Abstract: The applying background of radio frequency explosive magnetic flux compression generator requires that it hasa high radiation power, and the pulse spectrum should be in high frequency. Based on the inverse proportion of signal pulsewidth to the signal band, the way of both sides and axis detonation used in radio frequency explosive magnetic flux compressiongenerator are proposed to compress the pulse width and improve the signal frequency and pulse power。By comparing of axisdetonation and one side detonation, we can see that the output current pulse width can be compressed and the signal frequency and the pulse power can be increased by the way of axis detonation.
