Abstract:
A method for determining the heat effect that accompanies the thermal-field emission of electrons
from metal into vacuum is proposed in the context of a standard model of free-electrons in the metal. Particular attention is given to a quantitative investigation of the cooling regime of a metal surface due to the electron emission. It is demonstrated that for cathodes with low work function on the order of 1 eV, cathode cooling intensity on the order of 10 kW/cm2 can be reached at temperature of 300 K.
