Description
Technical Field
The utility model relates to a plasma physics and nuclear detection technical field especially relate to a coaxial measurement system of many radiation sources of superstrong laser drive.
Background
The research on the interaction between the intense laser and the plasma requires the diagnosis of various secondary radiations generated by laser targeting, including the spatial distribution of transmitted laser after targeting, the spatial distribution and energy spectrum of charged particles generated by targeting, gamma ray energy spectrum, and the like. The super laser is incident to the target surface and ionizes the target substance, thereby generating forward accelerated super-thermal electrons; these hyperthermo-electrons are transported in the target and emitted from the back of the target, thereby generating a charge separation field and a self-generated magnetic field. The generated charge separation field can accelerate ions, and the presence of the self-generated magnetic field can constrain the electron beam and the motion pattern of the ions that accompany the acceleration. Meanwhile, the electron beam moves in the plasma body and can excite bremsstrahlung X rays, characteristic X rays, higher harmonics and the like. These rich physical phenomena are difficult to give analytical expressions, so we are more about obtaining relevant information from numerical simulation and experimental research.
As can be seen from the foregoing physical processes, both ion acceleration and X-ray generation are dependent on electrons. Therefore, if the parameters of ions, X-rays and electrons emitted from the same azimuth angle can be diagnosed, the conversion efficiency of electrons to ions and X-rays can be analyzed, and the physical mechanism can be accelerated. At present, two main diagnostic methods are available for laser-accelerated multiple radiation sources, one is to place the detector at different azimuth angles, but the correlation between the diagnosed ions and X-rays and the diagnosed electrons is not strong. Therefore, the relationship between the accelerated ions and the excited X-rays and the electrons cannot be directly reflected. The other method is to measure physical parameters of the multiple radiation sources by adopting a mode of exciting the multiple radiation sources for multiple times at the same angle in order to obtain more relevant physical quantity data; however, this measurement method also affects the understanding of the physical process of the laser target due to the inconsistent plasma radiation parameters radiated each time the plasma is excited. It can be seen that the existing diagnosis mode can not carry out single coaxial measurement on multiple radiation sources, and the measurement consistency and accuracy are greatly influenced.
