Electrostatic solitary waves in ion beam neutralization
Chaohui Lan, Igor Kaganovich
The excitation and propagation of electrostatic solitary waves(ESWs) are observed in two-dimensional particle-in-cell simulations of ion beam neutralization by electron injection b…
Determining Gas Composition for Growth of BNNTs Using Thermodynamic Approach
Alexander Khrabry, Igor D. Kaganovich, Shurik Yatom +4
A high-yield production of high-quality boron-nitride nanotubes (BNNTs) was reported recently in several publications. A boron-rich material is evaporated by a laser or plasma in a…
Benchmarking and validation of global model code for negative hydrogen ion sources
Wei Yang, Sergey N. Averkin, Alexander V. Khrabrov +2
Benchmarking and validation are prerequisite for using simulation codes as predictive tools. In this work, we have developed a Global Model for Negative Hydrogen Ion Source (GMNHIS…
Scaling of Spoke Rotation Frequency within a Penning Discharge
Andrew T. Powis, Johan A. Carlsson, Igor D. Kaganovich +2
A rotating plasma spoke is shown to develop in two-dimensional full-sized kinetic simulations of a Penning discharge cross-section. Electron cross-field transport within the discha…
Analytical model of three regimes of cold cathode breakdown in helium
Liang Xu, Alexander V. Khrabrov, Igor D. Kaganovich +1
An analytical model has been developed to map out the low-pressure (left-hand) branch of the Paschen curve at very high voltage when electrons are in the runaway regime and charge…
Evolution of the electron cyclotron drift instability in two-dimensions
Salomon Janhunen, Andrei Smolyakov, Dmytro Sydorenko +3
The Electron Cyclotron Drift Instability (ECDI) driven by the electron drift in partially magnetized plasmas is investigated with highly resolved particle-in-cell simul…
Design and Implementation of a Thomson Parabola for Fluence Dependent Energy-Loss Measurements at the Neutralized Drift Compression eXperiment
F. Treffert, Q. Ji, P. A. Seidl +10
The interaction of ion beams with matter includes the investigation of the basic principles of ion stopping in heated materials. An unsolved question is the effect of different, es…
Synthesis of nanoparticles in carbon arc: measurements and modeling
Shurik Yatom, Alexander Khrabry, James Mitrani +5
This work studies the region of nanoparticle growth in atmospheric pressure carbon arc. Detection of the nanoparticles is realized via the planar laser induced incandescence (PLII)…
Root-Growth of Boron Nitride Nanotubes: Experiments and \textit{Ab Initio} Simulations
Biswajit Santra, Hsin-Yu Ko, Yao-Wen Yeh +4
We have synthesized boron nitride nanotubes (BNNTs) in an arc in presence of boron and nitrogen species only, without transition metals. We find that BNNTs are often attached to pu…
