DOE awards $134M for fusion research and development
The Department of Energy announced on Wednesday that it has awarded $134 million in funding for two programs designed to secure U.S. leadership in emerging fusion technologies and innovation. The funding was awarded through the DOE’s Fusion Energy Sciences (FES) program in the Office of Science and will support the next round of Fusion Innovation Research Engine (FIRE) collaboratives and the Innovation Network for Fusion Energy (INFUSE) awards.

At the L-2M stellarator, in the electron cyclotron resonance heating regime, the processes of plasma self-organization were studied in different successive phases of plasma confinement during the facility shot. It is shown that in the phase of initial plasma heating, because of the absence of plasma-wall interaction, the canonical pressure profiles of the electronic component are not formed. In the quasi-stationary phase, the forming pressure profiles are close to the canonical one, and the energy loss is somewhat higher than in the phase beginning immediately after switching off the microwave heating pulse. After turning off the microwave pulse, the self-organization processes form the canonical pressure profiles of the electronic component in plasma, which ensure minimal energy loss from the plasma. In this case, the total power of energy losses from the plasma is proportional to the cube of the plasma energy.
