在静电加速器上作能量校正和激发曲线等实验时,需要频繁地改变束流能量,频繁地改变分析磁铁的磁场,测磁工作常常是大量的,这就要求测磁仪能给出信噪比比较高的核磁共振信号,使搜索共振信号容易,测量迅速准确,同时又要求操作简便,能够遥控。为此,我们研制了一台74-614晶体管核磁共振测磁仪,以适应物理实验工作的需要。
In the electrostatic accelerator on the energy correction and excitation curves and other experiments, the need to frequent changes in beam energy, frequent changes in the analysis of the magnetic field of the magnetometer is often a lot of work, which requires the magnetometer can give the signal to noise ratio Higher NMR signals make it easy to search for resonant signals, measure quickly and accurately, and at the same time require easy operation and remote control. To this end, we developed a 74-614 transistor NMR magnetometer to meet the needs of the physical experiment.
