چکیده
Abstract. The article describes results of experimental study of a plasma jet with the use of electric probes. The volt-ampere probe characteristics were determined from measurements with slowly varying biasing potential in the probe circuit. Plasma floating potential and plasma resistance in different positions in the vicinity of plasma jet were determined for various pressures of ambient atmosphere.

Electric Probe Diagnostics of Thermal Plasma Jet at Low Pressures
Introduction The possibility of application of electric probes for diagnostics of thermal plasma jets is limited, especially due to the interaction of the probe with plasma. Nevertheless, some important information can be obtained. Electric probes were used for measurement of plasma potential in arc plasma [Chapman and Jones, 1978; Hrabovský and Konrad, 1991; Popov and Gateval, 2001], and for d...
متن کاملNon-thermal atmospheric pressure plasma source design and construction using Argon as the working gas for wound healing
In this research, a non-thermal atmospheric pressure plasma jet device was constructed for skin wound treatment. For this reason, five mice were treated for five consecutive days for 30 s, in a daily manner. Natural wound healing time was monitored and compared with the treated one in 12 consecutive days. The measurement of voltage, current and power waveforms of the plasma source, the optical ...
متن کاملAnalysis of passive calorimetric probe measurements at high energy influxes
High energy influxes increase the complexity of passive calorimetric probe measurements because of an increasing temperature of the surrounding materials like the probe holder. This leads to a distinctively different evolution of the probe temperature compared to low energy influxes. Different established methods for the analysis of passive calorimetric probe data are presented and it is shown ...
متن کاملOn the use of the double floating probe method to infer the difference between the electron and the heavy particles temperatures in an atmospheric pressure, vortex-stabilized nitrogen plasma jet.
Sweeping double probe measurements in an atmospheric pressure direct current vortex-stabilized plasma jet are reported (plasma conditions: 100 A discharge current, N2 gas flow rate of 25 Nl/min, thoriated tungsten rod-type cathode, copper anode with 5 mm inner diameter). The interpretation of the double probe characteristic was based on a generalization of the standard double floating probe for...
متن کاملتولید و بررسی گوی پلاسمایی و تبدیل آن به جت پلاسمای فشار اتمسفری موجمیکرو
In this work, we first produced microwave plasma ball, then changed the ball into a microwave plasma jet by flowing a working gas through a nozzle. The effect of working gas on the thermal characteristics of the plasma ball and atmospheric pressure microwave plasma jet was investigated. We used resonant absorption scheme by a metallic antenna inside a chamber in which led to the ionization of s...
