Some of the technological applications of superconductivity include: * the production of sensitive magnetometers based on SQUIDs * fast digital circuits (including those based on Josephson junctions and rapid single flux quantum technology), * powerful superconducting electromagnets used in maglev trains, Magnetic Resonance Imaging (MRI) and Nuclear magnetic resonance (NMR) machines, magnetic confinement fusion reactors (e.g. tokamaks), and the beam-steering and focusing magnets used in particle accelerators * low-loss power cables * RF and microwave filters (e.g., for mobile phone base stations, as well as military ultra-sensitive/selective receivers) * fast fault current limiters * high sensitivity particle detectors, including the transition edge sensor, the superconducting bolometer, the superconducting tunnel junction detector, the kinetic inductance detector, and the superconducting nanowire single-photon detector * railgun and coilgun magnets * electric motors and generators〔Fischer, Martin. (New Path to 10 MW ) ''Renewable Energy World'', 12 October 2010. Retrieved: 14 October 2010.〕 == Magnetic Resonance Imaging (MRI) and Nuclear Magnetic Resonance (NMR)== The biggest application for superconductivity is in producing the large volume, stable, and high magnetic fields required for MRI and NMR. This represents a multi-billion US$ market for companies such as Oxford Instruments and Siemens. The magnets typically use low temperature superconductors (LTS) because high-temperature superconductors are not yet cheap enough to cost-effectively deliver the high, stable and large volume fields required, notwithstanding the need to cool LTS instruments to liquid helium temperatures. Superconductors are also used in high field scientific magnets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「technological applications of superconductivity」の詳細全文を読む スポンサード リンク
