O and H production in a He+H2O nanosecond pulsed high-voltage plasma, probed with ps-TALIF Kinetics study using 1D fluid modelling

Research output: Contribution to conferencePosterpeer-review


The spatial and temporal evolution of the density of atomic oxygen and hydrogen in a pin-to-pin atmospheric pressure plasma are measured using the Two-photon Absorption Laser Induced Fluorescence (TALIF) diagnostic with a picosecond excitation and detection system. These measurements are carried out in a mixture of 1 slm helium and 0.1%-0.25% water. The plasma is generated by tailored ns-voltage pulses (voltage rise rate ~80 V.ns-1). A 1D fluid numerical model is validated and used to study the kinetics of O and H in the discharge
