本文对法国Grenoble强磁场实验室的有关强磁场磁铁方面的最新发展作了简要论述。用一个内层为复合螺管、处层为比特线圈所组成的10兆瓦电阻性磁铁,在5厘米孔径内已获得22.3T的磁场。理论上的最佳计算表明,用一个10兆瓦复合螺旋形磁铁和一个13T超导线圈组合,即能在3厘米孔径内得到约39T的稳定场。 This article gives a brief account of recent developments in the field magnetics of the Grenoble Strong Magnetic Field Laboratory in France. A 10-megawatt resistive magnet consisting of a bit coil at the inner layer of a composite solenoid and a 22.3-T magnetic field has been obtained within a 5-cm aperture. The theoretical best calculation shows that a combination of a 10 MW composite spiral magnet and a 13T superconducting coil results in a stable field of about 39T within a 3cm aperture.
