Turbulence, the violently unruly disturbance of plasma, can prevent plasma from growing hot enough to fuel fusion reactions. Long a puzzling concern of researchers has been the impact on turbulence of atoms recycled from the walls of tokamaks that confine the plasma.
Throughout the universe, supersonic shock waves propel cosmic rays and supernova particles to velocities near the speed of light. The most high-energy of these astrophysical shocks occur too far outside the solar system to be studied in detail and have long puzzled astrophysicists.
Machine learning, which lets researchers determine if two processes are causally linked without revealing how, could help stabilize the plasma within doughnut-shaped fusion devices known as tokamaks.
Predhiman Kaw, an internationally-known plasma physicist who is considered the father of India’s nuclear fusion program, was remembered fondly by his colleagues at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) last week after they learned of Kaw’s June 19 death.
Two major issues confronting magnetic-confinement fusion energy are enabling the walls of devices that house fusion reactions to survive bombardment by energetic particles, and improving confinement of the plasma required for the reactions. At the U.S.
A nationwide team of researchers led by physicist C.S. Chang of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has won the use of 269.9 million supercomputer hours to complete an extreme-scale study of the complex edge region of fusion plasmas.
For fusion to generate substantial energy, the ultra-hot plasma that fuels fusion reactions must remain stable and kept from cooling.

Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have helped develop a new computer model of plasma stability in doughnut-shaped fusion machines known as tokamaks.
Everyone knows that the game of billiards involves balls careening off the sides of a pool table — but few people may know that the same principle applies to fusion reactions.
Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics have simulated a mysterious self-organized flow of the superhot plasma that fuels fusion reactions.
Magnetic reconnection, a universal process that triggers solar flares and northern lights and can disrupt cell phone service and fusion experiments, occurs much faster than theory says that it should. Now researchers at the U.S.
NASA aerospace engineer Aprille Ericsson told more than 600 seventh- to tenth-grade girls at the Princeton Plasma Physics Laboratory’s Young Women’s Conference that she was depending on them to pursue their dreams and make their ideas a reality in the wide-open field of Science, Technology, Engin
Like a potter shaping clay as it spins on a wheel, physicists use magnetic fields and powerful particle beams to control and shape the plasma as it twists and turns through a fusion device.
More than 35 students from Orange in the north and Moorestown in the south came to the U.S.
Two Princeton-area teams will travel to Washington, D.C., to compete in the National Science Bowl® finals after winning the regional middle school and high school competitions at the U.S.

Teams of middle school and high school students from as far away as Delaware and New York will come to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) Feb. 24 to Feb.
U.S. Department of Energy (DOE) high-performance computer sites have selected a dynamic fusion code, led by physicist C.S. Chang of the DOE’s Princeton Plasma Physics Laboratory (PPPL), for optimization on three powerful new supercomputers.
Cancer research should focus on the “fundamentals of the origins” of mutating and rapidly reproducing cancer cells that make the disease so difficult to treat. So said Princeton University physicist Robert Austin at the Jan. 28 Ronald E. Hatcher Science on Saturday lecture series at the U.S.
Valeria Riccardo, new head of engineering at the Princeton Plasma Physics Laboratory, is a United Kingdom transplant who comes to the position with more than 20 years of experience in project management, fusion design, and analysis on two fusion devices in the U.K. that are similar to the U.S.
Physicist Igor Kaganovich at the Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and collaborators have uncovered some of the physics that make possible the etching of silicon computer chips, which power cell phones, computers, and a huge range of electronic devices.
