Comparison of neutron emission spectra for D and DT plasmas with auxiliary heating

The DT experimental campaign on JET (1997) represents a major step forward for neutron
emission spectroscopy (NES) diagnostic through the high quality data collected by the Magnetic Proton
Recoil (MPR) spectrometer. These data for different DT plasma heating scenarios were analyzed here to
determine the underlying fuel ion populations which in turn were used to project the 2.5-MeV neutron
emission spectra for deuterium plasmas. The results on neutron spectra for DT and D plasmas in the
same conditions were compared in order to determine the plasma information that could be expected
from NES diagnosis of D plasmas and the instrumental characteristics that would be required. Future
NES experiments would make dual sight line observations possible and the added diagnostic value is also
assessed based on the present results.
