The n_TOF-EAR2 facility at CERN: neutron flux determination and $^{33}$S(n,$\alpha$)$^{30}$Si cross section measurement; implications in BNCT. / Sabate Gilarte, Marta
The main aim of this project is the first measurement of the $^{33}$S(n,$\alpha$)$^{30}$Si cross section at the neutron time-of-flight n_TOF facility at CERN from few meV to10 keV, covering the existing lack of experimental data [...]

Preparation and characterization of  $^{33}$S samples for  $^{33}$S(n,$\alpha$) $^{30}$Si cross-section measurements at the n_TOF facility at CERN / Praena, J (Granada U.) ; Ferrer, F J (CNA, Seville) ; Vollenberg, W (CERN) ; Sabaté-Gilarte, M (Seville U. ; CERN) ; Fernández, B (CNA, Seville ; Seville U.) ; García-López, J (CNA, Seville ; Seville U.) ; Porras, I (Granada U.) ; Quesada, J M (Seville U.) ; Altstadt, S (Goethe U., Frankfurt (main)) ; Andrzejewski, J (Lodz U.) et al. /n_TOF
Thin  33 S samples for the study of the  33 S(n, α ) 30 Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of  33 S powder onto a dedicated substrate made of kapton covered with thin layers of copper, chromium and titanium. This method has provided for the first time bare sulfur samples a few centimeters in diameter. [...]

Geant4 simulation of the n_TOF-EAR2 neutron beam: Characteristics and prospects / Lerendegui-Marco, J (Seville U.) ; Lo Meo, S (ENEA, Bologna ; INFN, Bologna) ; Guerrero, C (Seville U.) ; Cortés-Giraldo, M A (Seville U.) ; Massimi, C (INFN, Bologna ; Bologna U.) ; Quesada, J M (Seville U.) ; Barbagallo, M (INFN, Bari) ; Colonna, N (INFN, Bari) ; Mancusi, D (Saclay) ; Mingrone, F (Bologna U.) et al. /n_TOF
The characteristics of the neutron beam at the new n_TOF-EAR2 facility have been simulated with the Geant4 code with the aim of providing useful data for both the analysis and planning of the upcoming measurements. The spatial and energy distributions of the neutrons, the resolution function and the in-beam $ \gamma$ -ray background have been studied in detail and their implications in the forthcoming experiments have been discussed.

Dose Effect Of The $^{33}$S(n,$\alpha$) $^{30}$Si Reaction In BNCT Using The New n_TOF-CERN Data / Sabaté-Gilarte, M (CERN ; Seville U.) ; Praena, J (Granada U.) ; Porras, I (Granada U.) ; Quesada, J M (Seville U.) /n_TOF
$^{33}$S is a stable isotope of sulphur which is being studied as a potential cooperative target for Boron Neutron Capture Therapy (BNCT) in accelerator-based neutron sources because of its large (n,$\alpha$) cross section in the epithermal neutron energy range. Previous measurements resolved the resonances with a discrepant description of the lowest-lying and strongest one (at 13.5 keV). [...]
