Abstract
A noise immune gradiometer split shield coil for use in magnetic resonance etection, such as in Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupole Resonance (NQR). The coil is formed by a transmission line configured as a magnetic field gradiometer. The transmission line has a conductor which is electrically continuous through the coil, and a shield which is split at a position that causes the gradiometer to be electrically balanced. In this manner, the coil provides a high degree of internal shielding to reduce the effects of environmental noise pick-up. Such coils are also less sensitive to the effects of nearby conducting media.
