R&D Results and Status of the XENON Dark Matter Experiment
The XENON experiment aims at the direct detection of dark matter in the form of WIMPs (Weakly Interacting Massive Particles) via their elastic scattering off Xenon nuclei. With a fiducial mass of 1000 kg of liquid xenon, a sufficiently low threshold of 16 keV recoil energy and an unrejected background rate of 10 events per year, XENON would be sensitive to a WIMP-nucleon interaction cross secti...
متن کاملThe XENON Dark Matter Search Experiment
The XENON experiment aims at the direct detection of dark matter in the form of WIMPs (Weakly Interacting Massive Particles) via their elastic scattering off Xe nuclei. A fiducial mass of 1000 kg, distributed in ten independent liquid xenon time projection chambers(LXeTPCs) will be used to probe the lowest interaction cross section predicted by SUSY models. The TPCs are operated in dual (liquid...
متن کاملDevelopment of a liquid - xenon photon detector – – towards the search for a muon rare decay mode at Paul Scherrer Institute q
We are developing a new type of photon detector in preparation of an experiment to search for muons decaying into positrons and gamma rays. In the experiment, the photon detector will utilize liquid xenon (Xe) as the scintillation material because of its fast response, large light yield, and high density. The scintillation light emitted in liquid Xe will be observed directly by positioning phot...
متن کاملMeasuring Electron Response in NaI(Tl) using Compton Coincidence Technique
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...
متن کاملMeasurements of Scintillation Efficiency and Pulse-Shape for Low Energy Recoils in Liquid Xenon
Results of observations of low energy nuclear and electron recoil events in liquid xenon scintillator detectors are given. The relative scintillation efficiency for nuclear recoils is 0.22 ± 0.01 in the recoil energy range 40 keV 70 keV. Under the assumption of a single dominant decay component to the scintillation pulse-shape the log-normal mean parameter T0 of the maximum likelihood estimator...
