High-speed tangentially viewing soft x-ray camera to study magnetohydrodynamic fluctuations in toroidally confined plasmas (invited)

A high-speed tangentially viewing soft x-ray camera system has been developed and installed on the large helical device (LHD) using a video camera with a maximum framing rate of 13.5 kHz. Low-frequency activities, for example, structures with toroidal/poloidal mode number n/m=1/2, are directly detected with this system.
