Scintillation yield and time dependence from electronic and nuclear recoils in liquid neon
Abstract
We have performed measurements of scintillation light in liquid neon, observing a signal yield in our detector as high as (3.5 ± 0.4) photoelectrons/keV. We measure pulse shape discrimination efficiency between electronic and nuclear recoils in liquid neon from 50 to 300 keV nuclear recoil energy. We also measure the Leff parameter in liquid neon between 30 and 370 keV nuclear recoil energy, observing an average Leff=0.24 above 50 keV. We observe a dependence of the scintillation time distribution and signal yield on the pressure and temperature of the liquid neon.
