The physics in a hollow cathode operated in the arc mode is studied. The distributions of plasma parameters in the cathode cavity are measured. The primary emission mechanism is thermionic emission from the surface of the cathode, which is in contact with the highly ionized plasma. The current flow, the energy balance in the hollow cathode, and the dependence of plasma parameters on pressure and the emission current are studied. The depth to which the plasma penetrates the cathode cavity depends on the applied voltage, the gas pressure, and the emission current density.
