Description
The NEWS-G experiment searches for low-mass dark matter using spherical proportional counters (SPCs). An SPC is a sphere filled with gas, with a high-voltage anode at its centre producing a radial electric field, sensitive to ionizing particles within the detector. The largest NEWS-G detector is a sphere of 135cm of diameter currently taking data at SNOLAB. This talk will explain how an SPC works, how NEWS-G discriminates background signal events and what work is being done at Queen’s University to contribute to the search for dark matter, and more!
