We present the discovery and confirmation of a new negative molecular species, the CH$_4^−$ anion. The experimental realization of this high-spin exciplex was challenging because it overlaps at $m/q = -1$ with O$^-$, commonly present as a pollutant in vacuum systems. Electron detachment cross section (EDCS) showed diametrical differences with O$^-$ EDCS, this leaded to the hypotheses of...

164. Multi-Fidelity Simulation Approach for Negative-Ion Based NBI Development

Joey Eickman (Realta Fusion)

Contributed Oral

Realta Fusion is developing fusion energy technology based on the magnetic mirror confinement concept, in which neutral beam injection (NBI) plays a critical role in plasma heating and fuelling. Designing a high-performance NBI system requires navigating a broad engineering and physics parameter space while ensuring that critical processes are accurately captured. To meet these complementary...
