“…They do not require vacuum systems and are cost-effective. The common types of low-temperature plasma are direct current [1], alternating current (AC, 50 -60 Hz) [2], audio frequency (AF, <100 kHz) [3], ra-dio frequency (RF, 13.56 MHz) [4], and microwave (2.45 GHz) [5].…”

“…Nonthermal plasmas are produced by some devices such as glow, corona, APPJ [6], DBD [7], MHCD [1], etc. Because the ions and the neutrals remain relatively cold, this characteristic provides the possibility of using cold plasmas for low temperature plasma chemistry and for the treatment of heat sensitive materials including polymers and biological tissues.…”

“…Figure 3 shows a schematic diagram of the ANPJ electric circuit. A low-cost commercially available Neon power supply is utilized in the ANPJ to generate the plasma jet in order to cut the overall cost of the device by 1 Electrode system location 10 mm The Nitrogen gas is fed by a 7 m 3 cylinder with pressure of 200 bar through a regulator, which can fed the gas with flow rate ranging from 0 to 25 L/min. The diagnostic tools arrangement used in this work are shown in Figure 4.…”

The construction and operation of atmospheric nonthermal plasma jet, ANPJ, are presented in this work as well as the experimental investigations of its electrical parameters, the configuration of plasma jet column and its temperature. The device is energized by a low-cost Neon power supply of (10 kV, 30 mA, and 20 kHz) and the discharge takes place by using N2 gas with different flow rates from 3 to 25 L/min and input voltage of 6 kV. Diagnostic techniques such as voltage divider, Lissajous figure, image processing and thermometer are used. The electrical characteristics of discharge at different flow rates of N2 gas such as discharge voltage, current, mean power, power efficiency, and mean energy have been studied. The experimental results show that the maximum plasma jet length of 14 mm is detected at flow rate of 12 L/min. The results of plasma jet (heavy particles) temperature along the jet length show that jet plasma has approximately a room temperature at the jet column end. The results of zero flow rate effect on the ANPJ operation show damage in the Teflon insulator and a corrosion in the Aluminum electrodes.

“…Atmospheric Pressure Microplasma Jet (APMJ) can be generated through a number of configurations, generally using noble gases [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The APMJ are suitable for industrial and research applications, such as surface modification, biological material sterilization, biomedical applications (dermatological, dental, etc.…”

“…Deposition of hydrogenated amorphous carbon films and silicon oxide films has been tested using Ar/C 2 H 2 and Ar/ hexamethyldisiloxane/ O 2 mixtures, respectively. Mohamed et al [20] performed microplasma where the electrode's opening was about 200 µm diameter. They measured T g by evaluating the rotational (0 -0) band of the second positive system of N 2 .…”

An atmospheric pressure ac microplasma jet device with Cu spiral-torsion-spring type electrodes was developed.This electrode geometryenables the generation of low power and stable micro plasma jet operated in Ar, He, O 2 , N 2 and air at flux rates ranging from 2 to 12 L/min, applying an ac high voltage at 60Hz frequency. Moreover, the device is absent of dielectric parts which prevents contamination of the plasma. To observe the outflow pattern a Schlieren photography system was used, resulting in broaden and continuous laminar gas flow. Optical emission spectroscopy measurements allow us to infer the mean gas temperature of plasma jet from the outer electrode along its axial position. A temperature decrease of 110℃ to 40℃ was observed up to 5 mm and beyond this gas temperature the plasma jet reaches room temperature, so enabling it to use in treatment of heat-sensitive surfaces such as biomaterials and polymers like polyethylene.
