Abstract
A broadband matching network for coupling a magnetic resonance probe to a preamplifier utilizes superconducting matching coils and superconducting locatable shields to detect very weak magnetic signals over a broad bandwidth. The superconducting matching coils and shields minimize signal loss in the matching amplifier. When used with a superconducting magnetic resonance probe, the circuit provides a significant broadening in bandwidth over that of the probe without loss of performance.
