Neutron-induced fission cross section of U 234 measured at the CERN n-TOF facility
(2014-04-15)
The neutron-induced fission cross section of U234 has been measured at the CERN n-TOF facility relative to the standard fission cross section of U235 from 20 keV to 1.4 MeV and of U238 from 1.4 to 200 MeV. A fast ionization ...
Measurements of neutron cross sections for advanced nuclear energy systems at n-TOF (CERN)
(2014-04-14)
The n-TOF facility operates at CERN with the aim of addressing the request of high accuracy nuclear data for advanced nuclear energy systems as well as for nuclear astrophysics. Thanks to the features of the neutron beam, ...
The nucleosynthesis of heavy elements in Stars : The key isotope 25Mg
(2014-04-14)
We have measured the radiative neutron-capture cross section and the total neutron-induced cross section of one of the most important isotopes for the s process, the 25Mg. The measurements have been carried out at the ...
238U(n, γ) reaction cross section measurement with C 6D6 detectors at the n-TOF CERN facility
(2014-04-14)
The radiative capture cross section of 238U is very important for the developing of new reactor technologies and the safety of existing ones. Here the preliminary results of the 238U(n,γ) cross section measurement performed ...
Measurement of the angular distribution of fission fragments using a PPAC assembly at CERN n-TOF
(2014-04-11)
A fission reaction chamber based on Parallel Plate Avalanche Counters (PPACs) was built for measuring angular distributions of fragments emitted in neutron-induced fission of actinides at the neutron beam available at the ...
Ni-62(n,gamma) and Ni-63(n,gamma) cross sections measured at the n_TOF facility at CERN
(2014-02-28)
The cross section of the Ni-62(n,gamma) reaction was measured with the time-of-flight technique at the neutron time-of-flight facility n_TOF at CERN. Capture kernels of 42 resonances were analyzed up to 200 keV neutron ...
Experimental neutron capture data of 58 Ni from the CERN n-TOF facility
(2014-01-09)
The 58Ni(n,γ) cross section has been measured at the neutron time of flight facility n-TOF at CERN, in the energy range from 27 meV up to 400 keV. In total, 51 resonances have been analyzed up to 122 keV. Maxwellian averaged ...
A new CVD diamond mosaic-detector for (n, α) cross-section measurements at the n_TOF experiment at CERN
(2013-12-21)
At the n_TOF experiment at CERN a dedicated single-crystal chemical vapor deposition (sCVD) Diamond Mosaic-Detector has been developed for (n,α) cross-section measurements. The detector, characterized by an excellent time ...
High-accuracy determination of the neutron flux at n_TOF
(2013-12-18)
The neutron flux of the n_TOF facility at CERN was measured, after installation of the new spallation target, with four different systems based on three neutron-converting reactions, which represent accepted cross sections ...
Neutron studies for advanced reactors at n-TOF (CERN)
(2013-12)
The neutron time-of-flight facility n-TOF at CERN has been designed to produce cross-section data for neutron induced reactions in the neutron energy range from thermal to GeV. In the first ten years of operation, the ...
