FIG. 2.

(a) Visual view of the plasma system. (b) Images of afterglow region of the plasma jet in pure helium and He/O mixtures. Total gas flow rate is 3 slm and plasma power is 18 W.

FIG. 3.

Voltage-current waveforms of the plasma jet. (a) Discharge in pure Helium and (b) Discharge in He/O mixture (0.1% Oxygen).

Image of FIG. 4.
FIG. 4.

Optical emission spectra of the active zone region of plasma jet. (a) Discharge in pure helium. (b) Discharge in helium/oxygen mixture (0.1%). Total gas flow rate is 3 slm and plasma power is fixed at 18 W.

Image of FIG. 5.
FIG. 5.

Optical emission spectra of the afterglow region of plasma jet. (a) Discharge in pure helium. (b) Discharge in helium/oxygen mixture (0.1%). Total gas flow rate is 3 slm and plasma power is fixed at 18 W. Emission spectra are recorded at 5 mm after the edge of capillary.

Image of FIG. 6.
FIG. 6.

Experimental and simulated spectra of OH radicals. (a) Discharge in Pure He and in active zone region (between HV and ground electrodes). (b) Discharge in He/O mixture (0.1%) and in active zone region (between HV and ground electrodes). (c) Discharge in Pure He and in the afterglow region. (d) Discharge in He/O mixture (0.1%) and in the afterglow region. Plasma power was fixed at 18 W.
