Question

what is the function of helix structure IN TWT

Answer 1

HEYY DEAR UR ANSWER..........

A TWT integrated with a regulated power supply and protection circuits is referred to as a traveling-wave-tube amplifier (abbreviated TWTA and often pronounced "TWEET-uh"). It is used to produce high-power radio frequency signals..............

Answer 2

Answer:

As the helix provides least change in Vp phase velocity, it is preferred over other slow wave structures for TWT. In TWT, the electron gun focuses the electron beam, in the gap between the anode plates, to the helix, which is then collected at the collector.
