specific Embodiment approach 1

[0007] Specific implementation mode 1: This implementation mode is an application of a tantalum-uranium thin film on a black cavity. The tantalum-uranium thin film is used as a black cavity inner lining protection layer, or is applied on a black cavity as an energy conversion layer.

[0008] The tantalum-doped uranium thin film is used as the lining protective layer. While protecting the energy conversion layer of the uranium black cavity, the tantalum-doped uranium also has better interface bonding force and chemical compatibility, and higher energy coupling efficiency.

[0009] Tantalum-doped uranium film is used as the energy conversion layer. Compared with Au, tantalum-doped uranium has higher laser-X-ray conversion efficiency and lower M-band X-ray yield. Compared with U, it has outstanding chemical stability and structural reliability. .

specific Embodiment approach 2

[0010] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the tantalum content in the tantalum-doped uranium thin film is 3 at.%-12 at.%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0011] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the tantalum-doped uranium thin film is prepared by double-target magnetron sputtering co-deposition method. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to an application of a tantalum-doped uranium film in a black cavity, belonging to the technical field of laser fusion engineering, and particularly relating to an application ofa tantalum-doped uranium film. The invention aims to solve the problem that in the existing uranium black cavity, the gold lining laser-X-ray conversion efficiency is insufficient, and the physicallyexpected non-lining uranium black cavity is poor in chemical stability, and the structure of the black cavity is not stable. The tantalum-doped uranium film is used as a black cavity lining protective layer or is applied to a black cavity as an energy conversion layer. The tantalum-doped uranium film has the advantages of being good in antioxidant corrosion resistance; as the lining protection layer, having the better interface bonding force and chemical compatibility, and higher energy coupling efficiency while protecting the uranium black cavity energy conversion layer; as the energy conversion layer, having the higher laser-X-ray conversion efficiency compared with Au and lower M-band X-ray yield, and being outstanding in chemical stability and structural reliability.

Description

technical field [0001] The invention belongs to the technical field of laser fusion engineering, and in particular relates to the application of a tantalum-doped uranium thin film. Background technique [0002] Indirectly driven laser inertial confinement fusion is an important direction of controlled nuclear fusion research, which places people's good wishes on solving the problem of human energy demand once and for all. The black cavity is an important part of indirectly driving laser inertial confinement fusion. It plays a role in converting laser energy into X-rays, which is directly related to the conversion efficiency of driver energy and X-rays and the spatial symmetry and cleanliness of the radiation field. [0003] For a long time, Au has been regarded as the main candidate material of the black cavity wall because of its high atomic number (Z) and excellent chemical stability. Compared with the traditional gold black cavity, studies have shown that metal U as the ...
