Abstract

One-dimensional (SUNRAY-1D), and two and half dimensional (SUNRAY-2.5D) codes are developed for accurate, fast and reliable multi-signal large signal analysis of a complete helix-type space TWT. Detailed beam and rf field parameters including inter-modulation components and higher-order time harmonics are simulated accurately for a high efficiency space TWT. The spent electron beam data of SUNRAY-2.5D code is used successfully for design of beam refocusing section and multi-stage depressed collectors for various space TWTs. Space TWTs of different frequencies (C-band, Ku-band, Ka-band and W-band), and of different power levels have been designed successfully.
