Title:
核磁気共鳴装置用のNMRプローブ
Document Type and Number:
Japanese Patent JP4673188
Kind Code:
B2
Abstract:
A NMR probe which causes only a minimum disturbance to magnetic-field uniformity, and which acquires a high resonant Q value. A detection coil 1 for detecting a nuclear magnetic resonance signal emitted from a sample 3 measured, and a compensation coil 4 composed of a superconducting material for compensating for inductance of the detection coil 1 are electrically connected in series with each other. Moreover, a tuning-dedicated variable capacitor 6 is connected to the detection coil 1 in series therewith, and a matching-dedicated variable capacitor 5 is connected to the compensation coil 4 in series therewith. Furthermore, a coaxial cable 9 is connected to both ends of the matching-dedicated variable capacitor 5. This configuration allows detection of the signal.
