Electronics Irradiation With Neutrons at the NEAR Station of the n_TOF Spallation Source at CERN
/ Cecchetto, Matteo (CERN) ; Sacristan Barbero, Mario (CERN) ; Lerner, Giuseppe (CERN) ; García Alía, Rubén (CERN) ; Aguiar, Ygor (CERN) ; Senajova, Dominika (CERN) ; Garcia Infantes, Francisco (CERN) ; Pavon Rodriguez, Jose Antonio (CERN) ; Sabate Gilarte, Marta (CERN) ; Vlachoudis, Vasilis (CERN) et al.
We study the neutron field at the NEAR station of the neutron time-of-flight (n_TOF) facility at CERN, through Monte Carlo simulations, well-characterized static random access memories (SRAMs), and radio-photoluminescence (RPL) dosimeters, with the aim of providing neutrons for electronics irradiation. Particle fluxes and typical quantities relevant for electronics testing were simulated for several test positions at NEAR and compared to those at the CERN high-energy accelerator mixed-field facility (CHARM), highlighting similitudes and differences.

The study of neutron induced reactions on actinides is of great importance both for the design of advanced nuclear systems and for fundamental research. The design of Generation IV reactors, Accelerator Driven Systems (ADS), as well as the study of alternative fuel cycles, such as the thorium fuel cycle, highlight the need for accurate cross-section data.

First measurement of the $^{94}$Nb($n$,$\gamma$) cross section at the CERN n_TOF facility
/ n_TOF Collaboration
One of the crucial ingredients for the improvement of stellar models is the accurate knowledge of neutron capture cross-sections for the different isotopes involved in the $s$-,$r$- and $i$- processes. These measurements can shed light on existing discrepancies between observed and predicted isotopic abundances and help to constrain the physical conditions where these reactions take place along different stages of stellar evolution.In the particular case of the radioactive $^{94}$Nb, the $^{94}$Nb($n$,$\gamma$) cross-section could play a role in the determination of the $s$-process production of $^{94}$Mo in AGB stars, which presently cannot be reproduced by state-of-the-art stellar models.
