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 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.
