Monte-Carlo simulations of positron emission tomography based on liquid xenon detectors
… Positron Emission Tomography imaging using liquid xenon (LXe) gamma ray detectors had been examined. Monte-Carlo simulations using GEANT4 were performed and the results were used to study the expected performance of a small animal PET scanner in comparison with a simulated conventional small …

XENON100 Dark Matter Search: Scintillation Response of Liquid Xenon to Electronic Recoils
… efforts have been made to search for WIMPs. The XENON100 dark matter experiment is currently the most sensitive experiment in the global race for the first direct detection of WIMP dark matter. XENON100 is a dual-phase (liquid-gas) time projection chamber containing a total of 161 kg of liquid …

In-situ laser tagging of barium ions in liquid xenon for the EXO experiment
The goal of the Enriched Xenon Observatory (EXO) collaboration is to measure the half-life of neutrino-less double beta decay using a ton size liquid 136Xe detector with zero back-ground. Zero background detection can only be achieved if the daughter nucleus, 136Ba, can be tagged. The EXO …

The Light Response of the XENON100 Time Projection Chamber and the Measurements of the Optical Parameters with the Xenon Scintillation Light
The XENON program is a phased project using liquid xenon as a sensitive detector medium in search for weakly interacting massive particles (WIMPs). These particles are the leading candidates to explain the non-baryonic, cold dark matter in our Universe. XENON100, the successor experiment of …

The XENON100 Dark Matter Experiment: Design, Construction, Calibration and 2010 Search Results with Improved Measurement of the Scintillation Response of Liquid Xenon to Low-Energy Nuclear Recoils
… is expected to scatter off nuclei. In 2007, the XENON10 experiment took the lead over the most sensitive direct detection dark matter search in operation, the CDMS II experiment, by probing spin-independent WIMP-nucleon interaction cross sections down to σχN ~ 5 × 10-44 cm2 at 30GeV/c2. Liquefied …

Mobility and fluorescence of barium ions in xenon gas for the EXO experiment
The Enriched Xenon Observatory (EXO) is an experiment which aims to observe the neutrinoless double beta decay of 136Xe. The measurement of this decay would give information about the absolute neutrino mass and whether or not the neutrino is its own antiparticle. Since this is a very rare decay, …

Novel Electromagnetic Properties of Elementary Particles
… because they have less in-medium effects than liquid Xenon for example. Monopoles of TeV scale masses can be produced by Cosmic Ray - Interstellar Medium collisions. These monopoles would impact the well measured 10−6 Gauss galactic magnetic field or it's production mechanism allowing us to …

The search for dark matter in xenon: Innovative calibration strategies and novel search channels
<p>The direct detection dark matter experiment XENON1T became operational in early 2016, heralding the era of tonne-scale dark matter detectors. Direct detection experiments typically search for elastic scatters of dark matter particles off target nuclei. XENON1T's larger xenon target provides the …

Search for neutrinoless double-beta decay and 42Ar in enriched xenon using the EXO-200 dataset
… on the neutrino mass scale. The Enriched Xenon Observatory experiment (EXO-200) operated an extremely radio-pure tracking calorimeter filled with liquid xenon enriched in the candidate isotope 136Xe and installed underground in New Mexico, USA. The author presents a search for 0νββ with …

Transport modeling of simple fluids and nano-colloids : thermal conduction mechanisms and coarse projection
… clusters which interact strongly with host liquid xenon, a significant thermal conductivity enhancement is obtained as a result of self correlation in the potential energy flux. The effect saturates at higher volume fractions due to the cross-mode correlation between the potential and the …

An atom trap trace analysis (ATTA) system for measuring ultra-low contamination by krypton in xenon dark matter detectors
The XENON dark matter experiment aims to detect hypothetical weakly interacting massive particles (WIMPs) scattering off nuclei within its liquid xenon (LXe) target. The trace 85Kr in the xenon target undergoes beta-decay with a 687 keV end point and 10.8 year halflife, which contributes background …
