The National Spherical Torus Experiment (NSTX), which underwent a $94 million upgrade, is being repaired. It will be the most powerful experimental fusion facility, or tokamak, of its type in the world when it is back in operation. Experiments will test the ability of the upgraded spherical facility to maintain a high-performance plasma under conditions of extreme heat and power. Results could strongly influence the design of future fusion reactors.

Jonathan E Menard

Jonathan Menard is responsible for guiding the research program of PPPL working with the laboratory's domestic and international research team. His research interests include the magnetohydrodynamic (MHD) equilibrium and stability properties of spherical torus (ST) and tokamak plasmas, advanced operating scenarios in the ST, and the development of next- step ST options for fusion energy. 

Masayuki Ono

Masa Ono is project director of the National Spherical Torus Experiment-Upgrade (NSTX-U). Ono has led
a number of PPPL research teams including those involved in the Advanced Concept Torus (ACT-1), 
the Current Drive Experiment (CDX), the Current Drive Experiment Upgrade (CDX-U) and the NSTX. He is a fellow of the American Physical Society and the author of more than 250 scientific papers. 

Dr. Richard J Hawryluk

Richard Hawryluk, Associate Director for Fusion, is an internationally-known physicist and a former deputy director of PPPL. He served as the head of the National Spherical Torus Experiment-Upgrade (NSTX-U) Recovery Planning Project from 2016 through August of 2017.  He served as interim director of the Laboratory from September 2017 through June 2018.
