(2012). Simultaneous measurement of neutron-induced capture and fission reactions at CERN. European Physical Journal A, 48 (29), 1-9.1434-6001 (impreso)1434-601X (electrónico)https://hdl.handle.net/11441/95349The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the γ-ray background generated in the competing fission reactions. At the CERN neutron time-of-flight facility n TOF we have combined the Total Absorption Calorimeter (TAC) capture detector with a set of three 235U loaded MicroMegas (MGAS) fission detectors for measuring simultaneously two reactions: capture and fission. The results presented here include the determination of the three detection efficiencies involved in the process: εTAC(n,f), εTAC(n,γ) andεMGAS(n,f). In the test measurement we have succeeded in measuring simultaneously with a high total efficiency the 235U capture and fission cross-sections, disentangling accurately the two types of reactions. The work presented here proves that accurate capture cross-section measurements of fissile isotopes are feasible at n TOF.application/pdf9 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1140/epja/i2012-12029-2
