Design of a low voltage folded waveguide four beam Mini-TWT

Folded Waveguide (FW)mini- TWT based on four beams operating at 6.2 kV with total beam power 2.7 kW has been designed by using NRL design codes. The FW slow wave structure (SWS) has been fabricated and "cold" tested. The results of measurements are compared with design. The status of experimental demonstration of the mini- TWT will be presented.
