摘要:

对$^{124}$ Sn中$0νββ$衰变的辐射背景进行了研究。为此目的,TIFR安装了TiLES设置。用快中子活化技术研究了TiN、TiN探测器材料的中子感生本底。使用MC模拟估算了INO洞穴中岩石的SF和($α, n$)相互作用产生的中子通量($E_n\leq15$ MeV)。本文提出了一种双层硼化石蜡(20 cm)+铅(5 cm)的复合屏蔽,用于降低中子注量率。

英文摘要:

Radiation background studies pertaining to $0νββ$ decay in $^{124}$Sn have been carried out. A TiLES setup has been installed at TIFR for this purpose. Neutron-induced background is studied in the TIN.TIN detector materials using fast neutron activation technique. The neutron flux ($E_n\leq15$ MeV) resulting from SF and ($α, n$) interactions for the rock in the INO cavern is estimated using MC simulations. A two layer composite shield of borated paraffin (20 cm) + Pb (5 cm) is proposed for the reduction of neutron flux.
