“…In this way, the model is compatible with the data with a p-value of 0.79 as shown in figure 15, and the best fit parameters are k B = (5.2±0.6)×10 −4 MeV −1 g cm −2 and k * B = (-2.0±0.7)×10 −7 MeV −2 g 2 cm −4 . This result is in agreement with the best fit of the modified Mei model to DarkSide-50 data which yields a value of k B = (4.66 +0.86 −0.94 )×10 −4 MeV −1 g cm −2 [21].…”

A liquid argon time projection chamber, constructed for the Argon Response to Ionization and Scintillation (ARIS) experiment, has been exposed to the highly collimated and quasi-monoenergetic LICORNE neutron beam at the Institute de Physique Nuclaire Orsay in order to study the scintillation response to nuclear and electronic recoils. An array of liquid scintillator detectors, arranged around the apparatus, tag scattered neutrons and select nuclear recoil energies in the [7, 120] keV energy range. The relative scintillation efficiency of nuclear recoils was measured to high precision at null field, and the ion-electron recombination probability was extracted for a range of applied electric fields. Single-scattered Compton electrons, produced by gammas emitted from the de-excitation of 7 Li * in coincidence with the beam pulse, along with calibration gamma sources, are used to extract the recombination probability as a function of energy and electron drift field. The ARIS results have been compared with three recombination probability parameterizations (Thomas-Imel, Doke-Birks, and PARIS), allowing for the definition of a fully comprehensive model of the liquid argon response to nuclear and electronic recoils down to a few keV range. The constraints provided by ARIS to the liquid argon response at low energy allow the reduction of systematics affecting the sensitivity of dark matter search experiments based on liquid argon.

Proportional electroluminescence (EL) in noble gases has long been used in two-phase detectors for dark matter search, to record ionization signals induced by particle scattering in the noble-gas liquid (S2 signals). Until recently, it was believed that proportional electroluminescence was fully due to VUV emission of noble gas excimers produced in atomic collisions with excited atoms, the latter being in turn produced by drifting electrons. In this work we consider an additional mechanism of proportional electroluminescence, namely that of bremsstrahlung of drifting electrons scattered on neutral atoms (so-called neutral bremsstrahlung); it is systemically studied here both theoretically and experimentally. In particular, the absolute EL yield has for the first time been measured in pure gaseous argon in the two-phase mode, using a dedicated two-phase detector with EL gap optically read out by cryogenic PMTs and SiPMs. We show that the neutral bremsstrahlung effect can explain two intriguing observations in EL radiation: that of the substantial contribution of the non-VUV spectral component, extending from the UV to NIR, and that of the photon emission at lower electric fields, below the Ar excitation threshold. Possible applications of neutral bremsstrahlung effect in two-phase dark matter detectors are discussed.

“…The 83m Kr and 22 Na results have been shown in Table 1 and Table 2. The PARIS [29] model provides a good description of electric recoils (ERs) in liquid argon. The measured electric field induced quenching of light yield for ERs is 8.4% for 83m Kr and 21.4% for 22 Na at 200V/cm.…”

83m Kr and 22 Na have been used in calibrating a liquid argon (LAr) detector. 83m Kr atoms are produced through the decay of 83 Rb and introduced into the LAr detector through the circulating purification system. The light yield reaches 7.26±0.02 photonelectrons/keV for 41.5keV from 83m Kr and 7.66±0.01 photonelectrons/keV for the 511keV from 22 Na, as a comparison. The light yield varies with the drift electric field from 50 to 200V/cm have been also reported. After stopping fill, the decay rate of 83m Kr with a fitted half-life of 1.83±0.11 h, which is consistent with the reported value of 1.83±0.02 h.
