Development of single frame and double-channel X-ray framing camera system for SG-Ⅲ laser facility

According to the operation mode and target chamber structure of SG-Ⅲ laser facility, a single frame X-ray framing camera system with double channels is successfully designed. The imaging system mainly consists of a pin-hole camera, a gated MCP framing camera and a scientific grade visible light CCD. The pin-hole diameter is 10 m, the and magnification is 5. The single frame format of the system is 13 mm36 mm, and exposure time is adjustable from 0.5 ns to 10 ns. Performance evaluation is conducted on SG-Ⅲ laser facility, and the results show that the system completely meets the requirement of SG-Ⅲ laser facility. Compared to the traditional X ray imaging system, which mainly consists of pin-hole camera and X-ray CCD, the signal-to-noise ratio and spatial resolution are better.
