Abstract
The aim of this work is to study the operation and the construction of pulsed atmospheric pressure plasma jet device, Registration of basic electrical signals using a high voltage probe and Rogowiski coil.
The study Also would be evaluate the effect of PAPPJ on blood parameters, blood coagulation, on the other hand this study aimed to evaluate the effect of gamma radiation on blood parameters and blood coagulation, and make a comparison between the effects of the two type of radiations.
Nonthermal plasma jets generated in atmospheric pressure discharges which represent a rapidly developing technology of great application promises. However, the scope of research is to design an affordable, portable and efficient atmospheric.
Nonthermal plasma jet (APPJ) device used in many applications such as sterilization, blood coagulation, kill bacteria, wound healing, cancer treatment and air purification.
The device is powered with a pulsed high voltage power supply, the power supply is negative dc operated with (0-220) kV,which is used to charge the system from 10 kV to 30 kV.
This design achieves the goals of producing a non-thermal plasma jet under atmospheric pressure and operates with low-cost and available components.
The electrical parameters such as discharge current of about 188 A and 184 A for nitrogen and argon plasma jet respectively and discharge voltage at 6 Kv,the total inductance of the circuit and plasma about 16 µH.
The measurements of plasma light at very near from the nozzle shows that the pulse width is about 40 µs for N2 plasma and 48 µs for argon plasma, but the tail is longer (Several hundred microseconds) .
The velocity of the plasma jet has been observed by time of light using optical Photomultiplier tube, the Measured average plasma velocity is about 1.2x106 cm/sec.
The electron density decreased with increasing electric field for both gases (argon and nitrogen).
The gas temperature remained near room temperature, which would enable these plasma jets to be a dopted for a wide variety of biomedical applications.
