XENONnT Instrument Paper
Render of XENONnT
The multi-staged XENON program at INFN Laboratori Nazionali del Gran Sasso (LNGS) aims to detect dark matter with two-phase liquid xenon time projection chambers of increasing size and sensitivity. The XENONnT experiment is the latest detector in the program and features an active target of 5.9 tonnes of cryogenic liquid xenon (8.5 tonnes total mass in cryostat). The experiment is expected to extend the sensitivity to WIMP dark matter by more than an order of magnitude compared to XENON1T, thanks to the larger active mass and the significantly reduced background, improved by novel systems such as a radon removal plant and a neutron veto.
The article, co-authored by Freiburg's professor for experimental astroparticle physics Marc Schumann, describes the XENONnT experiment and all its its sub-systems in detail and reports on the detector performance during the first science run. A world-record low background level could be achieved with XENONnT.
