A study of the NaI(Tl) detector response to low energy nuclear recoils and a measurement of the quenching factor in NaI(Tl)

Understand

We analyzed the response of NaI(Tl) to low energy nuclear recoils in the experiment that is reported on here.

• Such detectors have been used recently to search for evidence of dark matter in the form of weakly interacting massive particles (WIMPs).
• Understanding the response of these detectors to low energy nuclear recoils is crucial in these searches.
• We have measured nuclear recoils and associated quenching factors (QF) for sodium recoils in the energy range of 8 keV - 48 keV.
