New Technique for the Measurement of the Scintillation Efficiency of Nuclear Recoils
We present a new technique developed for the measurement of the scintillation efficiency of nuclear recoils in solid scintillators. Using this technique we measured the quenching of the scintillation efficiency for the various recoiling nuclei in CaWO4 crystals which are used in direct Dark Matter searches.
متن کاملMEASUREMENT OF THE SCINTILLATION EFFICIENCY OF Na RECOILS IN NaI(Tl) DOWN TO 10 keV NUCLEAR RECOIL ENERGY RELEVANT TO DARK MATTER SEARCHES
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...
متن کاملMeasurements of Scintillation Efficiency and Pulse-Shape for Low Energy Recoils in Liquid Xenon
Results of observations of low energy nuclear and electron recoil events in liquid xenon scintillator detectors are given. The relative scintillation efficiency for nuclear recoils is 0.22 ± 0.01 in the recoil energy range 40 keV 70 keV. Under the assumption of a single dominant decay component to the scintillation pulse-shape the log-normal mean parameter T0 of the maximum likelihood estimator...
متن کاملScintillation efficiency of liquid xenon for nuclear recoils with the energy down to 5 keV
The scintillation efficiency of liquid xenon for nuclear recoils has been measured to be nearly constant in the recoil energy range from 140 keV down to 5 keV. The average ratio of the efficiency for recoils to that for gamma-rays is found to be 0.19±0.02. PACS codes: 29.40.Mc, 78.70.-g, 78.60.-b, 95.35.+d
متن کاملScintillation efficiency of nuclear recoils in a CaF2(Eu) crystal for dark matter search
The scintillation efficiency (quenching factor) of fluorine and calcium nuclei recoiling in a CaF2(Eu) crystal was measured in an energy region relevant to dark matter searches. The recoiling nuclei were obtained via the 19F(n,n’) and 40Ca(n,n’) reactions, where the neutron beam was provided via the d(d,n)3He reaction. The quenching factor of F and Ca nuclei in the CaF2(Eu) crystal was found to...
