Description
The NEWS-G experiment, located at the Sudbury Neutrino Observatory (SNO) in Canada, is searching for Weakly Interacting Massive Particles (WIMPs) in the sub-GeV mass range. This direct dark matter detection experiment uses Spherical Proportional Counters (SPCs) as detectors, which measure nuclear recoils in noble gases. Since nuclear recoils are quenched compared to electronic recoils, precise measurements of the quenching factor (QF) are essential for accurately calibrating the detector for nuclear recoil events. Therefore, it plays a key role in determining sensitivity of the detector towards dark matter detection.
This work outlines the ongoing efforts of the NEWS-G group to measure the quenching factor (QF) for various gas mixtures, pressures, and neutron energies. The measurements at the tandem accelerator at the University of Montreal will also be briefed.
