Is TWT is a pulsed device?
Yes, a traveling wave tube or TWT is a pulsed device.
What type of microwave tube amplifier used an axial magnetic field and radial magnetic field?
That would be a TWT amplifier (traveling wave tube).
How does a Traveling Wave tube operate?
travelling wave tubes are broad band tubes and do not use cavity resonators unlike klystron which actually are narrow band tubes using cavities . TWT makes use of distributed interaction between an electron beam and travelling wave. to prolong the interaction between the RF and the electron beam , both of them travel with same speed in same direction . where, RF travels with speed of light and the electron beam travels with that of anode volatage . So , to slow the RF speed , helix arrangements are placed inbetween these tubes .
Why An attenuator is used with TWT?
To prevent saturation

What was king Tutankhamon also called?
nb ḫprw r՚ twt ՚nḫ imn, read like Nebkheperura Tutankhamon. But this is the new name he took, when he became a king. The birthday name was twt ՚nḫ itn, Tutankhaton.
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
Do wolves live in the rainforest?
We guess that wolves live in the rainforest. YES!
Why was Tutankhamun changed to Tutankhamun?
It was not changed - both of those versions are modern attempts to pronounce the ancient Egyptian Twt.'nx.imn. This is how it is written out in hieroglyphs, without any vowel sounds - the "i" is a guttural consonant that does not exist in English.Since Egyptologists have no hope of pronouncing Twt.'nx.imn when they want to speak about him, they say either Tutankhamun or Tutankhamen; they could also say Tewetinkhamon and be just as inaccurate. Since we can never know how it was said in ancient Egypt, any modern version is just as good as any other.There is a theory that the king's original name was Twt.'nx.itn (Tutankhaten) but there is little or no evidence for this.
How does a backward wave oscillator work?
The BACKWARD-WAVE OSCILLATOR (BWO) is a microwave-frequency, velocity-modulated tube that operates on the same principle as the Traveling Wave Tube. However, a traveling wave that moves from the electron gun end of the tube toward the collector is not used in the BWO. Instead, the BWO extracts energy from the electron beam by using a backward wave that travels from the collector toward the electron gun(cathode). Otherwise, the electron bunching action and energy extraction from the electron beam is very similar to the actions in a Travelling Wave Tube. The typical BWO is constructed from a folded transmission line or waveguide that winds back and forth across the path of the electron beam, as shown in figure. The folded waveguide in the illustration serves the same purpose as the helix in a Traveling Wave Tube(TWT). The fixed spacing of the folded waveguide limits the bandwidth of the BWO. Since the frequency of a given waveguide is constant, the frequency of the BWO is controlled by the transit time of the electron beam. The transit time is controlled by the collector potential. Thus, the output frequency can be changed by varying the collector voltage, which is a definite advantage. As in the TWT, the electron beam in the BWO is focused by a magnet placed around the body of the tube.
