“…Most experimental measurements of the scintillation efficiency for nuclear recoils to date were carried out with different setups but using the same method -elastic scattering of mono-energetic ∼MeV neutrons off a LXe target [61,123,124,125,126,127,128]. The scattered neutrons are detected at a fixed angle, thus allowing the energy transferred to Xe atoms to be determined kinematically.…”

Liquid noble gas detectors for low energy particle physics

2013

We review the current status of liquid noble gas radiation detectors with energy threshold in the keV range, which are of interest for direct dark matter searches, measurement of coherent neutrino scattering and other low energy particle physics experiments. Emphasis is given to the operation principles and the most important instrumentation aspects of these detectors, principally of those operated in the double-phase mode. Recent technological advances and relevant developments in photon detection and charge readout are discussed in the context of their applicability to those experiments.

“…Such factors can include uncertainties in the energy spectrum of the neutron source, efficiency losses near threshold, energy dependence of selection cuts, etc., and are typically difficult to measure precisely. Direct measurements [12,[16][17][18][19][20][21] are performed by recording fixed-angle elastic scatters of monoenergetic neutrons tagged by organic liquid scintillator detectors. The recoil energy of the Xe nucleus is then entirely fixed by kinematics and, when M Xe m n and E n m n c 2 , is approximately given by…”

New measurement of the scintillation efficiency of low-energy nuclear recoils in liquid xenon

et al. 2011

Particle detectors that use liquid xenon (LXe) as detection medium are among the leading technologies in the search for dark matter weakly interacting massive particles (WIMPs). A key enabling element has been the low-energy detection threshold for recoiling nuclei produced by the interaction of WIMPs in LXe targets. In these detectors, the nuclear recoil energy scale is based on the LXe scintillation signal and thus requires knowledge of the relative scintillation efficiency of nuclear recoils, L eff . The uncertainty in L eff at low energies is the largest systematic uncertainty in the reported results from LXe WIMP searches at low masses. In the context of the XENON Dark Matter project, a new LXe scintillation detector has been designed and built specifically for the measurement of L eff at low energies, with an emphasis on maximizing the scintillation light detection efficiency to obtain the lowest possible energy threshold. We report new measurements of L eff at low energies performed with this detector. Our results suggest a L eff which slowly decreases with decreasing energy, from 0.144 ± 0.009 at 15 keV down to 0.088 +0.014 −0.015 at 3 keV.
