Accessed 2 July 2008 ^ "TWT - Travelling Wave Tubes". A second directional coupler, positioned near the collector, receives an amplified version of the input signal from the far end of the RF circuit. In comparison, in the TWT the acceleration is caused by the interactions with the helix along the entire length of the tube. Cutaway view of a helix TWT. This structure provides a helical waveguide, and hence amplification can occur via velocity modulation.

After this the faster electrons overtake the slower ones, causing the density to rise. A coupled-cavity TWT can achieve 60kW output power. (September 2015).

It's possible the file that you're trying to view may have been moved (or removed) from this web site. Comparison[edit]. (2008). "TWT" has been pronounced by engineers as "twit",[4] and "TWTA" as "tweeta".[5].
