NSTX upgrade underway at PPPL.

Despite the general reductions forecast in the President's FY 2013 budget request to Congress, the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) is getting to start on a $94 million, project to upgrade the National Spherical Torus Experiment (NSTX), though at a slower pace than previously envisaged. The completion date, originally planned for 2014, is now planned for September 2015. The upgrade will enhance the capabilities of NSTX by upgrading the magnet system to permit higher plasma currents and magnetic fields and by installing a second neutral beam heating system to enable better control of plasma instability.

The upgrade "will provide a huge boost to all NSTX science missions and enhance U.S. fusion research capability," said Stewart Prager, director of PPPL. Experiments done on NSTX, he said, "will establish the physics basis to determine next steps in fusion research and development." PPPL physicists will use the upgraded NSTX facility to assess the role of more compact tokamak configurations.
