Výzkumná skupina Diagnostika a modelování plazmatu zaměřuje svůj výzkum na základní problémy fyziky a chemie výbojů a plazmatu v plynech a kapalinách. Pomocí pokročilých experimentálních metod (spektroskopie a elektrická měření) umíme určit základní parametry popisující plazma jako: elektrické pole, rozdělovací funkce elektronů, teplota elektronů a koncentrace důležitých částic. To vše na extrémně malých prostorových a časových škálách.
Naše experimentální pozorování jsou ověřována na základě analytických modelů a počítačových simulací. Numerické modelování nám přináší hluboký vhled do fyziky výbojů plynů a základních jevů odehrávajících se v plazmatu a také nám poskytuje možnost „numerických experimentů“ v podmínkách, které jsou buď velmi nevhodné, nebo mimo dosah konvenčních experimentálních metod. Na základě hluboké odborné znalosti v oblasti fyziky plazmatu spolupracujeme s několika mezinárodními výzkumnými institucemi a partnery z průmyslu.

Several of our colleagues gave talks or presented posters this November in Prague at the 8th Plasma Science & Entrepreneurship Workshop.
Nonlinear nature of sheaths leads to nonlinear VA characteristics and generation of higher harmonic frequencies in capacitively coupled discharges. Higher harmonic frequencies are known to influence heating of electrons, especially at low pressure, and to be very sensitive to number of discharge parameters, which enables to use higher harmonics for monitoring of various deposition and etching processes. The presentation summarizes the topic of probe measurements of higher harmonic frequencies of plasma potential, nonlinear modeling of behaviour of higher harmonic frequencies in capacitive discharges and explanation of the mechanism which leads to the sensitive reaction of higher harmonics on the presence of a deposited or etched thin film.
Nanosecond-pulsed argon plasma generated in barrier discharge is widely used for many different applications and research purposes, e.g. surface treatment or plasma medicine. An important piece of information is the energy coupling between initial discharge and plasma by fast electrons. The time scales relevant for the investigation of the initiating streamer discharge tend to be of the order of hundreds of picoseconds. To obtain detailed insight into the discharge dynamics, the optical emission spectroscopy is enhanced by time-correlated single photon counting with a temporal resolution in a far sub-nanosecond range. Spatially-resolved measurements with a high temporal resolution for several selected radiative transitions of mainly 2p states give insight into the electron-argon kinetics.

Abstract: Streamer discharges are present in many fields of science. They are basic components of atmospheric electricity and frequently utilized sources of non-equilibrium plasmas, both in fundamental research and applications. Three cases from the physics of streamer discharges are discussed in this presentation. In a free space, the quasi-stationary phase of the streamer development is a well understood phenomenon. Nevertheless the very first stages of the initiation of the streamer in pulse driven discharges lack an experimental understanding, mostly due to the diagnostical challenges connected with the high streamer velocity and its stochastic occurrence. Here, we offer an approach for such detailed diagnostics. In a similar way, the complexity and high velocity of streamer discharges developing on dielectric surfaces is the reason for unanswered questions or lack of experimental data in the field. We offer experimentally based answers to two such questions: What amplitudes can the electric field strength reach during the streamer-surface interaction? What is the initiation mechanism of long plasma filaments in surface barrier discharges? We apply the time-correlated single-photon counting-based optical emission spectroscopy to surface and coplanar barrier discharges in atmospheric air to study such phenomena. We show experimentally that the electric field amplitude reaches values of 400 kV/cm as the positive streamer propagates directly on the surface in a coplanar discharge arrangement. Furthermore, we reveal an ultra-fast development of a remotely initiated streamer cascade in the case of surface barrier discharge operated at high overvoltage. We show that this previously unknown mechanism leads to the generation of an intense cathode spot, which is a crucial condition for plasma transition to a highly-ionized state.
Abstract: The dynamical charging of a dielectric BSO target by an atmospheric pressure low-temperature plasma jet is addressed numerically and experimentally, using a two-dimensional fluid model and Mueller polarimetry measurements. The jet geometry is the same in experiments and simulations. The target is placed perpendicularly to the jet propagation and the jet is powered by rectangular pulses of applied voltage of different polarity and magnitude. The axial component of electric field inside the target is quantitatively compared between simulations and experiments, yielding excellent agreement for every studied condition, during and after the pulses. The electric field inside the target is closely related to the charge deposition on the target surface. It is shown that the spatial distribution of electric field inside the target during the pulse takes a different shape according to the jet polarity. Shortly after the pulse, charge deposition of opposite signal to the one of the applied voltage takes place. Finally, in the long time-scales in between pulses, the distributions of leftover surface charges on the target surface and leftover electric field inside the target are dependent on the polarity and magnitude of applied voltage. The discharge dynamics and the reasons behind these differences are investigated.

Atomic hydrogen was measured by means of TALIF in various discharges and flames. Several aspects of the (TA)LIF method, namely partial saturation of fluorescence process, were analyzed.
We developed a theoretical model of the laser-induced fluorescence process, which predicted the shape of fluorescence non-linear dependence on energy of laser pulses. Thanks to that model, we are able to evaluate the LIF measurements also in highly saturated regime. We used this aproach for measurement of concentration of atomic lead produced in hydride atomizers for atomic absorption spectrometry, in order to understand the atomization process. We found out that the lead atoms occur mainly in the centre of the flame atomizers and the key role in atomization process is played by hydrogen atoms.

In order to precisely understand the non-equilibrium of rotational-vibrational state distribution from the investigated spectra without limiting presumptions, a state-by-state temperature-independent fitting procedure is the ideal approach. In this paper, we present an addition of novel software tool developed for this purpose into our previously published software massiveOES, freely available for the scientific community. The introduced tool offers a convenient way to construct Boltzmann plots even from partially overlapping spectra, in a user-friendly environment. We apply the novel software to the challenging case of OH spectra in surface streamer discharges generated from the triple-line of the argon/water/dielectrics interface.

In this study, the need to batch process the massive datasets containing overlapping molecular spectra in order to obtain the spatio-temporal maps of rotational and vibrational temperatures has arisen. However, none of the publicly accessible software packages provides such functionality. We therefore developed a software, massiveOES, specifically to overcome these shortcomings. This software is now freely available to the scientific community. This paper, besides the plasma diagnostics results, also briefly discusses the data processing methods used by our software.
