Upon the totally unexpected theft of the original 600 MHz HTS insert that occurred in December 2011, we were forced to examine our entire 1.3 GHz NMR Magnet program anew and determined that a combination of a 600 MHz LTS magnet and a 700 MHz HTS insert (H700) would yield a 1.3 GHz LTS/HTS magnet that meets the technical specifications consistent with economic constraints. Although this new 700 MHz HTS insert still comprises, as H600, a YBCO inner coil and a Bi2223 outer coil, it incorporates innovative design features. In addition to presenting the major design parameters of the new H700, we discuss here its key electromagnetic and mechanical issues.
