Abstract

A nuclear magnetic resonance (NMR) magnet comprised of low- and high-temperature superconducting (LTS/HTS) coils has been built and operated at a frequency of 360 MHz. The magnet operates at 4.2 K with the LTS background coil operated in persistent mode, while the HTS insert is in driven mode. The HTS insert is an assembly of 50 double pancakes, each wound with Bi-2223/Ag tape. The paper describes design and performance results of the LTS/HTS magnet.
