DESCRIPTION:Speakers: Jean-François Caron (Queen's University)\nAt the Qu
 een's University Reactor Materials Testing Laboratory (RMTL) we are develo
 ping a quasi-monoenergetic beam of intermediate-energy neutrons.  These ne
 utrons will be used to do scattering experiments on the nuclei of gas atom
 s in the NEWS-G dark matter detector to measure the so-called quenching fa
 ctor.  The quenching factor relates the energy measured from nuclear recoi
 ls (such as from a neutron or dark matter detector) to electronic recoils 
 (from normal calibration sources).  The quenching factor depends on the nu
 clear recoil energy\, so a specific and tunable neutron energy is importan
 t to get the best possible calibration for NEWS-G.  I will describe progre
 ss made in 2020\, with a new detector\, shielding\, nuclear targets\, and 
 improved positioning and alignment in the experimental room.\n\nhttps://ny
