Characterization of a laser filament-induced plasma in air at 10 kHz using optical emission spectroscopy
Malte C. Schroeder, Robin Löscher, Nikita Bibinov +4
The increasing availability of high-power Yb-based ultrafast laser-amplifier systems has opened the possibility of air filamentation at high repetition rates >1 kHz. In this new re…
Two-dimensional spatially resolved measurements of helium metastable densities by tunable diode laser absorption spectroscopy in atmospheric pressure RF plasma jets
David A Schulenberg, Xiao-Kun Wang, Mate Vass +3
Helium metastable species play a critical role in sustaining radio-frequency (RF) driven micro atmospheric pressure plasma jets through Penning ionization and for the generation of…
Synergistic control of radical generation in a radio frequency atmospheric pressure plasma jet via voltage waveform tailoring and structured electrodes
Mate Vass, Xiaokun Wang, Ihor Korolov +2
The synergy between voltage waveform tailoring and structured electrodes is investigated in a radio-frequency (RF) atmospheric-pressure microplasma jet operated in helium with a 0.…
Electronegativity effects on plasma dynamics in He/O RF microplasma jets at atmospheric pressure
Lukas Vogelhuber, Ihor Korolov, Mate Vass +6
This work investigates the transitions between ohmic mode and Penning-Gamma mode in a capacitively coupled radio frequency micro atmospheric pressure plasma jets (CCRF APPJ) op…
Dynamics of reactive oxygen species produced by the COST microplasma jet
Sascha Chur, Robin Minke, Youfan He +9
This study is focused on measuring the densities of the excited molecular oxygen species, O and O, produced in…
Nonlinear Power Absorption in CCRF Discharges: Transition from Symmetric to Asymmetric Configurations
Katharina Noesges, Thomas Mussenbrock
This work builds upon previous studies of nonlinear dynamics in low-pressure capacitively coupled radio-frequency discharges, focusing on the electron power absorption mechanism in…
