Method to fabricate split coaxial line uhf probes for high-resolution NMR experiments.

A conventional Helmholtz coil used in a uhf high-resolution NMR probe is usually constructed from copper or silver bands instead of thin wires. This paper proposes a novel probe fabrication process by which the entire tank circuit of the probe can be etched or cut out from a piece of copper foil. A balanced structure with split coaxial line as rf feeders is illustrated. [ABSTRACT FROM AUTHOR]
