Journal ArticleDOI
Helium metastable species generation in atmospheric pressure RF plasma jets driven by tailored voltage waveforms in mixtures of He and N2
I. Korolov,M Leimkühler,Marc Böke,Zoltan Donko,V Schulz-von der Gathen,Lena Bischoff,Gerrit Hübner,Peter Hartmann,Timo Gans,Yue Liu,Thomas Mussenbrock,Julian Schulze,Julian Schulze +12 more
TL;DR: In this article, the absolute densities of He-I (23S1) metastables in a micro atmospheric pressure plasma jet operated in He/N2 and driven by "peaks"- and "valleys"-type tailored voltage waveforms are presented.
Journal ArticleDOI
Experimental and computational investigations of electron dynamics in micro atmospheric pressure radio-frequency plasma jets operated in He/N2 mixtures
Lena Bischoff,Gerrit Hübner,I. Korolov,Zoltan Donko,Peter Hartmann,Timo Gans,J Held,V Schulz-von der Gathen,Yue Liu,Thomas Mussenbrock,Julian Schulze,Julian Schulze +11 more
TL;DR: In this article, the electron power absorption dynamics in radio frequency driven micro atmospheric pressure capacitive plasma jets are studied based on experimental phase resolved optical emission spectroscopy and the computational particle in cell simulations with Monte Carlo treatment of collisions.
Journal ArticleDOI
Control of electron dynamics, radical and metastable species generation in atmospheric pressure RF plasma jets by Voltage Waveform Tailoring
I. Korolov,Zoltan Donko,Gerrit Hübner,Lena Bischoff,Peter Hartmann,Timo Gans,Yue Liu,Thomas Mussenbrock,Julian Schulze,Julian Schulze +9 more
TL;DR: In this paper, a voltage waveform tailoring approach is proposed for the control of the dynamics of energetic electrons, the electron energy distribution function in distinct spatio-temporal regions of interest, and the generation of atomic nitrogen as well as helium metastables.
Journal ArticleDOI
Disrupting the spatio-temporal symmetry of the electron dynamics in atmospheric pressure plasmas by voltage waveform tailoring.
Andrew Gibson,Andrew Gibson,Zoltan Donko,Layla Alelyani,Lena Bischoff,Gerrit Hübner,Jerome Bredin,Scott Doyle,I. Korolov,Kari Niemi,Thomas Mussenbrock,Peter Hartmann,James Dedrick,Julian Schulze,Julian Schulze,Timo Gans,Deborah O'Connell +16 more
TL;DR: It is demonstrated that tailored voltage waveforms consisting of multiple rf harmonics induce targeted disruption of these symmetries and confines the electron heating to small regions of time and space and enables the electron energy distribution function to be tailored.
Journal ArticleDOI
Atomic oxygen generation in atmospheric pressure RF plasma jets driven by tailored voltage waveforms in mixtures of He and O2
I. Korolov,David Steuer,Lena Bischoff,Gerrit Hübner,Yue Liu,V Schulz-von der Gathen,Marc Böke,Thomas Mussenbrock,Julian Schulze,Julian Schulze +9 more
TL;DR: In this article, the exact atomic oxygen densities measured space resolved in the active plasma volume of a COST microplasma reference jet operated in He/O2 and driven by tailored voltage waveforms are presented.
