One of the principal challenges remaining for realizing magnetic fusion energy is to understand and mitigate the chaotic flows of ionized gas, or plasma, that lead to unacceptable energy loss from the hot core of the device. These microscopic, randomly varying, or turbulent, fluctuations of plasma velocity and temperature arise owing to the strong differential in temperature from the hot core (>100,000,000 degrees) to the surrounding wall...
Princeton astrophysicist Lyman Spitzer Jr. (1914-1997) was among the 20th Century’s most visionary scientists. His major influences range from founding the Princeton Plasma Physics Laboratory (PPPL) and its quest for fusion energy, to inspiring the development of the Hubble Space Telescope and its images of the far corners of the universe.
More than 350 participants from around the world will gather in Plainsboro, N.J., on September 30 for the 66th Annual Gaseous Electronics Conference (GEC). The week-long event will bring together physicists from numerous plasma science disciplines for workshops, panels and poster sessions on topics ranging from basic research to uses for plasma in microchip etching, nano- material manufacturing and other technologies.

The U.S. Department of Energy’s Princeton Plasma Physics Laboratory has released “Star Power,” a new informational video that uses dramatic and beautiful images and thought-provoking interviews to highlight the importance of the Laboratory’s research into magnetic fusion.
The 10-minute movie will be shown to the thousands of visitors who come to PPPL on tours and is posted on the Laboratory’s website, www.pppl.gov.
Researchers at the Princeton Plasma Physics Laboratory (PPPL) and the U.S. Department of Agriculture (USDA) have developed a novel technique and device for rapidly pasteurizing eggs in the shell without damaging the delicate egg white. The process could lead to a sharp reduction in illnesses caused by egg-borne salmonella bacteria, a widespread public health concern.
Summer is a time that many teenagers prefer to spend relaxing and soaking up the sun at the beach, but 10 high school students at PPPL decided instead to spend their summer soaking up plasma physics knowledge and performing hands-on research.
The high school interns started on July 1, taking a three-day introductory course in plasma physics, offered as part of the program for the first time. Following the course, the students scattered throughout the Laboratory with each assigned a mentor.
Dutch graduate student Jasper van Rens recently completed a three-month assignment at PPPL to study a diagnostic technique that will be crucial to the success of ITER, the huge international fusion facility under construction in France. Working with Fred Levinton and Howard Yuh of PPPL subcontractor Nova Photonics, Van Rens investigated the impact of reflected light on the ITER Motional Stark Effect (MSE) instrument, which measures the internal magnetic configuration of fusion plasmas.
Leading experts from around the world gathered at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) in July to focus on a key issue for the development of fusion energy: Improving ways to predict and mitigate disruptions that can destroy magnetically confined plasmas that are needed for fusion reactions.
