Performance and Fundamental Processes at Low Energy in a Two-Phase Liquid Xenon Dark Matter Detector
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-sensi...
متن کاملPrototyping Liquid Argon Dark Matter Detector
The aim of the project is to build a small ion chamber serving as a prototype of a much larger dark matter detector to be built in the future. This is a brand-new project at Fermilab; my task would be to come up with the prototype ion chamber and a first set of measurements. To start with, the small chamber is going to be filled with Argon extracted from the air, i.e. predominantly 40Ar and tra...
متن کاملArDM, a 1t liquid argon detector for dark matter searches
Weak Interacting Massive Particles (WIMPs) are prime candidates for the dark matter in the universe. The ArDM experiment consists of a 1t liquid argon detector to search for WIMPs interacting elastically with argon nuclei. Both scintillation light and ionization charge from nuclear recoils are measured. The 128 nm light is reflected and shifted into the visible range by wavelength shifting foil...
متن کاملSUSY dark matter ∗ –
A short tour of supersymmetric dark matter and its connection to collider physics. 1. Quest for the dark matter Recently the existence of dark matter has been confirmed through the CMB measurements [1]. Because the baryon density of the universe Ωb is only 1/6 of the matter density of the universe Ωmh = 0.27 ± 0.04, the dark matter should be explained by the physics beyond standard model(SM). T...
متن کاملWARP liquid argon detector for dark matter survey
The WARP programme is a graded programme intended to search for cold Dark Matter in the form of WIMP’s. These particles may produce via weak interactions nuclear recoils in the energy range 10 − 100 keV . A cryogenic noble liquid like argon, already used in the realization of very large detector, permits the simultaneous detection of both ionisation and scintillation induced by an interaction, ...
