Dr. Hoder investigates ultra-fast phenomena in transient non-thermal plasmas using high sensitivity and resolution electrical, optical or spectroscopic techniques. His focus is on fundamental breakdown processes, whether in gases or liquids. He studies the plasma physics and chemistry using non-steady-state radiative-collision and global electrical models. He gave invited talks on international conferences such as IWM 2017, ICPIG 2015 or meetings of European Science Foundation in 2015. He is active as a reviewer for IOP, AIP, IEEE and Springer plasma physics journals. ORCID page: https://orcid.org/0000-0001-5346-6275

In the field of plasma physics I am active namely in laser-based plasma diagnostics, escpecially in (TA)LIF of radical species including measurements in suface discharges ignited at atmospheric pressure. The fluorescence studies contain the research of atomizers, where we have proven by means of TALIF that atomic hydrogen plays the key role in the decomposition of volatile hydrides. Further, I work with capacitively coupled discharges, where I study their ignition and nonlinear characteristics by both theoretical calculations and various diagnostic methods. Regarding other fields of science, I am interested in speleology and occasionally I am in touch with photochemistry and processes in ice.

Adam Obrusník je absolventem doktorského programu Fyzika plazmatu. Ve svém výzkumu se zabýval především numerickými simulacemi, které využívá pro studium kinetiky a dynamiky plynů v plazmatu na atmosférickém tlaku. Během studia se zúčastnil několika výzkumných stáží na univerzitách v Německu, Holandsku a ve Francii. V současné době se kromě plazmatu za atmosférického tlaku věnuje i numerické analýze plazmatu za nízkého tlaku, v iontových motorech a v magnetronovém naprašování.

Mgr. Petr Synek, Ph.D.

e‑mail:

Petr Synek focuses on measurement methodology and processing of data acquired during physical experiments. Lately worked on high precision electrical and optical measurements of dielectric barrier discharges and the development of a statistical approach to such data. Co-author of massiveOES software which provides a way for advanced analysis of emission spectra. Recently had invited talk on SAPP conference with the theme of 'Unraveling the complexity of barrier discharges: rotational non-equilibria and micro-ampere currents'. Internationally collaborates with prof. Jan Benedikt at University of Kiel and Hans Höft at INP Greifswald.

Mgr. Jan Voráč, Ph.D.

e‑mail:

Jan Voráč obtained his Ph.D. in 2014 at Masaryk University in Brno, Czech Republic. His Ph.D. thesis dealt with the thorough investigation of OH radical in atmospheric pressure discharges by laser-induced fluorescence (LIF), including planar thermometry, experimental determination of gas mixing and absolute concentrations. After graduation he worked on spectroscopy mapping, introducing the big data processing software for spectroscopy massiveOES developed together with Dr. Petr Synek. His main research topics are spectroscopy with high spatial and temporal resolution, mapping of quantum states distributions in plasma, spectroscopic thermometry and laser-aided plasma diagnostics.
