Performance and Fundamental Processes at Low Energy in a Two-Phase Liquid Xenon Dark Matter Detector
نویسنده
چکیده
We extend the study of the performance of a prototype two-phase liquid xenon WIMP dark matter detector to energies below 20 keV. We demonstrate a new method for obtaining the best estimate of the energy from events, show that fluctuations in recombination limit discrimination for most energies, and reveal a surprising improvement in discrimination below 20 keV, which is crucial for a high-sensitivity dark matter search.

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 کاملA ug 2 00 0 Low Energy Solar Neutrino Detection by using Liquid Xenon
Possibility to use ultra pure liquid Xenon as a low energy solar neutrino detector by means of ν+e scatterings is evaluated. A possible detector with 10 tons of fiducial volume will give ∼14 events for pp-neutrinos and ∼6 events for 7 Be neutrinos with the energy threshold at 50 keV. The detector can be built with known and established technologies. High density of the liquid-Xe would provide s...
متن کاملThe ZEPLIN-III dark matter detector: performance study using an end-to-end simulation tool
We present results from a GEANT4-based Monte Carlo tool for end-to-end simulations of the ZEPLIN-III dark matter experiment. ZEPLIN-III is a two-phase detector which measures both the scintillation light and the ionisation charge generated in liquid xenon by interacting particles and radiation. The software models the instrument response to radioactive backgrounds and calibration sources, inclu...
