1 day ago · Upon completion of construction of the main reactor and first plasma, planned for late 2025, [4] it will be the world's largest magnetic confinement plasma physics experiment and the largest experimental tokamak nuclear fusion reactor. It is being built next to the Cadarache facility in southern France.
2 days ago · A tokamak ( / ˈtoʊkəmæk /; Russian: токамáк) is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially-symmetrical torus. [1] . The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.

5 days ago · To produce these waves in plasma, scientists must have a greater understanding of light — specifically, the same sort of radio-frequency wave used in microwave ovens — which physicists already use to heat plasma. With greater understanding comes the greater possibility of control. “We are trying to find similar waves for fusion,” said Qin.

1 day ago · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
5 days ago · The experiments were performed using the Keda Space Plasma EXperiment (KSPEX), which is a linear magnetized plasma device with a vacuum chamber 5 m in length and 0.5 m in diameter (Jin et al., 2023; Liu et al., 2016). As shown in Figure 1, the plasmas were produced by a large area oxide cathode, which works in the steady state.
