Physicist Fatima Ebrahimi at the U.
S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations present that the technique,known as coaxial helicity injection (CHI), could also benefit tokamaks that use superconducting magnets. The research was published in March 2016, or in Nuclear Fusion,and was supported by the DOE's Office of Science.
