    Light/charge response in noble elements
    Presentation

    Dual-phase noble gas Time Projection Chambers (TPCs) suffer from spurious electron background events at the lowest detectable energy region. This background is reported in liquid xenon TPCs and some of the causes are discussed in the literature. Understanding its origin is of paramount importance as this background sets the analysis threshold and affects the most sensitive part of the region...

  2. 44. Experimental study of Ar ion drift and feedback from gas to liquid phase

    Light/charge response in noble elements
    Presentation

    A large positive volume charge can distort the drift field and quench the charge signal in a massive argon time projection chamber, thus the study of the dynamics of the positive ions created by particle interactions in liquid argon is essential for the characterization of the new generation of experiments planned for the dark matter direct search and neutrino physics. We have constructed a 1...

    Light/charge response in noble elements
    Presentation

    Abstract.
    Dual-phase noble liquid time-projection chambers have a long application history in searches for rare low-energy events like interactions with dark matter particles. Because of scalability and existing support infrastructure, they are expected to serve in large future projects. Our analysis of data and models for electrons and ions extraction from the liquid into the gas phase and...

    Light/charge response in noble elements
    Presentation

    It has been known that noble elements, when excited by ionizing radiation, emit light not only in the vacuum ultraviolet (VUV) region but also at longer wavelengths, up to the near-infrared (NIR). Many questions remain on the exact nature of this scintillation both in terms of its atomic/molecular origin as well as its full characterization as regards the light yield, spectral and time...

  5. 2. Lindhard integral equation with binding energy apply to light and charge yields nuclear recoils in noble liquid detectors

    Light/charge response in noble elements
    Presentation

    We present a model for the ionization efficiency, or quenching factor, for low energy nuclear recoils based on a solution to Lindhard's integral equation with binding energy and apply it to the calculation of the relative scintillation efficiency and charge yield for noble liquid detectors. The quenching model incorporates a constant average binding energy together with an electronic stopping...

  6. 12. Calibrating the scintillation and ionization responses of xenon recoils for high-energy dark matter searches

    Detector techniques (HV, purification, cryogenics, calibration etc.)
    Presentation

    Liquid xenon-based direct detection dark matter experiments have recently expanded their searches to include high-energy nuclear recoil events as motivated by effective field theory dark matter and inelastic dark matter interaction models, but few xenon recoil calibrations above 100 keV are currently available. In this presentation, we show our measurements of the scintillation and ionization...

    Light/charge response in noble elements
    Presentation

    To increase sensitivity of liquid xenon (LXe) experiments to light WIMPs, the response of the LXe medium to sub-keV nuclear recoils must be characterized. We study the feasibility for an ultra-low energy nuclear-recoil yield measurement in LXe using neutron capture. The measurement strategy uses the recoil energies imparted to xenon nuclei during the de-excitation process following neutron...

    Light/charge response in noble elements
    Either Presentation or Poster

    Bubble chambers using liquid xenon (and liquid argon) have been operated (resp. planned) by the Scintillating Bubble Chamber (SBC) collaboration for GeV-scale dark matter searches and CEvNS from reactors. This requires a robust calibration program of the nucleation efficiency of low-energy nuclear recoils in these target media. Such experiments were performed with a liquid xenon test chamber,...
