Simulations of neutral beam injection systems with WarpX

At Realta Fusion, I worked under Dr. Kai Shih to develop start-to-end particle-in-cell simulations of neutral-beam-injection systems using WarpX.

The project focused on creating reliable simulation workflows and benchmarking the model against established neutral-beam transport results. This work contributed to an APS DPP poster and two IPAC ’26 proceedings:

• WarpX simulation of the plasma meniscus effect in a neutral beam injection system
• Self-consistent WarpX modeling of space-charge neutralization in WHAM-relevant neutral beams
