The neutron facility at NCSR ‘Demokritos’ and neutron activation research activities of NTUA

Abstract At the 5.5 MV Tandem T11/25 Accelerator Laboratory of NCSR “Demokritos” quasi-monoenergetic neutron beams can be produced in energy ranges ∼15–21 MeV by means 3 H(d,n) 4 He reaction, ∼4–11 via 2 ∼2.0–5.3 using H(p,n) reaction and ∼120–650 keV 7 Li(p,n) Be reaction. The maximum flux has been determined to order $10^{5}\text{--}10^{6}\text{ n/cm}^{2}\text{s}$ 10 5 – 6 n/cm 2 s , implementing reference reactions, while variation beam is monitored a BF3 detector BC501A scintillator. have characterized multiple foil activation technique as well extensive simulations used for cross section measurements induced reactions again technique.
