| 摘 要： | 初步探讨利用X射线成像反推核爆当量.建立特征环小孔几何模型,采用MCNP4C进行模拟,从模拟源面积,Ec的选取,环宽、等效温度及X射线入射角度的影响等方面对蒙特卡罗模拟进行讨论.在模拟时宜选取源面积S0=6.25π cm2、能量截断值Ec=2×10-8 MeV,需考虑能量响应和角度响应.对等效温度为1.4 keV和3.8 keV、X射线入射角度为0°,1°,2°,3°,4°,5°,6°的特征环小孔模型分别进行模拟,给出根据这些模拟结果反推核爆当量的具体方法.

| Abstract: | Using X-ray imaging to deduce equivalent of nuclear explosion is preliminarily discussed.A characterized ring pinhole geometry model is established.MCNP4C is used.The source area,determinaton of E_c,influence of ring width,equivalent temperature and incident angle of X-rays are simulated.It is poined out that the source area should be selected as S_0=6.25πcm~2 and E_c= 2×10~(-8) MeV.Energy response and angle response should be considered.Characterized ring pinhole models at equivalent temperatures 1.4keV and 3.8keV and at incident angles 0,1,2,3,4,5,6 degree are simulated. |
