The design of new generation fast nuclear reactors requires highly accurate cross-section measurements in the MeV energy region. The 242Pu fission cross section is of particular interest for Pu incineration and nuclear waste production. There are dis

Publikováno v: EPJ Web of Conferences, Vol 146, p 03016 (2017)

Fission Chambers (FC) are often used to determine fission cross sections and to measure the neutron beam flux via standard neutron-induced fission reactions. Thus, the fission detection efficiency is a key parameter. Several methods exist to determin

We have developed a new setup to measure prompt γ-rays from the 235U(nth,f) reaction. The setup consists of two multi-wire proportional counters (MWPCs) to detect the fission fragments, two LaBr3(Ce) scintillators to measure the γ-rays. The highly

Development of an experimental set-up for the measurement of neutron-induced fission and capture cross sections of highly radioactive fissile nuclei

Autor: Companis Iulia, Mathieu Ludovic, Aïche Mourad, Schillebeeckx Peter, Heyse Jan, Barreau Gérard, Czajkowski Serge, Ducasse Quentin, Gunsing Frank, Jurado Beatriz, Kessedjian Gregoire, Matarranz Julie, Tsekhanovich Igor

Publikováno v: EPJ Web of Conferences, Vol 69, p 00005 (2014)

The measurement of neutron-capture cross sections of many actinides is complicated by the difficulty in separating capture γ-rays from the large fission-fragment prompt γ-ray background. For example, current estimates of the capture cross section o

Report

Development of a gaseous proton-recoil detector for neutron flux measurements between 0.2 and 2 MeV neutron energy

Autor: Marini, Paola, Mathieu, Ludovic, Aïche, Mourad, Czajkowski, Serge, Jurado, Beatriz, Tsekhanovich, Igor

Absolute measurements of neutron fluence are an essential prerequisite of neutron-induced cross section measurements, neutron beam lines characterization and dosimetric investigations. The H(n,p) elastic scattering cross section is a very well known
