The Canfranc Underground Laboratory (Spanish: Laboratorio Subterráneo de Canfranc or LSC) is an underground scientific facility located in the former railway Tunnel of Somport under Monte Tobazo (Pyrenees) in Canfranc. The laboratory, 850 m deep protected from cosmic radiation, is mainly devoted to study rarely occurring natural phenomena such as the interactions of neutrinos of cosmic origin or dark matter with atomic nuclei.[2][1][3]

Access to the tunnel containing the laboratory is at the Estación Internacional de Canfranc, a former international railway station in the village of Canfranc.[4][3][5]

As of 2018, the following experiments are ongoing in Canfranc:[6]

ANAIS WIMP dark matter search experiment
ArDM WIMP dark matter search experiment
TREX-DM WIMP dark matter search experiment
BiPo radio-purity of materials experiment
NEXT neutrinoless double beta decay experiment
SuperKGd (also known as SUPERK-GD or under similar names) experiment for mapping of background noise signal for the Super-Kamiokande neutrino telescope in Japan. There is a plan to operate the Super-Kamiokande detector with Gadolinium salt dissolved into the water-mass of the detector. This operation would introduce unknown backgrounds in the neutrino-detection process of Super-Kamiokande, and SuperK-Gd is mapping those backgrounds.
GEODYN underground geology experiment

As of 2018, two further experiments were in proposal stage: CUNA, an underground nuclear astrophysics facility, and GOLLUM underground biology experiment.

As of 2018, the following experiments have completed their activities in Canfranc:

ROSEBUD dark matter experiment
LAGUNA neutrino observatory study (just a study, no real experiment hardware built and no measurements of any sort took place).
