More Information
Summary:This is a field emission type cathode provides equal amount of electrons emitted from each mitter. Even if the gate and emitters are short, it can also prevent the emission channel from imperfection. It can control the amount of moving electrons formed at the channel forming electrode 5 by applying positive voltage at the current controlling electrode. Thus, the amount of current from cathode 4 to emission electrode 9 can be controlled. If the emitter 9 and the gate electrode 7 are short, the current applied to emitter 9 will increase to destroy the channel and no more current is supplied to emitter 9.
