Abstract

A 200 keV heavy ion beam probe system has been prepared to measure potential profiles in the compact helical system. Probing beam trajectory is successfully controlled by a secondary beam sweep system to keep the injection angle of the secondary beam constant during the radial scan. As a result, it was observed that the potential profile changes after the neutral beam heating is applied on electron cyclotron heated plasmas.
