Observation and applications of single-electron charge signals in the XENON100 experiment
E. Aprile, M. Alfonsi, K. Arisaka +77
The XENON100 dark matter experiment uses liquid xenon in a time projection chamber (TPC) to measure xenon nuclear recoils resulting from the scattering of dark matter Weakly Intera…
The neutron background of the XENON100 dark matter experiment
E. Aprile, M. Alfonsi, K. Arisaka +74
The XENON100 experiment, installed underground at the Laboratori Nazionali del Gran Sasso (LNGS), aims to directly detect dark matter in the form of Weakly Interacting Massive Part…
An atom trap trace analysis system for measuring krypton contamination in xenon dark matter detectors
Elena Aprile, Taehyun Yoon, Andre Loose +2
We have developed an atom trap trace analysis (ATTA) system to measure Kr in Xe at the part per trillion (ppt) level, a prerequisite for the sensitivity achievable with liquid xeno…
Response of the XENON100 Dark Matter Detector to Nuclear Recoils
The XENON100 Collaboration, E. Aprile, M. Alfonsi +80
Results from the nuclear recoil calibration of the XENON100 dark matter detector installed underground at the Laboratori Nazionali del Gran Sasso (LNGS), Italy are presented. Data…
Limits on spin-dependent WIMP-nucleon cross sections from 225 live days of XENON100 data
XENON100 collaboration, E. Aprile, M. Alfonsi +75
We present new experimental constraints on the elastic, spin-dependent WIMP-nucleon cross section using recent data from the XENON100 experiment, operated in the Laboratori Naziona…
