Sažetak
Atmospheric pressure plasma jets (APPJs) are developed for various applications in plasma medicine, biotechnologies and for materials modifications [1]. Various designs of plasma sources and choice of operational parameters are used to tailor plasma content suitable for specific application. We use optical emission spectroscopy in order to characterize APPJs operating under normal atmospheric pressure and under-pressure in different background gases. The APPJ electrode was a copper wire with a diameter of 0.1 mm inserted in a 50 mm long and 1.5 mm outer diameter borosilicate glass capillary tube [2]. Power source was the same as in ref. [3], AC at 25 kHz at about 2.5 kV. This capillary plasma source was inserted into a glass tube of 11.5 cm diameter and 150 cm length. In order to maintain under- pressure conditions, the tube was connected to a rotary vacuum pump and vacuum gauge while the gas (for example helium, purity 99.996%) input flow was controlled with mass flow controller in the range of several L/min. The experimental setup allows various diagnostics to be applied: imaging, spatially resolved optical emission spectroscopy, determination of voltage-current curves and E-M probe measurements, versus total pressure and mass flow in the tube. For optical emission spectroscopy we use miniature fibre spectrometer Avantes Sensline with nominal spectral resolution 0.3 nm. We describe different regimes of the APPJ behaviour depending on the total pressure and mass flow, in terms of the jet lengths, and discuss jet operating mode transitions from atmospheric pressure conditions towards vacuum conditions. This work has been supported by Croatian Science Foundation under project #2753.
