TL;DR: In this paper, the authors describe the requirements for high reliability in the systems (diagnostics) that provide the measurements in the ITER environment, which is similar to those made on the present-day large tokamaks while the specification of the measurements will be more stringent.

Geodesic–acoustic-mode in JFT-2M tokamak plasmas
Takeshi Ido,Y. Miura,Kensaku Kamiya,Y. Hamada,Katsumichi Hoshino,Akihide Fujisawa,Kimitaka Itoh,S.-I. Itoh,A. Nishizawa,H. Ogawa,Yoshinori Kusama +10 more
TL;DR: In this paper, the characteristics of geodesic-acoustic-mode (GAM) were investigated through direct and simultaneous measurement of electrostatic and density fluctuations with a heavy ion beam probe.
Journal ArticleDOI
Observation of the interaction between the geodesic acoustic mode and ambient fluctuation in the JFT-2M tokamak
