Summary form only given. This contribution deals with the time resolved diagnostics of a non thermal plasma source initially developed at GREMI for biomedical applications. The set up, designed as Plasma Gun1, consists in a cylindrical Dielectric Barrier Discharge reactor flushed with neon or helium at flow rates of a few tens of cm^.min"1, and powered by fast rising voltage pulse of nanosecond...
This paper reports on a new device based on very short pulsed dielectric barrier discharge (DBD), generating plasmas over very long distances (~ m) at atmospheric pressure consisting of plasma bullets close to the type of those reported by Laroussi. These plasma balls are traveling at very high speed, between 106 and 108 cm/s, in flexible dielectric tube at the end of which there is generation of...
Summary form only given. As mercury is a non environmental friendly element, many efforts are made in the field of light sources in order to replace Mercury-based lamps. This contribution deals with the potentialities of Neon Xenon discharges for replacing Mercury ones used in cold hollow cathodes fluorescent tubes. Interest of pulsed excitation (pulse duration: few mus; pulse frequency: few kHz)...
