强激光与固体靶相互作用所致硬X射线的辐射安全初步研究
Preliminary Study on Hazard of Hard X-ray Radiation Produced in Interaction Between High Intensity Laser and Solid Target
摘要
Abstract
With the rapid development of laser technology, a number of high intensity laser devices are emerging in China and other countries. At the same time, the hazard induced by the radiation produced in the interaction between high intensity laser and solid target has gradually been observed and attention has been paid to this hazard. In this paper, the physical process and character of the interaction between laser with high intensity and solid target were analyzed through extensive research. The parameters of the radiation sources were discussed, including the energy conversion efficiency of laser-electronic, thermal electron energy spectrum and electron temperature, the energy spectrum of hard X-ray produced by thermal electron, etc. Then the primary assessment of the resulting X-ray dose due to the interaction between the laser and the target with the laser intensity in 1014 to 1020 W/cm2 were obtained. Finally, as an example the preliminary design of the radiation safety system for a laser device at Stanford Linear Accelerator Center ( SLAC ) was described. The results of this study provide a reference for the radiation safety assessment and safety system design for strong laser devices.关键词
