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 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 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 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, ...
متن کاملPreparation of Neutron-activated Xenon for Liquid Xenon Detector Calibration
We report the preparation of neutron-activated xenon for the calibration of liquid xenon (LXe) detectors. Gamma rays from the decay of xenon metastable states, produced by fast neutron activation, were detected and their activities measured in a LXe scintillation detector. Following a five-day activation of natural xenon gas with a Cf (4× 10 n/s) source, the activities of two gamma ray lines at...
