Study of scintillation in natural and synthetic quartz and methacrylate 2014 Access copy available to the general public Unrestricted Samples from different materials typically used as optical windows or light guides in scintillation detectors were studied in a very low background environment, at the Canfranc Underground Laboratory, searching for scintillation. A positive result can be confirmed for natural quartz: two distinct scintillation components have been identified, not being excited by an external gamma source. Although similar effect has not been observed neither for synthetic quartz nor for methacrylate, a fast light emission excited by intense gamma flux is evidenced for all the samples in our measurements. These results could affect the use of these materials in low energy applications of scintillation detectors requiring low radioactive background conditions, as they entail a source of background. info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03228 info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-MULTI-DARK-CSD2009-00064 info:eu-repo/grantAgreement/ES/MICINN/CPAN-CSD2007-00042 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.981 2014 OPTICS 27 / 88 = 0.307 2014 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 87 / 260 = 0.335 2014 Q2 T2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Borjabad, S.
