Fabrication of W-Band Traveling Wave Tube Amplifier Beamstick Using Precision Alignment Techniques

A W-band Serpentine waveguide Traveling Wave Tube (TWT) beamstick using elastic averaging, kinematic coupling and quasi-kinematic coupling precision mechanical alignment techniques was developed. Key components; electron gun, electron beam transport system and circuit each utilize a different alignment technique, leveraging their individual advantages for the specific component requirements.
