dc.description.abstract | An accurate calibration of the JET neutron diagnostics with a 14 MeV neutron generator was
performed in the first half of 2017 in order to provide a reliable measurement of the fusion
power during the next JET deuterium–tritium (DT) campaign. In order to meet the target
accuracy, the chosen neutron generator has been fully characterized at the Neutron Metrology
Laboratory of the National Physical Laboratory (NPL), Teddington, United Kingdom. The
present paper describes the measurements of the neutron energy spectra obtained using a highresolution single-crystal diamond detector (SCD). The measurements, together with a new
neutron source routine ‘ad hoc’ developed for the MCNP code, allowed the complex features
of the neutron energy spectra resulting from the mixed D/T beam ions interacting with the
T/D target nuclei to be resolved for the first time. From the spectral analysis a quantitative
estimation of the beam ion composition has been made. The unprecedented intrinsic energy
resolution (<1% full width at half maximum (FWHM) at 14 MeV) of diamond detectors
opens up new prospects for diagnosing DT plasmas, such as, for instance, the possibility to
study non-classical slowing down of the beam ions by neutron spectroscopy on ITER. | es |
