Princeton Plasma Physics Laboratory (PPPL) physicists collaborating on the Wendelstein 7-X (W 7-X) stellarator fusion energy device in Greifswald, Germany, were on hand for the Feb. 3 celebration when German Chancellor Angela Merkel pushed a button to produce a hydrogen-fueled superhot gas called a plasma. The occasion officially recognized a device that is the largest and most advanced fusion experiment of its kind in the world.
Shannon Greco, a science education program leader at PPPL, has been named one of the YWCA Princeton’s “women of excellence” for her work with young women and disadvantaged youth, including her help in starting two all-girls robotics teams for the YWCA Princeton.
The U.S Department of Energy (DOE) has awarded a total of 80 million processor hours on the fastest supercomputer in the nation to an astrophysical project based at the DOE’s Princeton Plasma Physics Laboratory (PPPL). The grants will enable researchers led by Amitava Bhattacharjee, head of the Theory Department at PPPL, and physicist Will Fox to study the dynamics of magnetic fields in the high-energy density plasmas that lasers create. Such plasmas can closely approximate those that occur in some astrophysical objects.
From launching the most powerful spherical tokamak on Earth to discovering a mechanism that halts solar eruptions, scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory advanced the boundaries of clean energy and plasma science research in 2015. Here, in no particular order, are our picks for the Top-5 developments of the year:
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.
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.
