    Applications

    Of superconductivity

    Maglev, the fastest train in the world, uses superconductors.<br/>Courtesy Central Japan Railway CompanySuperconductors are already used in many fields: electricity, medical applications, electronics and even trains. They are used in laboratories, especially in particle accelerators, in astrophysics with the use of bolometers, in ultrasensitive magnetic detectors called SQUIDs, and in superconducting coils to produce very strong magnetic fields.


    However, they need to be cooled to very low temperatures, which restricts their use in our everyday life. But new applications are already operational in laboratories and will be able to spread to our cities and our homes if the cooling process becomes less expensive or, better, if we discover superconducting materials that do not require any cooling. If this happens, we can expect an actual revolution in energies and environment on the one side, and transportation and computer science on the other.
