Hf - receiving coil arrangement for a nmr - resonator with macroscopically homogeneous distribution of the conductor structures

摘要

A nmr - resonator for the reception of hf - signals on desired resonance frequencies of a measuring sample in a an origin of coordinates (x, y, z = 0) examination volume, which is arranged with a device for generating a homogeneous magnetic field b φ 0 φ in the direction of a z - axis, wherein between the dollar f1 superconductive conductor structures on a in the z - the direction of translations - invariant (= z - invariant) surface in the radial distance from the measuring sample are arranged, is characterized in that, on the z - invariant surface, in addition, a compensation - arrangement which is provided at least up to values of dollars f2, dollar i3 of the smallest distance between the sample and the compensation - arrangement is that the compensation - arrangement further superconductive conductor structures, which comprises hf - moderately of hf - resonator are decoupled, that the conductor structures of the compensation - arrangement and of the hf - resonator consists of individual surface sections containing superconducting structures (= "z - structures") are composed in the z - invariant surface, in each case over the entire length in the z - the direction of the conductor structures of the compensation - arrangement and of the hf - resonator, and the superconducting structures are arranged in such a way that in the case of a decomposition of the surface of the z - structures into a plurality of less than, equal to a large surface elements and upon the application of a homogeneous test magnet field along the surface normals of each surface element for all ..
