The scintillation yields and decay shapes for recoil Xe ions produced by WIMPs in liquid xenon have been examined. A quenching model based on a biexcitonic diffusion-reaction mechanism is proposed for electronic quenching. The total predicted quenching, nuclear and electronic, is compared with experimental results reported for nuclear recoils from neutrons. Model calculations give the average energy to produce a vuv photon, W ph , to be ~75 eV for 60 keV recoil Xe ions. Some aspects of ionization relating to liquid xenon WIMP detectors are also discussed.

“…Above 15 keV nuclear recoil energy, Lindhard theory is used and is consistent with experimental measurements in Si [42][43][44]. Between 0.675 and 15 keV, an empirical fit to data recently published by the DAMIC experiment [45,46] is used.…”

SuperCDMS SNOLAB will be a next-generation experiment aimed at directly detecting low-mass particles (with masses ≤ 10 GeV=c 2 ) that may constitute dark matter by using cryogenic detectors of two types (HV and iZIP) and two target materials (germanium and silicon). The experiment is being designed with an initial sensitivity to nuclear recoil cross sections ∼1 × 10 −43 cm 2 for a dark matter particle mass of * Corresponding author. tsaab@ufl.edu PHYSICAL REVIEW D 95, 082002 (2017) 2470-0010=2017=95(8)=082002 (17) 082002-1 © 2017 American Physical Society 1 GeV=c 2 , and with capacity to continue exploration to both smaller masses and better sensitivities. The phonon sensitivity of the HV detectors will be sufficient to detect nuclear recoils from sub-GeV dark matter. A detailed calibration of the detector response to low-energy recoils will be needed to optimize running conditions of the HV detectors and to interpret their data for dark matter searches. Low-activity shielding, and the depth of SNOLAB, will reduce most backgrounds, but cosmogenically produced 3 H and naturally occurring 32 Si will be present in the detectors at some level. Even if these backgrounds are 10 times higher than expected, the science reach of the HV detectors would be over 3 orders of magnitude beyond current results for a dark matter mass of 1 GeV=c 2 . The iZIP detectors are relatively insensitive to variations in detector response and backgrounds, and will provide better sensitivity for dark matter particles with masses ≳5 GeV=c 2 . The mix of detector types (HV and iZIP), and targets (germanium and silicon), planned for the experiment, as well as flexibility in how the detectors are operated, will allow us to maximize the low-mass reach, and understand the backgrounds that the experiment will encounter. Upgrades to the experiment, perhaps with a variety of ultra-low-background cryogenic detectors, will extend dark matter sensitivity down to the "neutrino floor," where coherent scatters of solar neutrinos become a limiting background.

“…To reduce the theoretical difficulties, the attention is focused on pure substances: hence only symmetric projectile/target atom combinations will be investigated. From all the avail-able measurements, known to the authors, the following are then selected: Si [3,4], Ge [5,6], and liquid Xe [7,8,9,10]. Liquid Ar will also be considered on account of its interest for dark matter searches.…”

The original Lindhard-Scharff-Schiøtt (LSS) theory and the more recent Tilinin theory for calculating the nuclear and electronic stopping powers of slow heavy ions are compared with predictions from the SRIM code by Ziegler. While little discrepancies are present for the nuclear contribution to the energy loss, large differences are found in the electronic one. When full ion recoil cascade simulations are tested against the elastic neutron scattering data available in the literature, it can be concluded that the LSS theory is the more accurate.
