Question

name the process of emitting electrons from the heated cathode ?

Answer 1

Cathode heater. ... The cathode heats to a temperature that causes electrons to be 'boiled out' of its surface into the evacuated space in the tube, a process called thermionic emission. The temperature required for modern oxide-coated cathodes is around 800–1,000 °C (1,470–1,830 °F).
