High average power W-band TWT development

A second full-gain W-Band folded-waveguide TWT is in test. The TWT largely duplicates the design reported on in 2008 [1] and maintains the goals of one-percent-bandwidth, 250 watts of peak power, 100 watts of average power, and small-signal gain near 30 dB.
