Simultaneous measurement of neutron-induced capture and fission reactions at CERN
(2012-03)
The 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.-ray ...
Present Status and Future Programs of the n_TOF Experiment
(EDP Sciences, 2012)
The neutron time-of-flight facility n_TOF at CERN, Switzerland, operational since 2001, delivers neutrons using the Proton Synchrotron (PS) 20 GeV/c proton beam impinging on a lead spallation target. The facility combines ...
Neutron induced reactions for the s process, and the case of Fe and Ni isotopes
(2012)
Neutron capture cross sections are the key nuclear physics input to understand nucleosynthesis of the slow neutron capture process (s process). At the neutron time of flight facility n-TOF at CERN neutron capture cross ...
A CVD diamond detector for (n,alpha) cross section measurements
(SISSA, 2012-01)
In astrophysics, the determination of the optical alpha-nucleus potential for low alpha-particle energies, crucial in understanding the origin of the stable isotopes, has turned out to be a challenge. Theory still cannot ...
Neutron measurements for advanced nuclear systems : The n_TOF project at CERN
(2011-12-15)
A few years ago, the neutron time-of-flight facility n_TOF was built at CERN to address some of the urgent needs of high-accuracy nuclear data for Accelerator Driven Systems and other advanced nuclear energy systems, as ...
Measurement of the neutron-induced fission cross-section of Am-243 relative to U-235 from 0.5 to 20 MeV
(2011-12)
The ratio of the neutron-induced fission cross-sections of Am-243 and U-235 was measured in the energy range from 0.5 to 20 MeV with uncertainties of approximate to 4%. The experiment was performed at the CERN n_TOF facility ...
