ABSTRACT:
Improved superconducting coils for a nuclear magnetic resonance probe use capacitive elements that are located in regions further from an active sample volume than magnetic field generating elements to which they are electrically connected. The sample volume is a substantially oblong shape, and the magnetic field generating elements run substantially parallel to the major axis of the shape, while the capacitor elements run perpendicular to the major axis. Gaps between the capacitor elements, and the width of the elements themselves, may increase toward the outside of the coil to minimize electrical discharge. The variation may be according to a monotonic, possibly linear, function. Discharge may also be minimized by using a dielectric cover that, together with a coil substrate, encloses the coil.
