本年度主要完成了初始裂变产物鉴别技术研究项目中低气压高分辨气体电离室加工装配工作。探测器设计主要考虑了电场均匀性和入射窗材质及密封两个关键问题。氮化硅入射窗是此探测器设计关键的材料部件,对探测器的能量分辨及工作状态影响重要,为此开展了氮化硅入射窗承压能力测试。氮化硅入射窗规格为3×3阵列布局,有效面积尺寸为10 mm×10 mm,厚100 nm,经测试能承受
This year mainly completed the initial fission product identification technology research project in low-pressure high-resolution gas ionization chamber processing and assembly work. The detector design mainly considers the electric field uniformity and the incident window material and sealing two key issues. Silicon nitride entrance window is the key material component of the detector design, which has an important influence on the energy resolution and working status of the detector. For this purpose, the pressure-bearing capability of the silicon nitride entrance window was tested. Silicon nitride entrance window specifications for the 3 × 3 array layout, the effective area size of 10 mm × 10 mm, thickness 100 nm, the test can withstand
