从核磁共振仪到电子自旋共振实验仪的改装

Transform a nuclear magnetic resonator to an electron spin resonator

介绍了将核磁共振仪改装成电子自旋共振实验仪的制作过程．实验弃用了原有的HZ811小型核磁共振中的永磁体，改用螺线管，并增加了专供电源，同时改变了边线振荡器的频率范围，实现了磁场强度从0·4T到0．0005T、对应频率从12～18MHz的范围到21～31MHz的转变，从而满足了电子自旋共振实验仪的实验要求．

The experimental process to transform a HZ811 nuclear magnetic resonator to an electron spin resonator was introduced. The permanent magnet on the HZ811 nuclear magnetic resonator was replaced by a solenoid with specific power source. The frequency range of margin oscillator was also changed. The magnetic field intensity changed from 0.4 T to 0. 000 5 T, corresponding a change of frequency range from 12--18 MHz to 21--31 MHz, which could meet the requirements of electron spin resonance experiment.
