Planar Laser-Induced Fluorescence system for Space and Phase-resolved Ion Velocity Distribution Function Measurements
Sung Hyun Son, Ivan Romadanov, Nirbhav Singh Chopra +1
In this work, we present a planar laser-induced fluorescence (PLIF) system for two-dimensional (2D) spatial and phase-resolved ion velocity distribution function (IVDF) measurement…
Anticathode effect on electron kinetics in electron beam generated plasma
Nirbhav Singh Chopra, Ivan Romadanov, Yevgeny Raitses
Electron beam (e-beam) generated plasmas with applied crossed electric and magnetic fields are promising for low damage processing of ma…
Report on laser-induced fluorescence transitions relevant for the microelectronics industry and sustainability applications
V. S. Santosh K. Kondeti, Shurik Yatom, Ivan Romadanov +3
A wide variety of feed gases are used to generate low-temperature plasmas for the microelectronics and the sustainability applications. These plasmas often have a complex combinati…
Wavelength modulation laser-induced fluorescence for plasma characterization
Ivan Romadanov, Yevgeny Raitses, Andrei Smolyakov
Laser-Induced Fluorescence (LIF) spectroscopy is an essential tool for probing ion and atom velocity distribution functions (VDFs) in complex plasmas. VDFs carry information about…
Generalized lower-hybrid mode with, density gradient, equilibrium ExB drift, collisions and finite electron Larmor radius: Numerical studies with MATLAB solver
Ivan Romadanov, Andrei Smolyakov, Winston Frias +2
MATLAB solver for general dispersion relation has been developed to study local instabilities in partially magnetized plasmas typical for ExB discharges. Several examples of the Si…
