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.

July 13, 2017

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.

July 10, 2017

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.

July 5, 2017

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.

June 22, 2017

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.

June 13, 2017

For fusion to generate substantial energy, the ultra-hot plasma that fuels fusion reactions must remain stable and kept from cooling.

May 19, 2017

Lithium compounds improve plasma performance in fusion devices just as well as pure lithium does, a team of physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has found.

May 18, 2017

Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have simulated the spontaneous transition of turbulence at the edge of a fusion plasma to the high-confinement mode (H-mode) that sustains fusion reactions.

May 10, 2017

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.

April 5, 2017

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.

March 31, 2017

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.

March 29, 2017

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.

March 13, 2017

More than 35 students from Orange in the north and Moorestown in the south came to the U.S.

February 20, 2017

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.

February 17, 2017

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.

February 3, 2017

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.

January 30, 2017

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.

January 27, 2017

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.

January 19, 2017

Meg Urry was the first tenured woman professor in the Physics Department at Yale University and was often the only woman in her physics classes, including her graduate class at MIT, but she still heard a fellow student complain that women were unfairly given advantages over their male colleagues.

January 6, 2017

Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have for the first time directly observed a phenomenon that had previously only been hypothesized to exist.
