摘要: 在脉冲X射线辐射效应研究中，需要将时间维度信息结合到仿真模型中，进而实现基于时间能量联合方法的辐射效应数值模拟，同时也为瞬态脉冲辐照效应的仿真提供了一种思路。建立轫致辐射打靶模型，计算出射脉冲X射线能谱，得到脉冲X射线的时间能量联合谱，结合辐射对象的辐射效应仿真模型，获得氧化铝陶瓷试样在不同时间及不同入射深度处的能量沉积。Abstract: In the study of pulsed X-ray radiation effect, it is necessary to integrate the information of time dimension into the simulation model, and then realize the numerical simulation of radiation effect based on time energy joint method, which provides a research idea for the simulation of transient pulsed radiation effect. The model of bremsstrahlung shooting is established, and the energy spectrum of outgoing pulsed X-ray is calculated. Combined with the radiation effect simulation model of radiation object, the energy deposition of alumina ceramic sample at different time and different incident depth was obtained.
