Experimental study of pulsed X-ray imaging based on wire load

Abstract

In order to carry out X-pinch related experimental research, a new one-day experimental circuit has been established on the side of Light-II Pulse Power Generator (250 kA/50ns) at China Institute of Atomic Energy. On the basis of retaining the original pumping laser capacity of the device, X-pinch related experimental research can be carried out at the same time. Two groups of X-pinch were driven by Light- II, one group was placed in the anode and the other group was placed in the reflux disk. The time difference was used to conduct the backlight imaging experiment of plasma distribution in the process of X-pinch self-explosion, and the sequence images of different times of X-pinch development were obtained. In the picture, the halo layer, pinch, implosion and final collapse dissipation of the plasma at the X-pinch point can be observed. The experimental results are helpful to further understand the physical mechanism of X-pinch plasma development. At the same time, X-pinch biological phase contrast imaging experiment was carried out, and high-resolution biological imaging pictures were obtained.
