Particle-resolved pathways to energetic-ion formation in a fluctuating low-current hollow-cathode plume
Baisheng Wang, Zilong Peng, Yinjian Zhao +1
Energetic-ion formation in a low-current hollow-cathode plume is investigated using experiments, self-consistent electrostatic particle-in-cell (PIC) simulation, and particle-resol…
AlgoPlasma: Open Algorithms for Plasma Modeling
Yinjian Zhao, Zhongping Zhao, Zhe Liu +9
AlgoPlasma is an open-source library in which core numerical algorithms for plasma modeling are implemented as modular, well-documented, and independently testable components. Rath…
Likelihood topology and applicability limits of spatial anti-aliasing inversion for folded electron drift instability dispersion in Hall thrusters
Zilong Peng, Baisheng Wang, Zhongping Zhao +2
The electron drift instability (EDI) is widely recognized as the leading mechanism for anomalous electron transport in Hall thrusters, but its millimeter and sub-millimeter wavelen…
Formation of Anomalously Energetic Ions in Hollow Cathode Plume by Charge Separation Instability
Yinjian Zhao, Baisheng Wang, Tianhang Meng
Hollow cathodes are becoming the bottleneck of many electric propulsion systems, because of the sputtering and erosion on both cathodes and thrusters from the generation of anomalo…
