在文献[1]中我们曾报导了402型电子静电加速器的调试工作。一年来,这台加速器运行了一千二百多小时。在运行期间,我们对加速器的性能进行了考验。实践证明,402型电子静加速器是辐射化学研究中的一个很好的人工电子辐射源,使用它可以做出一些有用的结果。在加速器运行一年中也发现了一些问题,使用过程中也发生了不少故障。这些故障反映 In [1] we reported on the commissioning of the Model 402 Electrostatic Accelerator. Over the past year, this accelerator has operated for more than 1,200 hours. During the run, we tested the performance of the accelerator. Practice has proved that, 402 Electron Static Accelerator Radiation Chemistry is a good source of artificial electron radiation, use it to make some useful results. Some problems have also been found during the year of accelerator operation, and many failures have taken place during the operation. These failures reflect
