Abstract

In 2008, the Phase 3 program to complete a 1.3 GHz (30.5 T) NMR magnet started at the Francis Bitter Magnet Laboratory, Massachusetts Institute of Technology. It comprises two sub-phases, 3A and 3B. In Phase 3A, a 600 MHz high temperature superconductor (HTS) insert magnet (H600) will be designed, constructed, and operated in the bore of a 500 MHz low temperature superconductor (LTS) background magnet. This will be followed by Phase 3B, in which the H600 will be combined with a 700 MHz LTS background magnet to complete a 1.3 GHz NMR LTS/HTS magnet. This paper presents and discusses design issues for two conductor options for H600: BiSCCO-2223 (Bi2223) and coated-YBCO or its variants, here designated as YBCO. For each conductor option, we focused on the following issues: (1) elastic and thermal properties; (2) critical current vs. field performance; (3) splice and index heat dissipations; (4) mechanical and thermal stresses; and (5) protection.

We thank the National Center for Research Resources, the National Institute of Biomedical Imaging and Bioengineering, and the National Institute of General Medical Sciences for support of this 1.3 GHz LTS/HTS NMR magnet project. We also thank the late Emanuel S. Bobrov and Prof. Haigun Lee (FBML: 1995–2005, currently at Korea University) both for their crucial contributions to the successful conclusions of Phases 1 and 2.
