A metal wire is arranged in the discharge bracket; the pulse current detection coil is used for detecting a discharge loop current; the capacitive voltage divider is used for detecting the waveform of the pulse high voltage; the high-speed oscilloscope is used for displaying waveforms of the pulse large current and the pulse high voltage; and the ultra-high-speed camera is used for acquiring an image of metal wire electrical explosion plasma optical radiation. According to the method and the device, quantitative characterization of the light radiation uniformity of the strong pulse flash light source can be realized so that synchronous detonation of large-area photosensitive explosives can be realized.

Description

technical field [0001] The invention relates to the technical field of pulse power, in particular to a detection system and detection method for the uniformity of optical radiation of metal wire electric explosion plasma. Background technique [0002] In pulse power technology, the equivalent pulse load is often used to simulate the thermo-mechanical effect produced by intense pulsed X-rays on the surface of the shell structure. At this stage, the photosensitive explosive loading method is the most ideal loading method. It uses a strong pulse flash to instantly detonate the photosensitive explosive sprayed on the surface of the shell structure, and applies a pulse load to the shell structure to simulate the thermo-mechanical effect of strong pulsed X-rays. This method can more realistically simulate the pulse load effect caused by strong pulsed X-rays. It has many advantages such as good surface loading simultaneity, regular load cosine distribution, small load amplitude, an...
