Abstract：
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.
