| Title | 354: The effect of plasma rotation on core-localized Alfven eigenmodes. | ||
| Name: | Gerrit J. Kramer ( |
Affiliation: | Princeton Plasma Physics Laboratory |
| Research Area: | Rotation Physics | Presentation time: | Not requested | Co-Author(s): | G.J. Kramer, R. Nazikian, W. Solomon, N.N. Gorelenkov |
| Description: | Plasma rotation modifies the the measured spectrum of Alfven Eigenmodes
by Doppler shifting the modes with the toroidal mode number times the toroidal plasma rotation frequency at the mode location. The Alfven continua are also also Doppler-shifted. This can influence the continuum damping of the Alfven eigenmodes. | ||
| Experimental Approach/Plan: | We propose to study the influence of the plasma rotation on the
stability of the the Alfven eigenmodes by varying the plasma rotation from co- to counter-rotation with the new set of beams in otherwise identical discharges. The fast-ion population that destabilized the TAEs can be created by ICRH. | ||
| Background: | -- | ||
| Resource Requirements: | DIIID's rotated beam line makes these experiments possible and the
set of fluctuation and plasma rotation diagnostics that can probe the plasma core are paramount for the success of such an experiment. | ||
