Description
The worldwide race towards direct dark matter detection in the form of
Weakly Interacting Massive Particles (WIMPs) has been dramatically
accelerated by the remarkable progress and evolution of liquid xenon
time projection chambers. With a realistic discovery potential, XENON100
successfully reached the ultimate project sensitivity for the
WIMP-nucleon cross-sections and set the best limits also on solar axions
and ALPs searches. Furthermore, it recently excluded also main
"leptophillic" models and excluded any annual modulation in electronic
recoils, thus to further challenge the DAMA observations.
To fully explore the favoured parameter space for WIMP dark matter in
search of a first robust and statistically significant discovery, the
next phase of the XENON program is XENON1T, a detector based on 3.5 tons
of LXe. It's aim is to probe WIMP interaction cross-sections above of
order 2e-47 cm2 within 2 years of stable operations. The construction of
XENON1T has been recently completed, scientific data-taking is projected
to start in Spring 2016. The design characteristics and its scientific
reach will be covered in details.
XENON1T subsystems have been already built to host its straightforward
upgrade, XENONnT, that will contain about 7.5 tons of xenon and aims to
gain an additional order of magnitude in sensitivity. Development and
construction started already and will run in parallel to the operation
of XENON1T with installation starting as early as 2018. Direct search
for dark matter with xenon will be the leading technique in the world
for next years.
