Staff Research Physicist-RF Plasma Heating Experimentalist
PPPL/NSTX-U has an opening for a physicist at the research staff position level to conduct radio frequency (RF) plasma heating experiments, including diagnosis and analysis of RF performance, and to develop and operate high-power RF systems. The main focus of the position is to support High Harmonic Fast Wave (HHFW) research on NSTX-U, for which the goal is to efficiently heat the plasma with up to 6 MW of RF power. Considerable emphasis will be placed on understanding RF power Joss to the plasma edge region to maximize the core plasma heating efficiency and minimize erosion/impurity production from the divertor and other plasma facing components. Additional support will also be provided for RF heating and power deposition studies in the electron cyclotron (EC) and helicon ranges of frequencies on the DIII-D tokamak at General Atomics in San Diego, CA, in the ion cyclotron range of frequencies (ICRF) on the Cmod tokamak at MIT in Cambridge, MA, and in the IC and EC ranges of frequencies on the EAST tokamak at ASIPP in Hefei, China. Longer term, NSTX-U may also pursue ECRF heating in support of plasma start-up. The research and development will be carried out primarily at PPPL, but will also involve off-site travel in support of the aforementioned collaborations.
Education should be at the PhD level, and 3 years or more experience (after PhD) in RF research in tokamaks is strongly preferred.
