Abstract :
Structure of magnetohydrodynamic instabilities are observed by a tangentially viewing soft X-ray camera system in the large helical device. Displacement at the rational surface is estimated to be an even function at the mode rational surface by comparison with synthetic image assuming the displacement of the mode.
