| Abstract: | Cone shaped cathodes of vacuum microtriodes were simulated by finite element simulation to understand the influences of the cathode structure,the anode voltage and gate voltage on effective emission angle and the anode current.The results showed that the effective emission angle and the anode current depend on the size and shape of the cathode,potential difference between the anode and the gate.The simulated results can be of technological interest in vacuum microtriode fabrication. |
