  ABSTRACT: We have built an ion treatment system for TWT multistage depressed collectors (MDCs), and investigated the process for secondary electron emission (SEE) suppression. It is found that SEE ratio for oxygen-free high-conductive copper (OFHC) plates is closely related to deposition rate of Mo and surface texture. With the optimized process, SEE ratio has been reduced to a half of the untreated (OFHC).

  ABSTRACT: Attenuator has been designed to meet the strict requirements in W-band for folded waveguide TWT. Synthetical analysis of parameters is carried out, and using microwave studio simulation results show design has good performances. Fabrication technology and test system are in progress to develop the practical attenuator.
