Precision measurement of Compton scattering in silicon with a skipper CCD for dark matter detection

Experiments aiming to directly detect dark matter through particle recoils can achieve energy thresholds of \mathcal{O}(1\,\mathrm{eV}). In this regime, ionization signals from small-angle Compton scatters of environmental \gamma-rays constitute a significant background. Monte Carlo simulations used to build background models have not been experimentally validated at these low energies. We... Show more
