| Abstract: | Two kinds of novel helical slow wave circuit, supported by Chemical Vapor Deposition (CVD) diamond, are presented. They are
applying in miniaturized millimeter wave helical traveling wave tube. Cold test characteristic of these circuits are simulated
by MAFIA code. Higher performances are achieved with smaller size, compared with conventional circuit supported by BeO rods.
The nonlinear analysis is implemented by Beam and Wave Interaction (BWI) module, which is a part of TWTCAD Integrated Framework.
Results have been found to be consistent with the expectation. It should be wider apply in microwave and millimeter wave vacuum
electronic devices. |
