Development of spherical proportional counter for light WIMP search within NEWS-G collaboration

Popis výsledku v původním jazyce

The Spherical gaseous detector (or Spherical Proportional Counter, SPC) has a broad range of applications. In this work, we will focus on the light WIMP Dark Matter particle search, that is, below a few GeV. The NEWS-G collaboration operates a 60 cm diameter detector at Modane underground laboratory (LSM). Running the detector at 3 bars of Neon gas, some competitive limits have been set down to 0.5 GeV WIMP mass thanks to an energy threshold of around 100 eV. To reach better performances, the next generation of SPC (140 cm), NEWS-G_SNO, is under construction. We will focus here on the fabrication method, the different low energy calibration methods using(37)Ar, neutron and UV laser, on the cleaning methods to remove the surface contamination and mitigation of(210)Pb bulk contamination.
