Probe head for an NMR spectrometer |
摘要 |
<p>A nuclear magnetic resonance (NMR) probe head for use in a room temperature bore of a superconducting NMR magnet cryostat for investigation of generally room temperature samples comprises a radio frequency (RF) receiving coil, a receiving coil preamplifier connected to the receiving coil, at least one additional coil and cryogenic means connected to the RF receiving coil, to the receiving coil preamplifier, and to the at least one additional coil for keeping the RF receiving coil, the preamplifier and the additional coil at a cryogenic temperature. The apparatus is improved in that at least one additional preamplifier is connected to the additional coil and to the cryogenic means the cryogenic means keeping the additional preamplifier at a cryogenic temperature. The apparatus exhibits improved performance and increased flexibility. <IMAGE></p> |
