The distributed Slow Control System of the XENON100 Experiment
E. Aprile, M. Alfonsi, K. Arisaka +72
The XENON100 experiment, in operation at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, was designed to search for evidence of dark matter interactions inside a volume of…
Measurement of the Scintillation Yield of Low-Energy Electrons in Liquid Xenon
E. Aprile, R. Budnik, B. Choi +10
We have measured the energy dependence of the liquid xenon (LXe) scintillation yield of electrons with energy between 2.1 and 120.2keV, using the Compton coincidence technique. A L…
Performance of a cryogenic system prototype for the XENON1T Detector
Elena Aprile, Ran Budnik, Bin Choi +7
We have developed an efficient cryogenic system with heat exchange and associated gas purification system, as a prototype for the XENON1T experiment. The XENON1T detector will use…
Comment on "On the subtleties of searching for dark matter with liquid xenon detectors"
The XENON Collaboration, E. Aprile, M. Alfonsi +74
In a recent manuscript (arXiv:1208.5046) Peter Sorensen claims that XENON100's upper limits on spin-independent WIMP-nucleon cross sections for WIMP masses below 10 GeV "may be und…
Measurement of the Quantum Efficiency of Hamamatsu R8520 Photomultipliers at Liquid Xenon Temperature
E. Aprile, M. Beck, K. Bokeloh +12
Vacuum ultraviolet light sensitive photomultiplier tubes directly coupled to liquid xenon are being used to efficiently detect the 178 nm scintillation light in a variety of liquid…
Dark Matter Results from 225 Live Days of XENON100 Data
XENON100 Collaboration, E. Aprile, M. Alfonsi +75
We report on a search for particle dark matter with the XENON100 experiment, operated at the Laboratori Nazionali del Gran Sasso (LNGS) for 13 months during 2011 and 2012. XENON100…
