| Popis: |
Experiments using an electrically biased limiter have been performed on the Texas Experimental Tokamak (TEXT). A small movable limiter is inserted past the main poloidal ring limiter (which is electrically connected to the vacuum vessel) and biased at VLim with respect to it. The floating potential, plasma potential and shear layer position can be controlled. With ¦V Lim ¦⩾ 50 V the plasma density increases. For VLim 0 the results obtained are inconclusive. Variation of VLim changes the electrostatic turbulence which may explain the observed total flux changes. |
