The analog computation and contrast test of leaked electromagnetic noise in the klystron corridor

为确定泄漏噪声源的特性及位置 ,对国家同步辐射实验室速调管走廊泄漏电磁噪声进行了模拟计算 ,给出了调制器高频泄漏噪声的计算方法和计算公式。在模拟计算的基础上进行了现场的对比测试 ,对比测试结果显示了模拟计算的合理性 ,从而为抑制走廊的噪声泄漏提供了理论基础。

In order to obtain a better understand of the characteristics and location of noise source, the leaked electromagnetic noise in the klystron corridor of NSRL has been analogously calculated. The computational method and formula of high frequency leaked noise of the modulator were given. On-the-spot contrast tests have been made on the base of analog computation. The contrast test results show reasonableness of analog computation and whereby offer a theoretic base for reducing noise leakage in corridor.
