PPPL engineers complete the design of Wendelstein 7-X scraper unit

Engineers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have finished designing a novel component for the Wendelstein 7-X (W7-X) stellarator, which recently opened at the Max Planck Institute of Plasma Physics (IPP) in Griefswald, Germany. Known as a "test divertor unit (TDU) scraper element," the component intercepts some of the heat flowing towards the divertor — a part of the machine that collects heat and particles as they escape from the plasma before they hit the stellarator wall or degrade the plasma's performance.

PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid

Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have produced self-consistent computer simulations that capture the evolution of an electric current inside fusion plasma without using a central electromagnet, or solenoid. The simulations of the process, known as non-inductive current ramp-up, were performed using TRANSP, the gold-standard code developed at PPPL. The results were published in October 2015 in Nuclear Fusion. The research was supported by the DOE Office of Science.

Synthetic muscle experiment will likely return to Earth in March

A synthetic muscle experiment on board the International Space Station (ISS) that was developed with the help of PPPL scientists is now tentatively scheduled to return to earth in March of 2016 on a new SpaceX-10 rocket. It would be returning eight months later than originally planned after an unmanned SpaceX Falcon 9 rocket headed for the ISS exploded a few minutes after liftoff in late June.

PPPL honors engineer Charles Neumeyer and physicist Rajesh Maingi

PPPL presented its 2015 outstanding research awards to engineer Charles Neumeyer and physicist Rajesh Maingi following Stewart Prager’s October 5 State of the Laboratory address. Neumeyer received the Kaul Foundation Prize “For the design analysis and overall management of the U.S. contributions to the steady state electric network (SSEN) that will supply power to ITER.
