“…Joshi (97) studied the feasibility of using the resonant photonuclear scattering process to further explore gamma-induced nuclear recoil calibrations. It was suggested that nuclear recoils produced by nuclear resonance fluorescence can preserve the simplicity of elastic photonuclear scattering and have enhanced interaction cross sections.…”

Detection of low-energy nuclear recoil events plays a central role in searches for weakly interacting massive particle (WIMP) dark matter interactions with atomic matter and studies of coherent neutrino scatters. Precise nuclear recoil calibration data allow the responses of these dark matter and neutrino detectors to be characterized and enable in situ evaluation of an experiment's sensitivity to anticipated signals. This article reviews the common methods for detection of nuclear recoil events and the wide variety of techniques that have been developed to calibrate detector response to nuclear recoils. We summarize the main experimental factors that are critical for accurate nuclear recoil calibrations, investigate mitigation strategies for different backgrounds and biases, and discuss how the presentation of calibration results can facilitate comparison between experiments. Lastly, we discuss the challenges for future nuclear recoil calibration efforts and the physics opportunities they may enable. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 73 is September 2023.

“…To produce nuclear recoils of known energy, several different types of experiments have been proposed; the use of monoenergetic neutron sources and tagging the scattered neutron [53,39,25], exploiting time of flight and neutron tagging with a pulsed neutron source [5], end-point measurements using a monoenergetic neutron source [41,24], use of broad spectrum neutron sources and comparison with monte carlo simulations [68], and tagged resonant photo-nuclear scatter [43]. With the exception of the proposal to use resonant photo-nuclear scatter, these experimental designs have all been employed, however successful characterization of sub-keV nuclear recoils has been limited to several results in germanium [11,42,41].…”

Liquid argon has long been used for particle detection due to its attractive drift properties, ample abundance, and reasonable density. The response of liquid argon to lowenergy O(10 2 − 10 4 eV) interactions is, however, largely unexplored. Weakly interacting massive particles such as neutrinos and hypothetical dark-matter particles (WIMPs) are predicted to coherently scatter on atomic nuclei, leaving only an isolated low-energy nuclear recoil as evidence. The response of liquid argon to low-energy nuclear recoils must be studied to determine the sensitivity of liquid argon based detectors to these unobserved interactions. Detectors sensitive to coherent neutrino-nucleus scattering may be used to monitor nuclear reactors from a distance, to detect neutrinos from supernova, and to test the predicted behavior of neutrinos. Additionally, direct detection of hypothetical weakly interacting dark matter would be a large step toward understanding the substance that accounts for nearly 27% of the universe. In this dissertation I discuss a small dual-phase (liquid-gas) argon proportional scintillation counter built to study the low-energy regime and several novel calibration and characterization techniques developed to study the response of liquid argon to low-energy O(10 2 − 10 4 eV) interactions.

“…Characterizing the response of radiation detector media to low-energy O(keV) recoiling atoms, often referred to in the literature as nuclear recoils, is necessary to accurately understand the sensitivity of radiation detectors to light weakly interacting massive particles (WIMPS) [1,2] and coherent elastic neutrino-nucleus scattering (CENNS) [3][4][5][6][7]. To produce nuclear recoils of known energy, several different types of experiments have been proposed; the use of monoenergetic neutron sources and tagging the scattered neutron [8][9][10], exploiting time of flight and neutron tagging with a pulsed neutron source [11], end-point measurements using a monoenergetic neutron source [12,13], use of broad spectrum neutron sources and comparison with monte carlo simulations [14], and tagged resonant photo-nuclear scatter [15]. With the exception of the proposal to use resonant photo-nuclear scatter, these experimental designs have all been employed, however successful characterization of sub-keV nuclear recoils has been limited to several results in germanium [7,12,16].…”

The design of a neutron source capable of producing 24 and 70 keV neutron beams with narrow energy spread is presented. The source exploits near-threshold kinematics of the $^{7}$Li(p,n)$^{7}$Be reaction while taking advantage of the interference `notches' found in the scattering cross-sections of iron. The design was implemented and characterized at the Center for Accelerator Mass Spectrometry at Lawrence Livermore National Laboratory. Alternative filters such as vanadium and manganese are also explored and the possibility of studying the response of different materials to low-energy nuclear recoils using the resultant neutron beams is discussed
