As a component of Phase-2 LTS/HTS NMR magnet of a 3-phase program to complete a 1-GHz LTS/HTS NMR magnet by 2009, an HTS insert magnet has been assembled from 48 double-pancake (DP) coils, each wound of high-strength Bi-2223/Ag/stainless steel composite tape. The paper describes the design and actual parameters; and preliminary performance results of the insert. The results include: 1) voltage vs. current data of double pancakes; and 2) splice resistances between adjacent double-pancake coils.
