“…These values are also consistent with those estimated from the measured refractive index [159,157]. For liquid argon, an experimental value of L s = 66 cm has been reported [156], while theoretical calculations predict 90 cm [158].…”

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.

“…The best fit to the data for the scattering length at 128 nm, is 46±11 cm, which is in agreement with 55 ± 5 cm obtained in reference [21] where the Rayleigh scattering length was extrapolated from measurements at higher wavelengths. However, it is in tension with a value of 66 ± 3 cm, which was directly measured at 128 nm [22], and a value of 90 cm that is obtained from theoretical considerations [20].…”

A: A Geant4-based Monte Carlo package named G4DS has been developed to simulate the response of DarkSide-50, an experiment operating since 2013 at LNGS, designed to detect WIMP interactions in liquid argon. In the process of WIMP searches, DarkSide-50 has achieved two fundamental milestones: the rejection of electron recoil background with a power of ∼10 7 , using the pulse shape discrimination technique, and the measurement of the residual 39 Ar contamination in underground argon, ∼3 orders of magnitude lower with respect to atmospheric argon. These results rely on the accurate simulation of the detector response to the liquid argon scintillation, its ionization, and electron-ion recombination processes. This work provides a complete overview of the DarkSide Monte Carlo and of its performance, with a particular focus on PARIS, the custommade liquid argon response model.

“…However, several authors have reported a value of about 30 cm to 40 cm for the total attenuation length (see [8], [9] and references therein). Using λ tot =35 cm, which sets the constraint 1/λ tot =1/λ scat +1/λ abs , and assuming that λ tot =λ scat (i.e.…”

-The design and performance of a 1.2 liter liquid xenon chamber equipped with 7 two-inch photomultiplier tubes, with the purpose of studying the scintillation response of xenon to γ-rays and neutrons, is described. Measurements with γ-rays indicate a high VUV light collection efficiency resulting in ~5.5 photoelectrons per 1 keV of deposited energy. The energy resolution (FWHM) is 18% and 22%, for 122 keV and 511 keV γ-rays, respectively. An algorithm for the reconstruction of the scintillation coordinates in (x,y) plane was developed and tested. The position resolution is estimated to be σ=6.9 mm for 122 keV γ-rays.
