“…As the coupling becomes stronger for molecules with higher atomic number, the decay time is significantly shorter for LXe (∼27 ns). Conversely, the triplet lifetime is even longer in LNe (15 µs [84]) and reaches ∼13 seconds in LHe [85].…”

Liquid noble gas detectors for low energy particle physics

2013

View full text Add to dashboard Cite

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.

“…It is well known that noble liquid scintillators have reduced scintillation yield for low-energy nuclear recoils compared to electronic recoils [9,10,11,12,13,14]. Only a fraction of the energy loss results in ionization and atomic excitation.…”

“…In the interpretation of an experimental result, the scintillation efficiency is crucial to the determination of WIMP mass and WIMP-nucleon cross section. The nuclear recoil scintillation efficiencies for liquid xenon, argon, and neon have been measured [9,10,11,12,13,14] using neutron sources. The detector is usually calibrated with well-known γ-rays, such as 122 keV and 133 keV lines from a 57 Co source.…”

Scintillation efficiency of low-energy nuclear recoils in noble liquids plays a crucial role in interpreting results from some direct searches for Weakly Interacting Massive Particle (WIMP) dark matter. However, the cause of a reduced scintillation efficiency relative to electronic recoils in noble liquids remains unclear at the moment. We attribute such a reduction of scintillation efficiency to two major mechanisms: 1) energy loss and 2) scintillation quenching. The former is commonly described by Lindhard's theory and the latter by Birk's saturation law. We propose to combine these two to explain the observed reduction of scintillation yield for nuclear recoils in noble liquids. Birk's constants kB for argon, neon and xenon determined from experimental data are used to predict noble liquid scintillator's response to low-energy nuclear recoils and low-energy electrons. We find that energy loss due to nuclear stopping power that contributes little to ionization and excitation is the dominant reduction mechanism in scintillation efficiency for nuclear recoils, but that significant additional quenching results from the nonlinear response of scintillation to the ionization density.

“…Future large-scale lowenergy threshold underground detectors, such as the CLEAN detector [12], will be sensitive to all active neutrino species in a supernova burst, and will be flavor blind [13]. Hence, detecting supernova neutrinos in such a detector may provide a total flux and spectrum of neutrinos from supernova if the cross section of CENNS can be independently and accurately measured.…”

A method for measuring coherent elastic neutrino-nucleus scattering at a far off-axis high-energy neutrino beam target

et al. 2014

We present a new experimental method for measuring the process of Coherent Elastic Neutrino Nucleus Scattering (CENNS). This method uses a detector situated transverse to a high energy neutrino beam production target. This detector would be sensitive to the low energy neutrinos arising from pion decays-at-rest in the target. We discuss the physics motivation for making this measurement and outline the predicted backgrounds and sensitivities using this approach. We report a measurement of neutron backgrounds as found in an off-axis surface location of the Fermilab Booster Neutrino Beam (BNB) target. The results indicate that the Fermilab BNB target is a favorable location for a CENNS experiment.
