We’ve reached the “Neutrino Fog”

We are thrilled to announce that our paper, “First Search for Light Dark Matter in the Neutrino Fog with XENONnT,” has been chosen as a Physical Review Letters (PRL) Selection of the Year! 🏆 This marks the second consecutive year that the XENON collaboration has received this prestigious recognition. What is the “Fog”? To hunt […]

XENONnT Experiment Achieves Record-Breaking Purity in the Quest for Dark Matter

Innovative Technology Pushes the Boundaries of Ultra-Low Background Physics In the global search for dark matter, the XENONnT experiment at the INFN Laboratori Nazionali del Gran Sasso (LNGS) stands out as one of the world’s most sensitive detectors in the field. This international collaboration, comprising over  190 scientists from 30 institutions worldwide, has achieved a […]

First measurement of a nuclear recoil signal from solar neutrinos with XENONnT

PRESENTATION at the IDM 2024 conference (slides) Today, Wednesday, July the 10th, at the IDM conference in L’Aquila (IT), the XENONnT collaboration announced the first measurement of low-energy nuclear recoils from neutrinos produced in nuclear reactions inside the sun, particularly those involving the element boron. Alongside hypothetical dark matter particles, neutrinos from the sun have […]

First Dark Matter Search with Nuclear Recoils from the XENONnT Experiment

PREPRINT The XENON collaboration presented today results from XENONnT, the latest-generation experiment of the XENON Dark Matter project dedicated to the direct search for Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs). With an initial exposure slightly larger than 1 tonne x year, a blind analysis shows that the data is consistent […]

Light Dark Matter Search Results from XENON1T

XENON1T recently released a preprint with new world-leading constraints on light dark matter particles. The challenge of light dark matter The XENON1T detector aims find the signals of dark matter bouncing off xenon atoms. If such a collision happens, it produces two signals: a small light flash (S1), and a cloud of free electrons that […]

The XENON1T Data Acquisition System

Featuring several kilometers of cables, dozens of analog electronics modules, crates of purpose-built specialty computers, and backed by a small server farm, the XENON1T data acquisition system (DAQ) was designed to put our data onto disks. The XENON Collaboration recently published a technical paper on our DAQ in JINST, of course also available on arXiv. […]
