Scientific Description
The Canfranc Underground Laboratory (LSC) is a facility for Underground Science. It is conceived as a Consortium of the Spanish Ministry of Economy and Competitiveness, the Aragon Regional Government and the University of Zaragoza.Located under the Pyrenees mountain El Tobazo, the over burden at the site provides 850 maximum meters shielding from cosmic rays and offers a low background environment for the next generation of experiments exploring the frontiers of particle and astroparticle physics. Other sciences can also profit from the unique underground location, such as geodynamics, environmental sciences, biology, etc.

Support to users and General services

The LSC supports the installation of the experimental apparatuses, built by the users, provides general services (power, water, gases) and also specialised services.

Low background screening

Experiments underground need to use material and components as clean as possible from radioactive traces. The screening is performed with a set of hyper-pure Ge counters. The service can be used also by other users (environment, industrial products, etc.).


Extremely clean copper components are produced by building atom by atom.

Scintillating bolometers

Used for rare venets searches.

Broad band accelerometers

Part of the TOPO IBERIA network.

Laser Michelson interefrometers

High resolution geodynamic continuous monitoringA two-component strain-meter to measure small scale deformation over distances of 70 m inside the Earth.

HP-Ge detectors

Hyper pure Ge detectors are used for producing gamma spectra in samples for the experiments and from the environment (air, water, etc.).

Liquid Ar TPC

Used for dark matter search.

GPS stations

Two GPS stations, which continuously record surface movement, which can be correlated to the strain measurements and the local seismic activity.

High pressure Xe TPC

Used for searching for neutrino less double beta decay.

NaI hyper pure detectors

Used for dark matter searches.
