Abstract Text:
An X-Ray Imaging Crystal Spectrometer (XICS) diagnostic has been installed on LHD which can provide high resolution profiles of the ion-temperature, electron-temperature, poloidal flow velocity and argon density. This installation proves the applicability of this diagnostic technique to current and future 3D magnetic fusion devices. XICS is now a mature diagnostic with installations on both tokamak and stellarator fusion experiments. The diagnostic implementation and analysis techniques are described, including tomographic techniques to recover true profiles from line the integrated profile measurements. Application of these measurements to current fusion science topics is discussed, including the study of heat and impurity transport as well as intrinsic or driven plasma flows. Finally we discuss future plans for the installation of this diagnostic on future plasma devices.
