| Abstract: | According to the target chamber structure and shooting mode of SG-Ⅲ laser facility, a static X-ray imaging system (SXI) has been successfully developed based on the principle of pin-hole imaging. This system uses the imitated target for off-line targeting, and can be adjusted on-line, with the regulation accuracy of 81 m and 40 m. The pinhole component and filter component can be changed automatically, which realizes fast online aiming and running in vacuum environment. The displacement and stress were calculated using the software ANSYS to ensure the reliability of this system. Laser targeting evaluation of the system equipped with X-ray CCD has been conducted on SG-Ⅲ laser facility. The result shows that the system reaches the requirement of the SG-Ⅲ laser facility. |
