The XENON1T Dark Matter Direct Detection Experiment — •Serena Fattori — Johannes Gutenberg-Universität, Mainz, Germany
The worldwide competition for dark matter search, in the form of Weakly Interacting Massive Particles (WIMPs), has been greatly accelerated by the remarkable progress of liquid xenon time projection chambers (LXeTPCs). XENON100, located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, is the most sensitive realization to date, currently leading Dark Matter searches by far with a limit for the spin-independent WIMP-nucleon cross section of 2×10−45 cm2.
To fully explore the favoured parameter space for WIMP dark matter interaction with ordinary matter, towards a first robust and statistically significant discovery, the next phase of the XENON program is a detector at the ton scale - XENON1T. The XENON1T detector is based on ∼ 3 ton of LXe, ∼ 1 ton fiducial, viewed by 3 inch low radioactivity photomultiplier tubes. Housed in a water Cherenkov muon veto, XENON1T will probe scattering cross-sections of σSI∼ 2×10−47 cm2 within 2 years of operation.
As construction of XENON1T is about to start, we will review its design, science prospects, status and outlook. Additional individual contributions will discuss detailed aspects of ongoing development.
