“…In the range from 40 keV to 140 keV, it is in a good agreement with previously published results [3,4] but far from the value referred in [2]. The general trend is similar to that observed for iodine recoils in NaI(Tl), where an increase of the efficiency is also seen at recoil energies below ≈20 keV [9,10], and seems to disagree with theoretical estimates [11,12]. An increase of efficiency at low energy was also observed for Na recoils in NaI(Tl) and Ca and F recoils in CaF 2 scintillation crystals [10].…”

“…The quenching factor varies between 19% to 26% in the range 10 keV to 100 keV nuclear recoil energy, which agrees with previous experimental results [6,[10][11][12], as shown in Figure 4. From Figure 3(d), a scintillation efficiency of 25.2 ± 6.4% has been determined for 10 keVnr Na recoils.…”

We present preliminary results of measurements of the quenching factor for Na recoils in NaI(Tl) at room temperature, made at a dedicated neutron facility at the University of Sheffield. Measurements have been performed with a 2.45 MeV mono-energetic neutron generator in the energy range from 10 keV to 100 keV nuclear recoil energy. A BC501A liquid scintillator detector was used to tag neutrons. Cuts on pulse-shape discrimination from the BC501A liquid scintillator detector and neutron time-of-flight were performed on pulses recorded by a digitizer with a 2 ns sampling time. Measured quenching factors range from 19% to 26%, in agreement with other experiments. From pulseshape analysis, a mean time of pulses from electron and nuclear recoils are compared down to 2 keV electron equivalent energy.

In recent decades, inorganic crystals have been widely used in dark matter direct search experiments. To contribute to the understanding of the capabilities of CsI(Na) and CaF 2 (Eu) crystals, a mono-energetic neutron beam is utilized to study the properties of nuclear recoils, which are expected to be similar to signals of dark matter direct detection. The quenching factor of nuclear recoils in CsI(Na) and CaF 2 (Eu), as well as an improved discrimination factor between nuclear recoils and γ backgrounds in CsI(Na), are reported.
