Calculation of calorimetric effect of thermo-field electron emission

The aim of the calculation presented in this report is to get more data about the specific calorimetric effect (cathode cooling or heating per one electron) of thermo-field electron emission from metals over wide ranges of work functions (e/spl psi/=2.0-4.5 eV), electron temperatures (T/sub e/ 2000-4500 K) and electron field strengths (F=106-108 V cm/sup -1/). For metals most commonly used in vacuum electro-discharge devices (Cu, Nb, Mo, W), the temperature range has been further expanded up to 500-10000 K.
