Space-resolved modeling of stationary spots on copper vacuum arc cathodes and on composite CuCr cathodes with large grains

A self-consistent space-resolved numerical model of cathode spots in vacuum arcs is realized on the computational platform COMSOL Multiphysics. The model is applied to the investigation of stationary spots on planar cathodes made of copper or composite CuCr material with large ( 20 µm) chromium grai...
