XLZD, Joining forces towards a next-generation Dark Matter experiment

The XENON/DARWIN and LUX-ZEPLIN collaborations have now joined forces to work together on the design, construction, and operation of a new, single, multi-tonne scale xenon observatory to explore dark matter. The detector will be highly sensitive to a wide range of proposed dark matter particles and their interactions with visible matter. Over the last 20+ years, […]

What is Dark Matter made of?

Part of the mystery of Dark Matter is that we know it is there– just not what it is. In Discover magazine you can read about some of the top candidates: https://www.discovermagazine.com/the-sciences/what-is-dark-matter-made-of-these-are-the-top-candidates. The primary candidate that XENON searches for is a Weakly Interacting Massive Particle (WIMP): Including our main spin-independent search, as well as further WIMP  interaction models. […]

Distillation campaign for XENONnT finished

The up-coming XENONnT experiment utilizes a total of 8.3 tonnes of xenon to search for the ever elusive dark matter particles. In addition to the existing 3.3 tonnes of ultra-pure xenon from XENON1T, another 5 tonnes of xenon were purchased by the XENON collaboration.  Before the new gas can be used for XENONnT, it needs […]

XENON at the 2019 Swiss-Austrian Physical Society Meeting

Five members of the University of Zurich group participated at the 2019 Swiss-Austrian Physical Society Meeting in Zurich, Switzerland. Adam Brown contributed with a poster on the XENONnT upgrades and status and Ricardo Peres on the software for the supernova early warning system: Giovanni Volta, Michelle Galloway and Chiara Capelli contributed with talks on the general XENON1T […]

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. […]

Search for light dark matter interactions enhanced by the Migdal effect in XENON1T

When a particle elastically scatters off a xenon nucleus, it has been assumed that electron clouds immediately follow the motion of the nucleus, but in reality it takes some time for the atomic electrons to catch up, resulting in ionization and excitation of the atom. This effect is called the Migdal effect, which was predicted by A. B. Migdal and recently reformulated […]

Talk at Lepton Photon 2019

A talk on the measurement of the double electron capture half-life of xenon-124 with the XENON1T experiment was given at the Lepton Photon 2019 conference in Toronto in August 2019. Ethan Brown from Rensselaer Polytechnic Institute presented this exciting result, demonstrating the power of the ultra-low background in XENON1T. This yielded the measurement of the longest […]
