Understanding the effects of neutron irradiation of materials is one of the outstanding issues in the development of fusion technologies. The impact of this work derives from the opportunity, for the first time in a tokamak operating with a D-T plasma, to deliver experimental results which directly link to the nuclear characteristics of real sam…

"Computational evaluation of N-16 and N-17 measurements for a 14 MeV neutron irradiation of an ITER first wall component with water circuit"
14th International Symposium on Fusion Nuclear Technology (ISFNT-14) Budapest,Hungary, 22-27 September 2019

During ITER operations the water coolant flowing through components such as the first wall, blanket modules, divertor cassettes and vacuum vessel will become activated by high energy neutrons. Two key neutron-induced reactions will occur with oxygen in the water producing the radioactive isotopes, N-16 and N-17, which have relatively short half-liv…

"Neutronics Pre-analysis and the Status of Neutron Spectrum Unfolding for the Development of a Novel Neutron Detector for Fusion"
30th Symposium on Fusion Technology (SOFT), Giardini Naxos, Messina, Sicily, 16-21 September 2018

C.R. Nobs L. W. Packer P. Batistoni B. Colling Z. Ghani M. Gilbert S. Loreti K. Mergia S. Mesoloras I. Michelakaki M. Pillon M. I. Savva I. E. Stamatelatos K. Triantou T. Vasilopoulou

In future fusion power plants, such as DEMO, D-T neutron emission is predicted to exceed 1×1021 neutrons/second. Accurately monitoring neutron energies and intensities will be the primary method for estimating fusion power, and calculating key parameters, including the tritium breeding ratio and nuclear heating.  The Novel Neutron Det…
