XLZD Collaboration Meeting 2026

The most recent XLZD collaboration meeting took place from 29 June to 1 July 2026 at the University of Zurich, Switzerland. The meeting brought together collaborators across the science, detector, R&D and infrastructure programmes to review recent progress and discuss the next stages of the project. Sessions covered detector design and scaling, ongoing xenon-detector R&D, the evolving science case, site and infrastructure questions, and collaboration planning. The meeting also provided a valuable opportunity for in-person discussion across working groups as XLZD continues to develop as a next-generation rare-event observatory.

XLZD Meeting 2025

The first meeting as an official collaboration was hosted by the Italian underground laboratory LNGS, from 30 June to 3 July. Topics included early design concepts, ongoing R&D, funding and siting, science requirements and much more. A visit through the underground lab, beneath the Gran Sasso mountain, offered a close look at the XENONnT detector, and the possible location XLZD could one day occupy.

The third joint meeting for the XLZD consortium (now XLZD Collaboration) took place from 15–19 April 2024 at the Rutherford Appleton Laboratory, at Harwell, UK. The detector design book and funding strategies were discussed in a broad forum. Excitement over the imminent formation of the future collaboration which will deliver this definitive instrument was also widespread. Find the agenda here.

The first joint meeting after signature of the MoU has taken place 27-29 June 2022 at KIT (Campus North). Seven topical working groups have been established which will report their initial findings at the meeting as a basis for further discussion: Science, Key messages and figures, Xenon procurement and budget, Timeline, major design questions and scaling, Siting, Branding and communications, and Grassroots group.

Signing Memorandum of Understanding

“XENON, DARWIN and LZ representatives signed a Memorandum of Understanding in July 2021 in which they commit to work together at the next detector, but leave the location open.”
