Active control of ELMs and small-ELM/ELM-less regimes
Short CVMax Fenstermacher has been a physicist in the Magnetic Fusion Energy Program at Lawrence Livermore National Laboratory (LLNL) since 1988.
He was a double major in mathematics and physics as an undergraduate, and completed both his MS (1980 – ELMO Bumpy Torus) and PhD (1983 – Stochastic Differential Equations in the Kinetics of Magnetized Plasmas) in Nuclear Engineering (Plasma Physics) at the University of Michigan. He began his professional career in 1983 on location at LLNL as a member of the TRW plasma physics group supporting the MFTF-B tandem mirror.
In 1988 he joined the LLNL staff supporting the Microwave Tokamak Experiment (MTX) to couple the ALCATOR-C tokamak to a Free Electron Laser (FEL).
Since 1994, he has been a member of the LLNL experimental team located at the DIII-D National Fusion Facility in San Diego.
Other research interests have included fusion reactor optimization studies for both tandem mirrors and tokamaks, lower hybrid current drive simulations, divertor detachment physics and 2D fluid modeling, high temporal resolution Edge Localized Mode (ELM) characterization, and Quiescent H-mode (QH-mode) research.
His primary research focus since 2005 has been the control of ELMs in tokamaks including ITER, using 3D magnetic perturbation fields. He currently serves as a US representative to the ITER Science and Technical Advisory Committee (STAC), has been the chair of the International Tokamak Physics Activity (ITPA) ELM Control working group since 2008, and has served for 8 of the last 10 years as the Experimental Coordinator for the DIII-D tokamak research program.
