Surface switching of rotating fluid in a cylinder
We study the surface shape of water in an open cylinder driven by constant rotation of the bottom. Around the critical Reynolds number for the laminar-turbulent transition, the surface deformation,Expand

Design and construction of the LHD plasma vacuum vessel
In the reactor design, many components are installed in a narrow space between the superconducting coil and the plasma. In the large helical device (LHD) configuration, the plasma axis is shiftedExpand

3D real-time monitoring system for LHD plasma heating experiment
Abstract The java -based real-time monitoring system has been in use at the National Institute for Fusion Science, Japan, since the end of March 1988 to maintain stable operations. This systemExpand

Completion and trial operation of the superconducting magnets for the Large Helical Device
The Large Helical Device (LHD) is a plasma physics experimental device having two superconducting helical coils and three pairs of poloidal coils. All assembly and attachment works of LHD wereExpand

Which to choose for volumetry : MPRAGE or SPACE ?
Introduction: From a clinical viewpoint, T1-weighted images is used to evaluate lesion signal at pre& post-contrast enhancement. Especially in contrast-enhanced cases, T1-weighted 3D variable flipExpand

Rotating flow transition related to surface switching
We have investigated quantitatively the recently reported phenomena called "surface switching" that occurs in the flow driven by a rotating disk in an open cylindrical vessel [1]. The deformed freeExpand

High resolution distortion-free diffusion-tensor imaging of craniovertebral junction
Diffusion-weighted imaging (DWI) using single-shot echo-planar imaging (SS-EPI) has been used widely for clinical applications, especially in the acute brain ischemia. However this method suffersExpand
Experimental studies towards long pulse steady state operation in LHD
In the Large Helical Device, stable discharges lasting longer than one minute have been obtained using the complete heating scheme, including ECH. The plasma is sustained with NBI or ICRF of 0.5-1Expand
