FID generator was used for high-voltage pulse generation of pulse length 7 ns (FWHM) and amplitude up to 110 kV. Chemical activity of the nanosecond discharge was evaluated by measuring the hydrogen peroxide production in water and using phenol as chemical probe. Comparison with the pulsed discharge plasma in liquid operated in microsecond pulse duration range was made in order to assess effects of the input pulse power parameters (pulsed duration) on plasmachemical processes induced by electrical discharge plasma in the liquid. Fundamental issues regarding the mechanism of OH radical formation by the discharge plasma in water will be addressed Workplace Institute of Plasma Physics Contact Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Year of Publishing 2017
