Scintillation time dependence and pulse shape discrimination in liquid argon
Scintillation time dependence and pulse shape discrimination in liquid argon
Using a single-phase liquid argon detector with a signal yield of 4.85 photoelectrons per keV of electronic-equivalent recoil energy (keVee), we measure the scintillation time dependence of both electronic and nuclear recoils in liquid argon down to 5 keVee. We develop two methods of pulse shape discrimination to distinguish between …
