Diagnostics and comparative analyzes of plasma parameters in micro hollow cathode discharges with an open and covered external surface of cathode in helium using an additional electrode

A. Saifutdinov et al.

Summary: Covering the external surface of the cathode improves the current-voltage characteristics of microhollow cathode discharges, allowing the negative glow plasma to occupy more of the discharge volume for better resolution in recording fast electron spectra.

Effect of Laser Radiation on the Dynamics of Active Brownian Macroparticles in an Extended Plasma-Dust Monolayer

Ilnaz Izailovich Fairushin et al.

Summary: Using a modified method of Brownian dynamics, this study simulated the dynamics of macroparticles with a uniform metal coating in a plasma-dust monolayer under laser radiation. By calculating the time dependences of particle displacements for different initial parameters and laser intensities, a relationship was established between the particle displacement and the nonideality parameter of the system.
