摘　　要：在间接驱动激光聚变研究中,平响应X射线二极管是X射线辐射能流测量的主要探测器。为了获得理想的平响应效果,采用传统方法需要花费大量时间优化二极管的复合滤片参数,为此引入了粒子群优化算法,将之用于平响应X射线二极管复合滤片参数的优化,该方法可更快捷、更准确地得到复合滤片的优化参数。提出了新的滤片组合方式,并优化其平响应特性,得到了比传统滤片组合更优的参数配比。该项工作为平响应X射线二极管复合滤片参数的寻优提供了一种更高效的方法。In the study of indirectly driven laser fusion,the flat response X-ray diode is the main detector for themeasurement of X-ray radiation energy flux.To obtain ideal flat response effect,it usually costs a lot of time tooptimize the composite filter parameters of the detector.In this paper,the particle swarm optimization algorithm isdeveloped and applied to optimize the parameters of compound filter of flat response X-ray diode.Compared with theprevious work,the method developed in this paper can get the optimized parameters of composite filter more quicklyand accurately.On this basis,this paper proposes a new filter combination mode,optimizes its flat responsecharacteristics,and obtains a better parameter ratio than the traditional filter combination.The work in this paperprovides a more efficient method for searching the parameters of the composite filter of the response X-ray diode.
