Physics developed powerful little magnets for thermonuclear reactors

Researchers at the Princeton Plasma Physics Laboratory have come up with a way to create powerful magnets of small size for the currentac. High-temperature superconductive magnets are made of material that produces electricity with little or no resistance at all at higher temperatures than before.

For their magnet, scientists used superconductive cable on a circular heart. The wires created by this technology do not require conventional epoxy and glass fibre insulation to conduct electricity. This allows for a more dense wrapping and the creation of a larger magnetic coil of smaller size.

High-temperature superconductive magnets have a number of advantages over copper wire magnets, explain the designers. They can be used longer without interruption because they don't heat up so fast. However, superconductor wires can transmit the same amount of electrical current as copper wire is many times larger, creating a stronger magnetic field.

Physicists believe that new magnets will help reduce the size of the currentacca, increasing productivity and reducing the cost of constructing a thermonuclear reactor.

Tokamaks are sensitive to conditions in their central areas, including the size of the central magnet or solenoid, the shielding, and the vacuum vessel. Much depends on the center. So if you can reduce something in the middle, you can reduce the whole machine and lower costs by theoretically increasing productivity.
