摘要:

我们建立了一个中子校准设施的基础上,300毫居里的Am-Be源结合弱相互作用的大质量粒子候选人的暗物质的搜索。该装置用于研究CsI(Tl)晶体对Am-Be源中子引起的核反冲的响应,并将其与662 keVPDMATHABMM-射线对$^{137}$ Cs源康普顿散射产生的电子反冲的响应进行比较。用品质因数对核反冲和电子反冲脉冲波形鉴别(PSD)的测量结果进行了量化。与中子反应堆的类似结果的比较表明,使用Am-Be源的中子进行PSD测量校准的可行性。

英文摘要:

We constructed a neutron calibration facility based on a 300-mCi Am-Be source in conjunction with a search for weakly interacting massive particle candidates for dark matter. The facility is used to study the response of CsI(Tl) crystals to nuclear recoils induced by neutrons from the Am-Be source and comparing them with the response to electron recoils produced by Compton scattering of 662-keV $γ$-rays from a $^{137}$Cs source. The measured results on pulse shape discrimination (PSD) between nuclear- and electron-recoil events are quantified in terms of quality factors. A comparison with similar result from a neutron reactor demonstrate the feasibility of performing calibrations of PSD measurements using neutrons from a Am-Be source.
