Site "Interaction of High-Pressure Arc Plasmas with Thermionic Cathodes"
A fast and robust online tool for simulation of different modes of axially symmetric current transfer from high-pressure arc-discharge plasmas to cylindrical thermionic cathodes, created and maintained by Mikhail Benilov and co-workers. The code computes both the diffuse mode of current transfer and modes with axially symmetric spots and can be used in a wide range of arc currents, plasma-producing gases, and cathode materials and dimensions. The tool also serves as a tutorial that can help to make physicists and engineers working in the field comfortable with multiple solutions describing different modes of current transfer to electrodes in low-temperature plasmas.
