Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

A simple method for the determination of the energetic parameters of the T(d,n)4He neutron beam from a solid titanium-tritium target is described. The energetic parameters under consideration are: the value of the neutron energy, the neutron energy spread in the beam, the mean deuteron interacting energy, and/or the mean deuteron energy loss in the target. The proposed method is based on an accurate measurement of the energy and the full-width at half-maximum of the T(d,n)4He neutron beam. The measurements are made at the angle under consideration and at 95 deg as a reference angle of the neutron direction relative to the deuteron beam direction. The parameters are obtained by a comparison between the measured results at these two angles. The method does not require any additional measurement equipment other than the standard system used in fast neutron spectra measurements, i.e., a 2- × 2-in. NE-213 liquid scintillator in conjunction with the FORIST unfolding procedure to process the proton recoil spectra into energy spectra.
