Analysis of the XENON100 dark matter search data
Aprile, E.; Alfonsi, M.; Arisaka, K.; Arneodo, F.; Balan, C.; Baudis, L.; Behrens, A.; Beltrame, P.; Bokeloh, K.; Brown, E.; Bruno, G.; Budnik, R.The XENON100 experiment, situated in the Laboratori Nazionali del Gran Sasso, aims at the direct detection of dark matter in the form of weakly interacting massive particles (WIMPs), based on their interactions with xenon nuclei in an ultra low background dual-phase time projection chamber. This paper describes the general methods developed for the analysis of the XENON100 data. These methods have been used in ...

Sorensen, P.; Manzur, A.; Dahl, C. E.; Angle, J.; Aprile, E.; Arneodo, F.; Baudis, L.; Bernstein, A.; Bolozdynya, A.; Coelho, L. C. C.; DeViveiros, L.http://www.sciencedirect.com/science/article/B6TJM-4VBDGYK-3/2/955ce6ee62330f437f352d46bbc8f500
XENON
Aprile, E.; Giboni, K.-L.; Monzani, M. E.; Plante, G.; Yamashita, M.; Gaitskell, R. J.; Fiorucci, S.; Sorensen, P.; DeViveiros, L.; Bernstein, A.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 1 ton of LXe distributed in ten identical modules, the proposed XENON1T experiment will achieve a sensitivity more than a factor of thousand beyond current limits.The detectors are time projection chambers operated in dual (liquid/gas) p...
3D Position Sensitive XeTPC for Dark Matter Search
Angle, J.; Aprile, E.; Arneodo, F.; Baudis, L.; Bernstein, A.; Bolozdynya, A.; Coelho, L.; Dahl, E.; DeViveiros, L.; Ferella, A.; Fernandes, L.The technique to realize 3D position sensitivity in a two-phase xenon time projection chamber (XeTPC) is described. Results from a prototype detector (XENON3) are presented. ; http://www.sciencedirect.com/science/article/B6TVD-4R68DXJ-13/1/c7a25befd9bec275706d42709c6eb3c6
Performance of a large area avalanche photodiode in a liquid xenon ionization a...
Ni, K.; Aprile, E.; Day, D.; Giboni, K. L.; Lopes, J. A. M.; Majewski, P.; Yamashita, M.Scintillation light produced in liquid xenon (LXe) by alpha particles, electrons and gamma-rays was detected with a large area avalanche photodiode (LAAPD) immersed in the liquid. The alpha scintillation yield was measured as a function of applied electric field. We estimate the quantum efficiency of the LAAPD to be 45%. The best energy resolution from the light measurement at zero electric field is 7.5%([sigma...
