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, 780 m deep and protected from cosmic radiation,[2] is mainly devoted to study rarely occurring natural phenomena such as the interactions of neutrinos of cosmic origin or dark matter with atomic nuclei.[3][1][4]

Access to the tunnel containing the laboratory is at the Estación Internacional de Canfranc, a former international railway station in the village of Canfranc.[5][4][6]

Experiments

[edit]

As of 2023, the following experiments are ongoing in Canfranc:[7]

  • ANAIS, WIMP dark matter search experiment
  • DArT, experiment to measure the radioactive activation of argon
  • TREX-DM, WIMP dark matter search experiment
  • NEXT, neutrinoless double beta decay experiment
  • CROSS, Cryogenic Rare-event Observatory with Surface Sensitivity, searching for neutrinoless double beta decay
  • 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.
  • BabyIAXO, preparing the ground for the full infrastructure of the IAXO (International Axion Observatory) which is a new generation axion helioscope and its main goal is to detect axions (or other similar particles) potentially emitted by the Sun’s core in large quantities
  • GOLLUM, underground biology experiment

As of 2023, the following experiments were described as proposals:[8]

  • Multicellular structure formation in response to low level background radiation, a biology experiment
  • Microorganisms with enhanced DNA damage repair abilities, a biology experiment
  • Interaction between host and pathogens under low-radiation background, a biology experiment
  • THE MODERN-E PROJECT, a study of wireless transmission of geotechnical data through clay rocks. Through its works, it aims to achieve a wireless monitoring system capable of operating with the measurement instrumentation commonly used for monitoring the main geotechnical parameters that are relevant for the operation of the future nuclear waste repository
  • CADEX, the Canfranc Axion Detection Experiment
  • Luria-Delbrück 2.0, studying cosmic radiation to evaluate its possible role in the mutation rate of bacteria
  • Bacteria in heavy water, a biology experiment
  • NEXT-HD, the fourth phase of the NEXT program
  • NaI-CGF, this proposal aims to build and commission an underground facility to grow ultra-high radiopurity NaI(Tl) scintillators
  • HENSA, High Efficiency Neutron-Spectrometry Array
  • ARQ-Qubits, aims at developing a new technology to mitigate the effects of radiation on qubits
  • DAMIC, Dark Matter in CCDs, a dark matter detection experiment
  • LU, Low-level γ spectroscopy with High Purity Germanium (HPGe) detectors, a radiopurity experimemt
  • CUNA, an underground nuclear astrophysics facility

As of 2023, the following experiments have completed their activities in Canfranc:[9]

  • ArDM, WIMP dark matter search experiment
  • ETSEC, preliminary study for the Einstein Telescope project
  • BiPo, radio-purity of materials experiment
  • ROSEBUD, dark matter experiment
  • LAGUNA, neutrino observatory study (just a study, no real experiment hardware built and no measurements of any sort took place)
  • GOLLUM, underground biology experiment
