Abstract：Laser fusion physics will produce a large number of electromagnetic pulse radiation, the electromagnetic pulse spectrum is wide and the intensity is high, it will be caused different degrees of impact on the normal operation and precision measurement of the diagnostic equipment. In order to study the characteristics of the electromagnetic pulse. To provide a basis for the mechanism of research and optimization of protective measures. This experiment, in the SG Ⅲ host device on. And the antenna diagnosis system is in the chamber inside and outside, collecting the electromagnetic pulse signal. This article analyzes the target of indoor small discone and collected signals, the rectangular antenna and two antenna measured time domain signals match quite well in characteristic peak position, the measured spectrum also contains the largest oscilloscope frequency domain values, and the image clearly shows the four processes of the interaction between the laser and the black-cavity target.
