Characterized with full-metal structure, high output power and broad bandwidth, microfabricated folded waveguide is considered as a robust slow-wave structure for millimeter wave traveling-wave tubes. In this paper, cold-test (without considering the real electron beam) properties were studied and optimized by 3D simulation on slow-wave structure, for designing a GHz Cited by: This demonstrates that the saturated RF output power of a coupled-cavity TWT can be accurately simulated using cold-test parameters determined with a three-dimensional electromagnetic simulation . features optimizer and parameter sweep tools. In addition, procedures can be automated with Visual Basic for Applications (VBA) macros (ref. 3). In this report, the accuracy and efficiency of MWS for simulating cold-test parameters is established for a ferruled coupled-cavity traveling-wave tube File Size: KB.
A W V-band coupled-cavity traveling-wave tube (CCTWT) is designed using High Frequency Structure Simulator (HFSS) and particle-in-cell (PIC) code in CST Particle Studio. The RF section consists of a series of re-entrant cavities connected together with hollow metallic pipe called drift tube. In this region electron beam interacts with the input RF signal to be amplified. Thus RF section design plays a vital role in deciding the tube performance parameters like gain,File Size: KB.

Its peak output power varies from tens of kW to thousands of kW and average power goes up to few tens of : M K Alaria, Srivastava.
Simulation of cold‐test parameters and RF output power for a coupled‐cavity traveling‐wave tube Wilson, J.D.; Kory, C.L. Backward‐wave oscillation suppression in high‐power broadband helix traveling‐wave tubes. The design and analysis of a high-power wideband sheet-beam coupled-cavity traveling-wave tube operating at V-band is presented. “Simulation of cold-test parameters. and RF output power for. where Q L and Q ext are the loaded and external quality factors, is the angular driving frequency, 0 is the an- gular resonant cavity frequency, ts is the time interval between steps, P f is the forward power, and R/Q is the shunt impedance over the quality factor. In this analysis. An equivalent-circuit representation of the coupled cavity traveling-wave paramietric amplifier is shown in Fig. 2e This particular circuit was chosen for analysis because it has been successfully applied in studying similar problems for traveling-wave-tube amplifiers.7 In .
