    We explored mean repetition frequency of filamentary streamers for the hollow needle to plate DC electrical discharge with the nitrogen flow through the needle. The frequency was determined by analyzing time-resolved discharge voltage and current waveforms together with emission intensity profiles induced by streamers. For the distance between the tip of the needle and the surface of the plate electrode between 2-6 mm and nitrogen flow ranging between 1-10 slm respectively, the streamers mean repetition frequency varies between 0.1-15 kHz.

    Zkoumali jsme střední opakovací frekvenci filamentárních streamerů stejno-směrného dusíkového výboje v konfiguraci kladná dutá jehla – rovina. Frekvence byla určena analýzou voltampérových a emisních charakteristik streamerového výboje. Pro vzdálenosti jehla – rovina v rozsahu 2-6 mm a průtoku dusíku v rozsahu 1-10 slm, je střední opakovací frekvence produkce streamerů v rozmezí 0.1-15 kHz.
