Universidad de Zaragoza Study of the cosmogenic activation in NaI(Tl) crystals within the ANAIS experiment 2018 Access copy available to the general public Unrestricted The direct detection of galactic dark matter particles requires ultra-low background conditions. NaI(Tl) crystals are applied in the search for these dark matter particles through their interactions in the detector by measuring the scintillation signal produced. The production of long-lived isotopes in materials due to the exposure to cosmic rays on Earth''s surface can be an hazard for these ultra-low background demanding experiments, typically performed underground. Therefore, production rates of cosmogenic isotopes in all the materials present in the experimental set-up, as well as the corresponding cosmic rays exposure history, must be both well-known in order to assess the relevance of this effect in the achievable sensitivity of a given experiment. Here, analysis of the cosmogenic studies developed from the ANAIS experiment NaI(Tl) detectors are presented. Installed inside a convenient shielding at the Canfranc Underground Laboratory just after finishing surface exposure to cosmic rays and thanks to the prompt data taking developed, identification and quantification of isotopes with half-lives of the order of tens of days were allowed, and thanks to the long-term operation of the detectors long-lived isotopes have been also identified and quantified. Main results for the activation yields of iodine and tellurium isotopes, 22Na, 113Sn, 109Cd, and tritium are presented in this work, together with the estimate of the production rates for their activation by cosmic nucleons while on Earth''s surface based on a selection of excitation functions over the entire energy range of cosmic nucleons. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-MULTI-DARK-CSD2009-00064 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.153 2018 PHYSICS, PARTICLES & FIELDS 26 / 29 = 0.897 2018 Q4 T3 PHYSICS, NUCLEAR 16 / 19 = 0.842 2018 Q4 T3 0.542 2018 Astronomy and Astrophysics 2018 Q2 Nuclear and High Energy Physics 2018 Q2 Atomic and Molecular Physics, and Optics 2018 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-7158-9794 Amaré, J.
