Compared with the traditional process for preparing the cylindrical black cavity by turning and electroplating, the method is a novel black cavity preparation method, and the defects of the black cavity mandrel and the gold layer surface caused by the arc transition area of the complex-structure black cavity in the mandrel processing and the electric field effect in the electroplating process are avoided.

Background
In the research of indirect driving inertial confinement fusion, laser is converted into a low atomic number material target pill at the center of the black cavity through the cavity wall of the black cavity, so that the fuel at the center of the target pill reaches fusion conditions of high temperature and high density, and the method is one of the solutions for human science to utilize fusion energy. This requires that the radiation driven asymmetry of the black cavity is controlled below 1%. The traditional black cavity is a cylindrical cavity with two laser input holes at two ends, so that the radiation environment in the black cavity is improved, the laser coupling efficiency is improved, and the back share is reduced.
The traditional cylindrical black cavity preparation process generally adopts a precision turning mandrel, a plating layer of black cavity material is plated through an electroplating process, after secondary precision turning processing, the mandrel material is removed through an acidic or alkaline solution, and a hollow cylindrical black cavity is obtained. The traditional process can self-prepare a cylindrical black cavity, but for the preparation of an orthorhombic ellipsoidal black cavity, if the traditional preparation process is adopted, the following problems exist:
(1) Due to the limitation of the radius of the cutter, when the mandrel of the ellipsoidal cavity is processed, a larger arc transition area is generated at the intersecting position of the orthorhombic ellipsoidal cavity, so that the inner wall of the black cavity is not in a complete ellipsoidal shape after corrosion, the difficulty of multi-ring injection and inner-outer ring power ratio regulation and control can be caused, the asymmetry of radiation driving is increased, and the radiation environment in the black cavity can not be effectively improved.
(2) In the electroplating process, the intersecting position of the orthorhombic ellipsoidal cavity is difficult to effectively plate a black cavity material layer due to the existence of an electric field effect, so that the wall of the black cavity is incomplete.
