Overview The Princeton Plasma Physics Laboratory (PPPL) seeks to fill an Associate Research Physicist position based at DIII-D General Atomics in San Diego, CA. This position will work on diagnostics and physics behind particle and thermal transport in the H-mode pedestal.   The research will largely center around major upgrades to the main ion charge exchange recombination spectroscopy system. This will include hardware upgrades to the spectrometer systems to meet an evolving set of measurement needs, including spectrally resolved passive D-alpha measurements for plasma fueling studies. Additionally, several advanced analysis techniques such as machine learning will be deplo
