Paper Abstract

A 7-18 GHz reflectometer system is installed to the central cell of the GAMMA 10 tandem mirror. The system is at first used to provide radial information of the density fluctuations. Two types of instabilities, low-m ExB-driven rotational modes and drift waves are identified by using the reflectometer as well as the Fraunhofer-diffraction system. The fluctuation level of both instabilities is observed to depend on the radial electric field, and is stabilized by applying a bias voltage to the end plates to suppress the ambipolar radial transport of a tandem mirror plasma.
