Phase II of our three phase program to develop a 1 GHz High Resolution LTS/HTS NMR Magnet, entails the design, construction and testing of a 700 MHz LTS/HTS NMR magnet. Here we report on the design and construction of a 100 MHz HTS Insert magnet, its interface to a 600 MHz LTS magnet, and testing of the LTS/HTS assembly. Immersed in 4.2 K LHe at atmospheric pressure, the coils are independently powered with the HTS Insert operating at 116 A while the background LTS coil carries 235 A. Details of the mechanical, cryogenic and magnetic features of the system are presented.
