Brief presentation of the institution

The Institute of Plasma Physics of the Czech Academy of Sciences (IPP CAS) is the sole entity in the Czech Republic specializing in the research and applications of plasma. The research includes both experimental and theoretical studies of artificially generated plasma in a broad range of temperatures, densities, and lifetimes. An integral component of this research is the development of adequate diagnostic methods and search for practical utilization of plasma systems. The IPP is an internationally recognised research institution (e.g. many bilateral and multilateral international projects, organiser of many international conferences, EURATOM, LASERLAB, BIOELECTRICS associations), has a total of 150 employees and it is divided into 6 scientific departments.

Main Plasma with liquids related topics

- Elementary chemical and physical phenomena induced by non-equilibrium plasma of electrical discharges in liquids (aqueous, non-aqueous) and in gas-liquid environments (discharge plasma diagnostics, analyses of chemical products of plasma in liquid and gaseous phase, aqueous-phase chemistry of electrical discharge plasma in water and in gas-liquid environments, interactions of plasma with the condensed liquid and at gas/liquid interfaces)

- Development of high voltage discharge (pulsed and DC) generators of various design and electrode geometry producing plasma directly in the liquid, in the gas phase in contact with the liquid or in both phases simultaneously

- Chemical and biological effects of electrical discharge plasma in water and gas/liquid environments and their potential environmental, biological, chemical applications (decomposition of organic pollutants in water, inactivation of microorganisms in water, organic synthesis, etc.)

Main Plasma with liquids related research techniques and equipment

Lab-scale pulse power generators for generation of electrical discharges in liquid:

- monopolar (positive polarity) nanosecond (FWHM ~ 7 ns) pulse high-voltage generator (FID Technology GmbH) for discharge plasma in aqueous and organic liquids (up to 150 kV and 150mJ/pulse into the load 50 Ω, pulse rate 1-100Hz)

 - monopolar sub-microsecond (FWHM ~ 250 ns) high-repetitive pulse high-voltage MPC generator (Suematsu Electronics) for discharge plasma in aqueous liquids (max. 30 kV, 1-500 Hz, 0.3 J/pulse)

- monopolar and bipolar (~µs) pulse high-voltage generators with spark gap switch for discharge plasma in aqueous liquids (± 40 kV, 1-100 Hz, 0.2-5 J/pulse);

- rectangular pulse forming generator with thyratron switch for PEF treatments of highly conductive liquids (2 μs, load 2 kΩ, 50 Hz, max 30 kV, PEF up to 60 kV/cm) ;

- atmospheric pressure plasma jets for biomedical applications: RF in Ar (kINPen), RF in He (EU COST APPJ), DC in air.

Physical diagnostics of discharge plasma:
- high-voltage measurement and fast time resolved systems for data acquisition and processing
- fast multichannel emission spectroscopy and LIF diagnostics
- characteristics of shockwaves by PVDF, FOPH hydrophones and time-resolved Schlieren and shadowgraphy methods
