The analysis of nuclear recoils registered by sapphire and (n, a) captures by 6Li shows the feasibility of these cryogenic devices to measure the spectral flux of a neutron field. Data unfolding was done assuming that the spectral flux is a piecewise constant function defined on six energy groups. It can be solved by using non-negative least squares without additional assumptions on the neutron flux. The model provides consistent results with the spectra of the observed events in bolometers, giving a fast neutron flux of F(E > 0.1 MeV) = 0.20 n s-1cm-2 with a 15% uncertainty after 3 hours of live time. After our analysis, it can be concluded that nuclear recoils in sapphire are more useful than (n, a) captures in LiF for spectrometry of fast neutrons. 000056725 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03228$$9info:eu-repo/grantAgreement/ES/MICINN/FPI-CSD2009-00064$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 000056725 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc$$uhttp://creativecommons.org/licenses/by-nc/3.0/es/ 000056725 590__ $$a1.171$$b2016 000056725 591__ $$aNUCLEAR SCIENCE & TECHNOLOGY$$b14 / 33 = 0.424$$c2016$$dQ2$$eT2 000056725 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b173 / 260 = 0.665$$c2016$$dQ3$$eT3 000056725 592__ $$a0.565$$b2016 000056725 593__ $$aElectrical and Electronic Engineering$$c2016$$dQ2 000056725 593__ $$aNuclear Energy and Engineering$$c2016$$dQ2 000056725 593__ $$aNuclear and High Energy Physics$$c2016$$dQ2 000056725 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000056725 700__ $$0(orcid)0000-0003-1190-7233$$aCuesta, C. 000056725 700__ $$0(orcid)0000-0002-9827-2332$$aGarcia, E.$$uUniversidad de Zaragoza 000056725 700__ $$0(orcid)0000-0002-4643-2138$$aGinestra, C. 000056725 700__ $$aGironnet, J. 000056725 700__ $$aDe Marcillac, P. 000056725 700__ $$0(orcid)0000-0002-9043-4691$$aMartinez, M. 000056725 700__ $$0(orcid)0000-0002-2793-7544$$aOrtigoza, Y. 000056725 700__ $$0(orcid)0000-0001-8278-6032$$aOrtiz de Solorzano, A./Puimedon, J.$$uUniversidad de Zaragoza 000056725 700__ $$0(orcid)0000-0001-8732-8196$$aRedon, T.$$uUniversidad de Zaragoza 000056725 700__ $$aRolon, T. 000056725 700__ $$aSarsa, M.L. 000056725 700__ $$0(orcid)0000-0002-7552-1228$$aTorres, L.$$uUniversidad de Zaragoza 000056725 700__ $$0(orcid)0000-0003-0228-7589$$aVillar, J.A.$$uUniversidad de Zaragoza 000056725 7102_ $$12004$$2X$$aUniversidad de Zaragoza$$bDpto.
