Research Abstract

The novel analyzer which can measure the space simultaneous multipoint has been developed and established to clarify the mechanism of growth and decay process of plasma instability related to the plasma confinement using a heavy ion beam probe which can measure the potential and density in the high temperature plasma. We evaluated the performance of established novel analyzer and confirmed the totally satisfying performance required for the development subject. It was successful to measure the space simultaneous multipoint of potential and density, and local electric field with absolute accuracy.
