| Abstract | The detection of scintillation light from liquid argon is an experimental technique key to a number of current and future nuclear/particle physics experiments, such as neutrino physics, neutrinoless double beta decay and dark matter searches. Although the idea of adding small quantities of xenon (doping) to enhance the light yield has attracted considerable interest, this technique has never been demonstrated at the necessary scale. Here we report on xenon doping in a 100~l crogenic vessel. We observed an increase in light yield by a factor of 1.81$\pm$0.04 at a dopant concentration of 10~ppm, consistent with a Geant4 prediction of 1.83$\pm$0.02. We determine a lower limit on the attenuation length of $3$~m at a concentration of 10~ppm |
