Abstract :
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, eφ=2.0 to 4.5 eV, electron temperatures Tc=2000 to 4500 K, and electric field strengths F=106 to 108 Vcm-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
