Scintillation of Xenon doped Liquid Argon in the BACON Detector
The BACON liquid argon (LAr) scintillation detector prototype will be used to measure 1 2 intensity, promptness , and decay behavior for pure LAr and xenon (Xe) doped LAr mixtures. 3 The goal is to aid in planning, cost reduction, and improved detection for the Deep Underground Neutrino Experiment (DUNE) [6]. The scintillation of LAr is in the vacuum ultra-violet (VUV), requiring detectors to u...
متن کاملPerformance of a Large Area Avalanche Photodiode in a Liquid Xenon Ionization and Scintillation Chamber
Scintillation light produced in liquid xenon (LXe) by alpha particles, electrons and gamma-rays was detected with a large area avalanche photodiode (LAAPD) immersed in the liquid. The alpha scintillation yield was measured as a function of applied electric field. We estimate the quantum efficiency of the LAAPD to be 45%. The best energy resolution from the light measurement at zero electric fie...
متن کاملPreparation of Neutron-activated Xenon for Liquid Xenon Detector Calibration
We report the preparation of neutron-activated xenon for the calibration of liquid xenon (LXe) detectors. Gamma rays from the decay of xenon metastable states, produced by fast neutron activation, were detected and their activities measured in a LXe scintillation detector. Following a five-day activation of natural xenon gas with a Cf (4× 10 n/s) source, the activities of two gamma ray lines at...
متن کاملDetection of Liquid Xenon Scintillation Light with a Silicon Photomultiplier
We have studied the feasibility of a silicon photomultiplier (SiPM) to detect liquid xenon (LXe) scintillation light. The SiPM was operated inside a small volume of pure LXe, at -95C, irradiated with an internal Am α source. The gain of the SiPM at this temperature was estimated to be 1.8 × 10 with bias voltage at 52 V. Based on the geometry of the setup, the quantum efficiency of the SiPM was ...
