Neutron Spectrometry with Scintillating Bolometers of LiF and Sapphire 2016 Access copy available to the general public Unrestricted Two scintillating bolometers of LiF (33 g) and Al2O3 (50 g) at 20 mK, inside a lead shielding at the Canfranc Underground Laboratory, were irradiated with neutrons from a source of 252Cf. 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. info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03228 info:eu-repo/grantAgreement/ES/MICINN/FPI-CSD2009-00064 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 1.171 2016 NUCLEAR SCIENCE & TECHNOLOGY 14 / 33 = 0.424 2016 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 173 / 260 = 0.665 2016 Q3 T3 0.565 2016 Electrical and Electronic Engineering 2016 Q2 Nuclear Energy and Engineering 2016 Q2 Nuclear and High Energy Physics 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion (orcid)0000-0003-1190-7233 Cuesta, C.
