Abstract
Neutron-induced background has been studied in various components of the TIN.TIN detector, which is under development for the search of Neutrinoless Double Beta Decay in 124Sn. Fast neutron flux ∼106 n cm-2s-1 covering a broad energy range ∼0.1 to ( ∼18 MeV) was generated using 9Be(p,n)9B reaction. In addition, reactions with quasi-monoenergetic neutrons were also studied using 7Li(p,n)7Be reaction. Among the different cryogenic support structures studied, Teflon is found to be preferable compared to Torlon as there is no high energy gamma background Eγ > 1 MeV) . Contribution of neutron-induced reactions in nat, 124Sn from other Sn isotopes (A = 112–122) in the energy region of interest, namely, around the Qββ of 124Sn (E ∼ 2.293 MeV), is also investigated.
