Abstract:
1. A nuclear magnetic resonance probe coil used in a nuclear magnetic resonance apparatus comprising: a plurality of substrates which are arranged in parallel, each substrate having a first surface and a second surface opposite said first surface; a plurality of one turn coils made by a superconductive thin film, wherein one of said plurality of one turn coils is formed on the first surface of each of said substrates, wherein in one part of each of said one turn coils is made an opening; a plurality of normal metal thin films formed at the corresponding position of the opening of said one turn coil on the second surface of each of said substrates; a plurality of normal metal connecting wires connected by resistive connection to said normal metal thin films, wherein said connecting wires connect said one turn coils to each other through an edge of said substrates so that said one turn coils form a receiving solenoidal coil; a plurality of spacers which are arranged in parallel between each of said plurality of substrates and under a lowest one of said plurality of substrates; a transmitting probe coil which is assembled by normal metal transmittal probe coil components which are supported by holes formed in each of said substrates and spacers, and which surrounds the receiving solenoidal coil; an upper protecting board arranged on a highest upper spacer and an upper component of said transmitting probe coil; and a lower protecting board arranged under said lowest spacer and a lower component of said transmitting probe coil, wherein a hole for a sample tube is provided through the upper protecting board, all substrates, all spacers and the lower protecting board at an inner part of said plurality of one turn coils.
