| Title | 134: Characterization of QH-mode and EHO properties with edge toroidal rotation | ||

Affiliation: | General Atomics |
| Research Area: | ELM Control & Pedestal Physics | Presentation time: | Not requested | Co-Author(s): | K.H. Burrell, M. Fenstermacher |
| Description: | Determine the properties of QH-mode plasmas and the EHOs as a function of the edge toroidal rotation. Change the edge toroidal rotation over multiple cycles of decreasing and increasing edge rotation in Q-mode plasmas and evaluate how the QH-mode plasmas and the EHO characteristics change. This is an ITPA related joint experiment. | ||
| Experimental Approach/Plan: | Establish QH-mode plasmas and then vary the edge rotation by changing the raio of co to counter beams in which the edge rotation decreases and increases over multiple cycles. Determine how the QH-mode plasma properties and the EHO characteristics change over these cycles through documentation by multiple edge diagnostics, especially theedge turbulence diagnostics. | ||
| Background: | Our knowledge of QH-mode plasmas and the EHO properties can be improved significantly by gaining a large set of data related to their dependence on the edge toroidal rotation, which appears to strongly affect the characteristics of the QH-plasmas and the EHOs.This experiment aims to obtain a systmetic and comprehensive data set on these quantities as a function of the edge toroidal rotation for a large range of operating conditions. | ||
