Neutron energy spectrum determination near the surface of the JET vacuum vessel using the multifoil activation technique
The activation of foils of zinc, indium, aluminium, copper and magnesium has been used as a means of examining the energy spectrum of neutrons produced by discharges in the Joint European Torus (JET). Several threshold reactions have been used, together with a least-squares unfolding code, to determine the 2.5 and 14 MeV neutron yields produced by the JET plasma. Analysis shows that the energy spectrum produced by downscattered neutrons is satisfactorily calculated with the MCNP neutron transport code.
