The establishment of steady-state evaporation of the anode in vacuum breakdown is discussed. It is shown that the vapor velocity is determined as the velocity with which a gaseous sphere with internal energy equal to 2 kT//s//u//r expands into vacuum. The temperature T//s//u//r is determined by the balance between the energy release of the electron beam in the anode material and the energy loss due to evaporation. Experimental and calculated data are compared.
