NMR FREQUENCY LOCKING CIRCUIT |
摘要 |
An NMR locking mechanism for use with not only electromagnets, superconducting magnets and permanent magnets, but also with ultrahigh energy product magnets such as neodynium. The circuit utilizes a single conversion superheterodyne receiver with a phase locked loop that forms a locking mechanism that depends upon a variable frequency. The resonant frequency of the nuclei is compared to a variable excitation frequency which is adjusted to maintain a control frequency with one unique value of the control frequency being zero at lock. |
