ILIAS is an Integrated Infrastructure Initiative that has pulled together all of Europe's leading infrastructures in Astroparticle Physics to produce a focused, coherent and integrated project. It aims to improve the existing infrastructures and their operation as well as to organise and structure the scientific community to prepare the best infrastructures for the future.

ILIAS results from an extensive consultation of the scientific community and an internal review process through the Astroparticle Physics European Co-ordination (ApPEC).

Today ILIAS has 21 contractors. Moreover a great number of associated partners will contribute to the activities of ILIAS, though not signatories to the EC contract.

ILIAS will strengthen the new coordination by focusing on the following three scientific poles :

Physics in deep underground laboratories

A large portion of the ILIAS activities will take place in at least one of the four European deep-underground laboratories: the “Laboratorio Nazionale del Gran Sasso” (LNGS, Italy), the “Laboratoire Souterrain de Modane” (LSM, France), the “Laboratorio Subterraneo de Canfranc” (LSC, Spain) and the “Boulby Mine Underground Laboratory” (IUS, Great-Britain).
Within ILIAS, a rapid increase of users is foreseen; these will benefit from dedicated experimental underground areas, ultra-low background instrumentation, cryogenic installations, computing networks and many other technical facilities. To this end, ILIAS coordinates the operations via 1 Transnational Access activity, 3 Network activities (improvement of performance, direct dark-matter detection, and double-ß decay) and 2 Joint Research activities (low-background and double-ß decay new techniques).

Gravitational wave detection

For the technological challenges of this rapidly growing field, 1 Network is designed to structure the activities using the two large European interferometers and the three resonant cryogenic detectors, complemented by 1 Joint Research activity to investigate new materials, new cryogenic techniques and fundamental thermal noise mechanisms.

Theoretical astroparticle physics

This network underpins the experiments and infrastructures of the field. It is designed to encourage cooperative theoretical projects, improve links with experiments, promote better understanding of existing data and help define future projects.

ILIAS coordinates and enhances all major infrastructures of the Astroparticle Physics community in Europe, with a management going far beyond the frame of the present EU contract. The new structuring will favour exchanges on the numerous questions common to the relevant communities, greatly enhancing its organisation and efficiency, and helping to guarantee its long-term sustainability and competitiveness.
