  Thomson scattering x-ray source is an essential scien-tific platform and research tool in x-ray imaging technol-ogy for various fields. Upgrading plan that replacing the 3-meter S-band old linac with shorter high-gradient struc-ture in Tsinghua Thomson scattering X-ray source (TTX) is undergoing so far, aiming to enhance accelerating gradient from 15MV/m to 30MV/m. Detailed parameters of couplers and electromagnetic simulation results of whole acceleration structure are presented in this paper. Finally, mechanical structure and further upgrading re-search on energy with X-band structures are also discussed.

  Tsinghua X-band high power test stand is under con-struction. A new LLRF system based on the original S-band LLRF system has been designed and tested. A 1 U chasses called X-Adapter was constructed, which has the ability of up-converting and down-converting the signals between 2.856 GHz and 11.424 GHz. The goal of the LLRF system development is to modulate and measure the phase and amplitude of the RF signals. The test re-sults are presented and analysed.
