4641098 Parallel single turn saddle resonator for nuclear magnetic resonance signal reception

Abstract

The capacitively shortened slotted line resonator or single turn saddle coil, as used in nuclear magnetic resonance signal reception, is modified by forming two axial slots from one end nearly to the opposite end through the center of the axial conductor bands. The resulting parallel arrangement of two inductor saddle loops is essentially transparent to rf magnetic fields orthogonal to its own rf magnetic field direction and orthogonal to the axis of the resonator, which allows for higher efficiency and sensitivity when two orthogonal saddle coils are employed in double resonance NMR experiments.
