Overhead Shielding of Small Experimental Area for Intermediate Energy Heavy Ion Reaction
-
摘要: 在考虑了中能重离子反应出射中子天空反射效应的基础上,以4×1011ions/s、100MeV/u12C+Cu(厚靶)反应为例,计算出重离子物理实验小区需设置的顶部屏蔽混凝土厚度d=1.1m. Based on considering the skyshine and the distribution of neutrons emitted from the reaction of 100MeV/u 12 C+Cu, the concrete shielding thickness of overhead shielding of the small experimental area in the physical experimental hall is calculated, which would be about 1.1m.Abstract: Based on considering the skyshine and the distribution of neutrons emitted from the reaction of 100MeV/u 12 C+Cu, the concrete shielding thickness of overhead shielding of the small experimental area in the physical experimental hall is calculated, which would be about 1.1m.
