For the electron beam machining process, pulse duration for the electron beam is in range of_____

For the electron beam machining process, pulse duration for the electron beam is in range of_____ Correct Answer 50 μs to 15 ms

EBM the gun is operated in pulse mode. This is achieved by appropriately biasing the biased grid located just after the cathode. Switching pulses are given to the bias grid so as to achieve a pulse duration of as low as 50 μs to as long as 15 ms.
