Some Problems of Measurements of Ionization Yields for Nuclear Recoils in Liquid Argon Using Neutron Scattering in a Two-Phase Detector
Abstract
Measurement of the ionization yields for nuclear recoils is related to the energy calibration of dark matter and low-energy neutrino detectors. In this study, some results of the previous measurements of the ionization yields for nuclear recoils in liquid argon using the neutron scattering technique in the two-phase detector are discussed. The methods to increase light collection of scintillation ( S 1) and ionization ( S 2) signals in the two-phase detector using SiPM matrices and THGEM electrodes with increased optical transparency are proposed. These steps are necessary to implement the neutron double-scattering technique, which will provide measurement of the ionization yield of recoiling nuclei in the unexplored energy range.
