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, e.g. the cathode cooling or heating per electron, of thermo-field electron emission from metals over wide ranges of work functions, e/spl phi/=2.0 to 4.5 eV, electron temperatures T/sub c/=2000 to 4500 K, and electric field strengths F=10/sup 6/ to 10/sup 8/ Vcm/sup -1/. For metals such as Cu, Nb, Mo, and W, most commonly used in vacuum electron discharge devices, the temperature range has been further expanded up to 500 to 10000 K.
