Abstract:
The New Experiments With Spheres-Gas (NEWS-G) collaboration
intends to achieve sub-GeV/c 2 Weakly Interacting
Massive Particles (WIMPs) detection using Spherical Proportional Counters (SPCs). SPCs are gaseous detectors relying on ionisation
with a single ionization electron energy threshold. The latest generation of SPC for direct dark matter searches has been installed
at SNOLAB in Canada in 2021. This article details the different processes involved in the fabrication of the NEWS-G experiment. Also
outlined in this paper are the mitigation strategies, measurements of radioactivity of the different components, and estimations of
induced background event rates that were used to quantify and address detector backgrounds.
