of the concept are discussed.
