Patent ID: 7514922

Claim:
A magnetic resonance probe head, the probe head having dimensions defined in x, y, z directions of a rectangular coordinate system, the probe head for investigation of a test sample or of a test sample having a circular cross section in an xy plane, the sample being elongated in the z direction, the probe head comprising: a vacuum container; several RF resonator coils disposed in said vacuum container, said coils structured for cryogenic cooling and each being designed as a planar coil which is disposed parallel to the z direction, wherein all of said RF resonator coils have a larger extension in the x direction than in the y direction; and a central tube block disposed between said RF resonator coils, said central tube block having a test sample recess which is elongated in the z direction, wherein said central tube block partially delimits said vacuum container, said recess being outside of said vacuum container, said central tube block having a larger extension in the x direction than in the y direction in an area thereof disposed between said RF resonator coils.
