[IEEE 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Kyoto, Japan (2018.7.9-2018.7.13)] 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Comparison of experimental and theoretical methods for determining the emission area of multitip field cathodes

摘要： The experimental and theoretical methods for obtaining the values of the emitting surface are considered. The obtained values of the emission area from the experimental current-voltage characteristic are compared with those derived using theoretical calculations and computer simulation.
