The New Canfranc Underground Laboratory (LSC)

Laboratory of Nuclear and High Energy Physics, University of Zaragoza, 50009 Zaragoza, Spain. http://www.unizar.es/lsc

•The Canfranc Underground Laboratory (LSC) is an underground scientific facility devoted to experimental research in Astroparticle and Neutrino Physics since 1985. The LSC is operated by the Research Group on Nuclear and Astroparticle Physics of the Zaragoza University.

•It is located in the Somport railway tunnel (7.8 Km long, not in use). The LSC connects Spain and France across the Central Pyrenees.

Scientific equipment• Low temperature facility (12-20 mK)• Electroforming copper facility (for small pieces)• Underground clean room for R+D on detectors• Ultralow background Ge detectors (for

radiopurity measurements)• Tons of archaeological and very old lead (for

passive shieldings)
