ROTATION OF CYLINDRICAL PLASMAS IN THE GAMMA 10 TANDEM MIRROR

Plasma rotation of cylindrical plasmas has been investigated using the visible spectroscopy in the GAMMA10 tandem mirror. Significant observations are as follows: (1) Radial profiles of an electrostatic potential obtained from rotations of various ions are identical; (2) A radial profile of a diamagnetic flow velocity varies with ion species, which indicates that diamagnetic drift is different for different ion species. This is the first clear experiment observing a diamagnetic drift in high temperature plasmas. {copyright} {ital 1997} {ital The American Physical Society}
