40 T class hybrid magnet system

Athermal and Isothermal Martensitic Transformations Induced at Room Temperature by Ultra High Magnetic Field

“…It should be noted that the duration of the pulse is larger by three orders of magnitude than those previously used in the Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jp4:1997559 Table 1 Alloy composition, nose-temperature, T,, marteniste volume eaction , f;,, induced by pulse magetic field of 20 MAIq and martensite volume fraction , f, induced by holding under steady magetic field of 17.5 M N m for 2h.. [4,6,7]. Figure 3 shows the structure of a hybrid magnet with 40 T (32 W m ) class, which was constructed several years ago in our institute and has being operated since then [2,3,4]. The basic principle of this hybrid magnet is to combine the outputs of superconduction magnet and water-cooled magnet; the inner water-cooled magnet is able to generate an incremental field of 17.9 W m in a clear bore of 50 mm diameter under a background field of 11.3 MA/m generated by the outer superconduction magnet.…”
