The scintillation efficiency of electron recoils in liquid xenon (LXe) is not well measured at low energies. The Compton coincidence technique (CCT) is set up using a NaI(Tl) detector and HPGe detector to measure the energy dependence of the light yield in the NaI(Tl) detector from which we can extract the scintillation effieciency. This technique allows for the detection of low energy electron...

The MicroBooNE detector, to be located on axis in the Booster Neutrino Beamline (BNB) at the Fermi National Accelerator Laboratory (Fermilab), consists of two main components: a large liquid argon time projection chamber (LArTPC), and a light collection system. Thirty 8inch diameter Hamamatsu R5912-02mod cryogenic photomultiplier tubes (PMTs) will detect the scintillation light generated in the...

The Yale-Weizmann collaboration aims to develop a lowradioactivity (low-background) cryogenic noble liquid detector for Dark-Matter (DM) search in measurements to be performed deep underground as for example carried out by the XENON collaboration. A major issue is the background induced by natural radioactivity of present-detector components including the Photo Multiplier Tubes (PMT) made from ...

A unique, new stand-alone acoustic inertial confinement nuclear fusion test device was successfully tested. Experiments using four different liquid types were conducted in which bubbles were self-nucleated without the use of external neutrons. Four independent detection systems were used (i.e., a neutron track plastic detector to provide unambiguous visible records for fast neutrons, a detector...

A ZnS(Ag) detector was successfully used in the direct detection of alpha particles from aqueous solutions and the results were compared to the passivated ion implanted planar silicon (PIPS) continuous air monitor (CAM) detector. The ZnS(Ag) detector is recommended for on-line detection of gross alpha radioactivity from highlevel liquid waste process streams; however, the detector suffers from ...

MACRO was a large multipurpose underground detector located in the Hall B of the Laboratori Nazionali del Gran Sasso. The detector, which took data until December 2000, was arranged in a modular structure of six “supermodules” with global dimensions of 76.5 × 12 × 9.3m and a total acceptance of ∼ 10, 000 msr to an isotropic flux of particles. It was made by several layers of liquid scintillatio...

The Dark Matter part of the universe presumably consists of WIMPs (Weakly Interacting Massive Particles). The ArDM project aims at measuring signals induced by WIMPs in a liquid argon detector. A 1-ton prototype is currently developed with the goal of demonstrating the feasibility of such a direct detection experiment with large target mass. The technical design of the detector aims at independ...

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...

Background: : Due to the difficulties of locally obtaining ZnS(Ag), preliminary investigation of the radioluminescence characterization of Zinc oxide (ZnO) for alpha particle detection was performed. Materials and Methods: The scintillation properties of ZnO films were tested using alpha sources                &nbsp...

A light-yield calibration of an NE 213A organic liquid scintillator detector has been performed using both monoenergetic and polyenergetic gamma-ray sources. Scintillation light was detected in a photomultiplier tube, the corresponding pulses were subjected to waveform digitization on event-by-event basis. The resulting Compton edges have analyzed GEANT4 simulation which models interactions ion...
