We have developed an ESR spectrometer using a specially designed gyrotron, GTROTRON FU-E,as the radiation source that can operate a wide frequency range in millimeter wave region (65-135 GHz).GYROTRON FU-E,optimized for use in an ESR spectrometer, in the frequency range from 65 GHz to 195 GHz was developed in Fukui University.This is the first application of gyrotrons to ESR measurements.Preliminary measurements on the frequency and amplitude stabilities of the gyrotron is performed, and those stabilities are more than 5*10^<-5> and 2%, respectively.The results suggest that they are appropriate for the common ESR experiments.Measurement of ESR signal with single crystal and polycrystalline DPPH samples confirms the normal operation of the spectrometer.Inprovements are underway to enhance the sensitivity of the spectrometer and to allow measurements at still higher frequencies.

我们研制了一台以GTROTRON FU-E回旋管为辐射源的ESR谱仪，它能在毫米波范围内工作（65-135 GHz）.GYROTRON FU-E，优化用于ESR光谱仪，福井大学开发了频率范围从65 GHz到195 GHz的回旋管。这是回旋管首次应用于ESR测量。对回旋管进行了频率和振幅稳定性测试，稳定度分别达到5 × 10 ~（-4）和2%以上<-5>，对DPPH单晶和多晶样品的ESR信号测量结果表明，该谱仪工作正常，目前正在进行改进，以提高谱仪的灵敏度，使其能在静止条件下进行测量更高的频率
