Description
Technical Field
The invention relates to the technical field of high-energy density physics, in particular to a radiation impact target and a method for generating radiation impact waves with the speed of more than 100km/s in xenon.
Background
The radiation shock wave is widely existed in celestial systems such as supernova explosion, young stars, catastrophe stars, black holes and the like. Different from common shock waves, the radiation shock waves are characterized in that the radiation transport influences the hydrodynamic evolution process of the shock waves to a great extent. Radiation transport is highly coupled with hydrodynamic processes, so that the generation and propagation processes of radiation shock waves involve extremely rich physical phenomena. Experiments are carried out in a laboratory to research the evolution law of the radiation shock waves, so that the human can be helped to understand the related celestial phenomena, and the understanding of the human on the universe is further deepened. Advances in high power laser technology have made it possible to study radiated shockwaves in the laboratory. Experiments on radiated shock waves have been carried out on devices such as Nova, Omega, LULI2000, France, GEKKO-XII, Japan, and the like, in the United states. In these experiments, xenon gas is the most popular radiation shock wave propagation medium due to its high atomic number (with strong radiation re-emission effect), stable properties and adjustable density.
The speed of the radiant shock wave is the most important physical quantity characterizing the intensity of the radiant shock wave. On the one hand, theoretical studies show that the velocity of the radiation shock wave decreases as the xenon density increases. Therefore, in order to generate stronger radiation shock waves, the xenon density is required to be as low as possible. On the other hand, the main diagnostic means for acquiring the speed of the radiation shock wave is X-ray fluoroscopy. To obtain a sharp contrast radiation shock wave wavefront image, the xenon density is required to be as high as possible. The reasonable experimental design must be a compromise between the two, which not only meets the physical requirements, but also considers the diagnosis requirements. Besides, the problems of preparation, inflation and air retention of the shock wave tube, laser injection and the like need to be considered. However, some existing radiation impact targets cannot generate 100 high-speed radiation impact waves in xenon after the impact targets are filled with xenon, so that it is difficult to obtain a radiation impact wave front image with obvious contrast.
Disclosure of Invention
The present invention provides a radiation impact target and a method for generating a radiation impact wave with a velocity of 100km/s or more in xenon gas, which can generate a radiation impact wave with a velocity of 100km/s or more, so as to obtain a radiation impact wave front image with obvious contrast.
In order to solve the technical problems, the invention adopts the technical scheme that: a radiation impact target comprises an impact wave tube, a shielding case, an annular metal sheet, an ablation layer and an air storage chamber; one end of the shock wave tube is communicated with the gas storage chamber, the other end of the shock wave tube is communicated with one end of the shielding cover, and the other end of the shielding cover is open; the annular metal sheet is arranged at the end part of one end of the shock wave tube connected with the shielding case, and the ablation layer is arranged on the annular metal sheet. The nanosecond laser is applied to the ablation layer, and the heated material is scattered backwards to generate a forward driving force to drive the residual material to compress xenon gas in the shock wave tube inwards, so that the shock wave propagating in the shock wave tube is generated. The annular metal sheet filters X rays of a laser action target surface, and the impact wave tube is prevented from being heated in advance. The shield avoids interference of the residual laser light to the measurement. The shock wave tube constrains the shock wave to propagate within it.
