Radiopurity control in the NEXT-100 double beta decay experiment: procedures and initial measurements 2013 Access copy available to the general public Unrestricted The “Neutrino Experiment with a Xenon Time-Projection Chamber” (NEXT) is intended to investigate the neutrinoless double beta decay of 136Xe, which requires a severe suppression of potential backgrounds. An extensive screening and material selection process is underway for NEXT since the control of the radiopurity levels of the materials to be used in the experimental set-up is a must for rare event searches. First measurements based on Glow Discharge Mass Spectrometry and gamma-ray spectroscopy using ultra-low background germanium detectors at the Laboratorio Subterr´aneo de Canfranc (Spain) are described here. Activity results for natural radioactive chains and other common radionuclides are summarized, being the values obtained for some materials like copper and stainless steel very competitive. The implications of these results for the NEXT experiment are also discussed. info:eu-repo/grantAgreement/ES/FEDER/COMPETE/PTDC-FIS-103860-2008 info:eu-repo/grantAgreement/EC/FP7/240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREX info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio/CSD2007-00042 info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio-2010/CSD2008-00037 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03456 info:eu-repo/grantAgreement/ES/MINECO/FPA2009-13697-C04-04 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.526 2013 INSTRUMENTS & INSTRUMENTATION 21 / 57 = 0.368 2013 Q2 T2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Bandac, I.
