| Title | 231: Hydrogen Confinement at Low Rotation | ||
| Name: | Steve Allen ( |
Affiliation: | Lawrence Livermore National Laboratory |
| Research Area: | Hydrogen Discharges | Presentation time: | Not requested | Co-Author(s): | -- |
| Description: | L-H transition physics in hydrogen. Assess affect of plasma rotation. Determine if the threshold can be reduced by plasma shaping, x-point height, direction of the grad-B drift, pumping. | ||
| Experimental Approach/Plan: | Operate DIII-D with close to the ITER shape and determine the L-H mode transition power and confinement properties. Vary the plasma rotation with the co-counter beam mix. | ||
| Background: | Initial ITER operation will be in hydrogen with limited power. | ||
| Resource Requirements: | Hydrogen operation with hydrogen beams - at least 2 beamlines, co and counter. | ||
| Diagnostic Requirements: | -- | ||
| Analysis Requirements: | -- | ||
| Other Requirements: | -- | ||
