β¦ Synopsis
The present period is one of rapid development and major extension of the technology for high resolution and solid state NMR spectrometer magnets. Programs which have already been initiated have as their objective proton frequencies of 1 GHz and greater, eventually requiring HTS superconductors. These magnets will contain inner coils containing HTS conductors, surrounded by a set of relatively large coils fabricated with metallic superconductors. These coils represent a major extension of the adiabatically stable magnet technology that has evolved to address the performance issues posed by this type of magnet. The developments which are desirable for these large magnets are identified to include tough epoxy, interface to and thermal performance of external reinforcement, and high strength -high current density metallic superconductor.

A new class of pathway-selective high-resolution gradient NMR experiments is introduced, in which the spatial evolution due to the magnetic field gradient is employed to discretely spatially modulate the pulse sequence as seen by the spins. For multiple quantum filtered experiments this approach ret
