Investigation of electrophysical parameters of cold plasma jet in helium and argon

Experimental studies of cold plasma jet generation parameters initiated by sinusoidal voltage in helium and argon in a single geometry of the discharge device and its interaction with model targets – dielectric plate and culture medium with cancer cells – have been carried out. Dependences of amplitude and frequency of current pulses reaching the target and its temperature under different conditions are investigated. The features and optimal parameters (amplitude and frequency of the initiating voltage, geometry of the interaction zone) and doses of helium and argon plasma jet irradiation for suppressing the viability of cancer cells of human lung adenocarcinoma A549 and breast adenocarcinoma MCF7 were determined.
