THE XENON COLLABORATION

About 200 scientists and students from 30 institutions across the world form the international XENON collaboration, representing more than 25 different nationalities. The collaboration has been searching for dark matter since 2006 with liquid xenon time projection chambers in a series of experiments: XENON10, XENON100, XENON1T and XENONnT. While XENON10 was filled with merely 15 kg of xenon, XENONnT, the newest member of the XENON family, employs a total of 8.6 tonnes.

ORGANIZATION

The XENON Dark Matter Project is managed by the Collaboration Board (CB), a committee composed of the Spokespersons and all of the Principal Investigators (PIs). The CB is the main decision-making body of the XENON collaboration. A PI is the leader of each collaborating institution who carries the scientific and financial responsibility of that institution for the XENON program. Below is the organizational structure and the description of the responsibilities of each management body. Some roles are also filled by senior scientists that are not PIs.
