s . in s - de t ] 3 A ug 2 00 6 Gamma Ray Spectroscopy with Scintillation Light in Liquid Xenon
Scintillation light from gamma ray irradiations in liquid xenon is detected by two Hamamatsu R9288 photomultiplier tubes (PMTs) immersed in the liquid. UV light reflector material, PTFE, is used to optimize the light collection efficiency. The detector gives a high light yield of 6 photoelectron per keV (pe/keV), which allows efficient detection of the 122 keV γ-ray line from 57 Co, with a good...

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 ...
متن کاملCompton Imaging of MeV Gamma-Rays with the Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT)
The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV γ-ray sources in astrophysics. By measuring the energy deposit and the three spatial coordinates of individual γ-ray scattering points, the location of the source in the sky is inferred with Compton kinematics reconstruction. The angular resolution...
متن کاملScintillation 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...
