Boron-10 lined RPCs for sub-millimeter resolution thermal neutron detectors: Feasibility study in a thermal neutron beam
摘要:
介绍了基于阻性板室(RPC)的位置灵敏热中子探测器的实验可行性研究结果。探测器原型的特点是一个薄间隙(0.35 mm)的混合RPC与铝阴极内衬2 $μ$米厚的$^{10}B{_4}C$中子转换层富含$^{10}B$和浮法玻璃阳极。在垂直入射下,对于中子束($λ$ =2.5 $Å$)测量到${\approx}$ 6.2 ${\%}$的探测效率。空间分辨率优于0.5 mm FWHM。
英文摘要:
The results of an experimental feasibility study of a position sensitive thermal neutron detector based on a resistive plate chamber (RPC) are presented. The detector prototype features a thin-gap (0.35 mm) hybrid RPC with an aluminium cathode lined with a 2 $μ$m thick $^{10}B{_4}C$ neutron converter layer enriched in $^{10}B$ and a float glass anode. A detection efficiency of ${\approx}$ 6.2 ${\%}$ was measured for the neutron beam ($λ$ =2.5 $Å$) at normal incidence. A spatial resolution better than 0.5 mm FWHM was demonstrated.
