Abstract: The main aim of this project is the first measurement of the 33S(n,a)30 Si cross section at the neutron time-of-ight n TOF facility at CERN from few meV to 10 keV, covering the existing lack of experimental data. The measurement was performed in the summer of 2015 in the new beam line of the n TOF facility, n TOF-EAR2. In order to complete the measurement, the characterization of the neutron beam becomes essential to determine the cross section. Therefore, an important part of the present work is dedicated to the description of the n TOFEAR2 features and, in particular, to the evaluation of the neutron ux of the facility by means of combining different cross section measurements considered standards. 33S is a stable isotope of sulphur of interest in Neutron Capture Therapy for treating superficial tumours. The data obtained was included in Monte Carlo simulations of the kerma rate for studying the effect of 33S in the therapy. El objetivo principal de este proyecto es la primera medida de la sección eficaz de la reacción 33S(n,a)30Si en la instalación de tiempo-de-vuelo n TOF del CERN en el rango de energía del neutrón comprendido entre varios eV y 10 keV, cubriendo así l...
