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.

Finite β effects on the ICRF minority heating and NBI heating are investigated in the Large Helical Device (LHD) by means of the Monte Carlo simulation code using the numerically calculated magnetohydrodynamic equilibrium. The large Shafranov shift occurs in finite β to change the magnetic field configuration and to alter the particle drift motions. It is found that the change of magnetic field configuration due to finite β effects enhances the losses of high energetic trapped particles produced by ICRF heating. However the clear change of heating efficiency is not observed in finite β. It is also found that the deposition profile of neutral beams is modified due to the Shafranov shift in finite β and the center deposition is enhanced in high density case.
