国家同步辐射实验室速调管走廊泄漏电磁场的计算

国家同步辐射实验室速调管走廊内的高频微波泄漏,严重影响着速调管走廊内的微波通讯.为了降低速调管走廊的电磁辐射场,抑制走廊的电磁噪声,必须要确定噪声源的位置,而对于空间复杂的泄漏场,噪声源的位置很难确定,我们可以通过测定空间的泄漏场,经过计算,反过来确定噪声源的位置,进而研究抑制走廊电磁噪声的办法.给出了速调管走廊泄漏电磁场的计算方法、计算公式及现场的对比测试.

Calculation of Leaked Electromagnetic Field in Gallery of Klystron of NSRL

The HF microwave leak in the gallery of klystron of NSRL affects microwave communication greatly. In order to reduce electromagnetic radiation field and to restrain electromagnetic noise, it is necessary to locate the noise source. But for the complicated leaked field, it is difficult to locate the noise source. We can measure the leaked field and calculate it, so as to locate the radiant noise source and study the method of reduction the electromagnetic noise. This article gives the method and formulas of calculating of electromagnetic field, and also On the spot contrast test.
