Two 12.5¿kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. Present status of ANAIS detectors background and general performance is summarized; in particular, thanks to the high light collection efficiency prospects of lowering the threshold down to 1 keVee are reachable. Crystal radiopurity goals are fulfilled for 232Th and 238U chains and 40K activity, although higher than original goal, could be accepted; however, high 210Pb contamination out-of-equilibrium has been identified. More radiopure detectors are being built by Alpha Spectra. The ongoing high quantum efficiency PMT tests and muon veto characterization are also presented. Finally, the sensitivity of the experiment for the annual modulation in the WIMP signal, assuming the already achieved threshold and background in ANAIS-25 is shown. Further improvement should be achieved by reducing both threshold and background, as expected. 000056328 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/CPAN-CSD2007-00042$$9info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-MULTI-DARK-CSD2009-00064$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 000056328 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000056328 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000056328 700__ $$0(orcid)0000-0002-6948-5101$$aCebrian Guajardo, Susana$$uUniversidad de Zaragoza 000056328 700__ $$0(orcid)0000-0003-1190-7233$$aCuesta Soria, Clara 000056328 700__ $$0(orcid)0000-0002-9827-2332$$aGarcía Abancens, Eduardo$$uUniversidad de Zaragoza 000056328 700__ $$0(orcid)0000-0002-4643-2138$$aGinestra Díaz, Carlos 000056328 700__ $$aMartínez Pérez, María Lucía 000056328 700__ $$0(orcid)0000-0001-7025-061X$$aOliván Monge, Miguel Ángel 000056328 700__ $$0(orcid)0000-0002-2793-7544$$aOrtigoza Paredes, Ysrael Richard 000056328 700__ $$0(orcid)0000-0001-8278-6032$$aOrtiz De Solorzano Aurusa, Alfonso 000056328 700__ $$0(orcid)0000-0003-4492-0936$$aPobes Aranda, Carlos 000056328 700__ $$0(orcid)0000-0001-8732-8196$$aPuimedón Santolaria, Jorge Mario$$uUniversidad de Zaragoza 000056328 700__ $$0(orcid)0000-0002-7552-1228$$aSarsa Sarsa, María Luisa$$uUniversidad de Zaragoza 000056328 700__ $$0(orcid)0000-0003-0228-7589$$aVillar Rivacoba, José Ángel$$uUniversidad de Zaragoza 000056328 700__ $$0(orcid)0000-0002-6519-4315$$aVillar Gómez, Patricia$$uUniversidad de Zaragoza 000056328 7102_ $$12004$$2390$$aUniversidad de Zaragoza$$bDepartamento de Física Teórica$$cFísica Atómica, Molecular y Nuclear 000056328 7102_ $$12002$$2647$$aUniversidad de Zaragoza$$bDepartamento de Física Aplicada$$cOptica 000056328 773__ $$g121 (2016), [5 pp.]$$pEPJ web conf.$$tEPJ web of conferences$$x2101-6275 000056328 8564_ $$s399434$$uhttp://zaguan.unizar.es/record/56328/files/texto_completo.pdf$$yVersión publicada 000056328 8564_ $$s62701$$uhttp://zaguan.unizar.es/record/56328/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000056328 909CO $$ooai:zaguan.unizar.es:56328$$particulos$$pdriver 000056328 951__ $$a2016-09-14-10:13:09 000056328 980__ $$aARTICLE
