Diagnosis of Spatial Distribution and Low Energy Level Density of Argon Plasma Jet Active Particles

Abstract

With the deepening of the application of atmospheric pressure low-temperature plasma in the field of biomedicine, the accurate regulation of active particle components and doses also needs to be broken, and all aspects of plasma still need to be studied in depth. Based on this, Ben In this paper, a needle-ring electrode was used to build a plasma discharge device to study the characteristics of 0.1 MPa argon plasma jet number, plasma irradiation at 4 mm, 8 mm, 12 mm, 16 mm, 20 mm away from the nozzle was collected degree, analyze the change law of the type and number of active particles in argon plasma. The results showed that argon plasma. The active particles are mainly oxygen atoms and hydroxyl groups; When argon plasma acts on the copper foil, the surface of the copper foil is low in argon. The relationship between the density of energy levels is ns4 > ns5 > ns2 > ns3; Metastable (1s3 and 1s5) number density versus resonant state (1s2 Similar to 1s4), the number density changes the linear type, and the change trend increases first and then decreases with the increase of axial distance. This paper provides methods and ideas for the generation and optimization of argon plasma jet and the optimization of diagnostic methods, and establishes plasmacy. The control model of the descendant provides a reference and basis.
