| Title | 39: Measure and understand energetic particle profiles in steady-state plasmas | ||
| Name: | William Heidbrink heidbrink@fusion.gat.com | Affiliation: | University of California, Irvine |
| Research Area: | Steady State Heating and Current Drive | Presentation time: | Not requested |
| Co-Author(s): | John Ferron, the Energetic Particle group | ITPA Joint Experiment : | No |
| Description: | Acquire FIDA profiles & measure coherent instabilities in a set of steady-state plasmas with different values of qmin | ITER IO Urgent Research Task : | No |
| Experimental Approach/Plan: | Reproduce the 2009 betan=2.7 qmin scan. Modify the beam programming to acquire FIDA profiles from all three systems. Optimize fluctuation diagnostics for Alfven eigenmode measurements. Also reproduce the q95 scan. | ||
| Background: | The FIDA active beam diagnostics require beam modulation patterns that are rarely achieved during usual steady-state operation. By operating at betan=2.7, we can achieve a condition that is relevant to the highest performance plasmas while maintaining sufficient flexibility to obtain good data. | ||
| Resource Requirements: | All beams except 210LT. | ||
| Diagnostic Requirements: | FIDA, ECE & ECEI, BES, UCSD camera + .... | ||
| Analysis Requirements: | NUBEAM & FIDASIM calculations for all good shots. Alfven eigenmode stability calculations. | ||
| Other Requirements: | |||
