The very best high field performance attainable in Nb3Sn is provided by OST’s RRP wire. A focused development effort over the last 10 years has resulted in a 3-times increase in critical current density at 20 tesla in this wire. This performance has enabled two world-record setting magnets: a 950 MHz NMR magnet, and a 16 tesla dipole magnet.
OST has now scaled up this state-of-the-art conductor to commercial production. For applications demanding the very best high field performance, RRP may provide the most cost effective conductor. A sampling of commercially available standard size and performance is shown in the data table. Higher performance material is available for some applications, inquiries are welcome.
