Complex mathematical model and calculation method for high emission gas discharge hollow cathodes
The complex mathematical model and the calculation method are presented, which permit to calculate main local and operation descriptions of high emission gas-discharge hollow cathodes, including the forecast of life-time in steady state operation mode. The mathematical model uses the kinetics descri...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The complex mathematical model and the calculation method are presented, which permit to calculate main local and operation descriptions of high emission gas-discharge hollow cathodes, including the forecast of life-time in steady state operation mode. The mathematical model uses the kinetics description of electrons and electric gas dynamics description of atoms and ions inside the cathode. The state of activator film and surface temperature field are also calculated. Semi-empiric erosion model is based on the thermally stimulated cathode sputtering theory, which is developed by authors. |
