Abstract
A nuclear magnetic resonance apparatus including a magnet generating a static magnetic field in a first region containing materials to be analyzed. The magnet generates zero static magnetic field in a second region. The magnet has generally homogeneous magnetization along a longitudinal axis and is magnetized substantially perpendicular to the axis. The apparatus includes means for generating a radio frequency magnetic field in the first region for exciting nuclei of the materials. The means for generating the radio frequency magnetic field includes an antenna disposed within the second region. The apparatus includes means for receiving a nuclear magnetic resonance signal from the excited nuclei. In a preferred embodiment, the means for generating and means for receiving include an antenna at least partially disposed within the second region. In a specific embodiment, the antenna consists of wire coils wound in planes perpendicular to the longitudinal axis of the instrument. A high permeability ferrite is disposed inside the wire coils of the antenna.
