Development of Advanced High-Field Magnets at the Tsukuba Magnet Laboratory

The Tsukuba Magnet Laboratory (TML) is one of the largest high-field user facilities in the world, constantly providing domestic and international users with steady fields of 30 to 35 T. TML is featured as a Center of Excellence on the development of superconducting magnets, where a recently developed 920 MHz NMR magnet is generating extremely uniform fields at 21.6 T for biological measurements. Also, new kinds of superconducting magnets have been developed that produce uniform magnetic force fields characterized by constant grad (B2).
