UnverifiedHigh-temperature superconducting materials (such as REBCO coated conductors) can maintain the superconducting state above about 20 K, greatly reducing cooling costs, and have a higher critical magnetic field, allowing magnets to be made more compact.71% similarUnverifiedThe high-temperature superconducting magnet technology used by CFS can produce a magnetic field strength approximately twice that of conventional superconducting magnets (approximately 20 tesla), theoretically allowing the device volume to be reduced to about 1/40 that of ITER.70% similarUnverifiedThe tokamak is currently the most mainstream form of magnetic confinement fusion device, using strong magnetic fields to confine plasma at hundreds of millions of degrees Celsius in a toroidal chamber to induce fusion reactions between deuterium and tritium.69% similarUnverifiedCFS is known for its high-temperature superconducting magnet technology, and its SPARC and ARC roadmaps depend on breakthroughs in miniaturizing high-temperature superconducting magnets.68% similarUnverifiedThe vast majority of known magnetic semiconductors can only maintain magnetic ordering at temperatures far below room temperature, which is the technical bottleneck preventing their practical application.67% similar
