As shown in figure 1(a), the experimental setup mainly consists of a plasma jet source and three wells of PBS. The plasma jet source contains a quartz tube, half of which has an inner diameter of 3 mm, and the other half has an inner diameter of 2 mm. The wall thickness of the quartz tube is 1 by: 3. Round 1. Reviewer 1 Report. The authors investigate the electrical, optical and flow characteristics of a ns-pulsed atmospheric pressure plasma jet in Helium impinging on substrates with different electrical properties – conductive, dielectric and liquid.
The main purpose of this research was to introduce a new structure of plasma jet based on mixed electric field to produce a stable Ar–N 2 plasma jet that enhances conventional plasma treatment. The mixed electric field in plasma jet results in a higher electric field distribution through the jet tube that was shown by : Pourya Seyfi, Ahmad Khademi, Saeed Ghasemi, Ali Reza Farhadizadeh, Hamidreza Ghomi. Atmospheric pressure plasma jet (APPJ) has attracted a considerable interest recently due to a variety of reactive species in it 1,2, such as meta-stable particle, OH radical and Cited by: 7.
While operating at the resonance frequency of the PT (88 kHz), plasma jets were generated with input voltages as low as 10 V. The electrical and optical characteristics of the piezoelectric-driven jet were compared to an APPJ produced with a high-voltage sine wave of comparable operating by: 6. On the other hand the addition of the N2 gas doesn’t change the electrical characteristics of plasma discharge significantly. To identify the effectiveness of the CAPPLAT as a tool for sterilization, highly environmental stress resistant bacterial (Bacillus subtilis) endospores were treated for different durations.

The electrical characteristics of the discharge and the appearance of the plasma jet were studied varying the applied voltage amplitude and the gas. Plasma Medical Science describes the progress that has been made in the field over the past five years, illustrating what readers must know to be successful.
As non-thermal, atmospheric pressure plasma has been applied for a wide variety of medical fields, including wound healing, blood coagulation, and cancer therapy, this book is a timely resource on the topics discussed.
We have constructed a plasma jet that can operate in the frequency range kHz and within the range of kV of applied peak-to-peak voltages. High vol-tage probes are used in order to obtain current and voltage waveforms.
In this paper, we will show VRMS-IMRS plasma jet characteristics for the working frequency of 80 kHz. Cur. Abstract: In this paper, a cold atmospheric plasma (CAP) jet array is generated by a 2-D array device of seven CAP jets arranged in a honeycomb configuration and designed with single-electrode configuration as the elemental plasma jet.
The work is motivated by the challenge of using inherently small atmospheric plasmas to address many large-scale processing by: Fundamentals of Electric Propulsion: Ion and Hall Thrusters March The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
