Outline the XENONnT Computing Scheme at the 2nd Rucio Community Workshop in Oslo

Oslo welcomed all 66 participants of the second Rucio Community Workshop with pleasant weather and a venue which offered an astonishing view about the capital of Norway. The opensource and contribution model of the Rucio data management tool captures more and more attention from numerous fields. Therefore, 21 communities reported this year about the implementation […]

XENONnT talk at Sendai, Japan

On March 8, 2019, Shigetaka Moriyama presented the status of the XENONnT experiment at the international symposium on “Revealing the history of the Universe with underground particle and nuclear research” in Sendai, Japan. The symposium is held by a Japanese research community working on underground experiments and developing low background techniques. Its members are interested […]

Observing the Rarest Decay Process Ever Measured

[Press Release April 2019 – for immediate release. Paper published in Nature and preprint on the arxiv.] The universe is almost 14 billion years old. An inconceivable length of time by human standards – yet compared to some physical processes, it is but a moment. There are radioactive nuclei that wdecay on much longer time […]

On the way to XENONnT

The XENONnT dual-phase xenon TPC requires two regions with different electric fields to drift, extract, and accelerate the small number of ionization electrons that are created by a possible dark matter interaction with xenon nuclei. These fields will be created with a total of five electrodes that are biased at constant electric potentials from top […]

XENON on skis

XENON was present at the ALPS conference in Austria. Chiara Capelli from University of Zurich gave a talk on behalf of the XENON collaboration. The talk focused on the latest XENON1T results on spin-independent and spin-dependent WIMPs, and on the newest results on two-neutrinos double electron capture, with a final status on the XENONnT upgrade. […]

XENON1T talk at Low Radioactivity Technique 2019

Our latest XENON1T paper on details of our analysis was presented at the Low Radioactivity Techniques, a conference focused on low background experiments. In the talk (that you can find here), the response model of the detector, the challenges of background modeling, as well as the used techniques were described. In a low background experiment […]

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. […]
