Under the support of ANSO project, the normal-conducting C-band photocathode electron gun is developed in SSRF/SARI with the cooperation of SLRI. The collaboration project is the basis of C-band photoinjector beam test, and is important to enhance the performance of the future accelerator facilities, the Soft X-ray Free Electron Laser facility (SXFEL).
The first 3.6-cell C-band photocathode electron gun was designed, fabricated, and has been successfully tested by high power at the mega scientific facility which name is Soft X-ray Free Electron Lasers facility (SXFEL). It is capable to work on the stable cathode gradient of 150MV/m, and can approach peak gradient of 180MV/m. The 3.6-cell C-band photocathode gun is the first gun successfully developed all over the world, and it carries out the new record of the cathode gradient. This research was also presented at the International Particle Accelerator Conference 2021 (IPAC 2021).
With the same developing demands, the SSRF team and the SLRI team decided to start the collaboration, and signed the intent of letter under the ANSO framework. Next both teams will work together on the beam test, performance optimization and technique conformation based on the ANSO project support. And the SLRI team is strongly willing to develop their FEL technology based on the researching results of the C-band photocathode gun. The study of the photoinjector promotes the technological development and upgrading accelerator facilities in China and along the Belt and Road, proposes improvements for compact FEL, small medical and process accelerator, and contributes to enhancing the international influence of the ANSO alliance.
Project introduction:
Project title: Research collaboration on Thailand new synchrotron light source facility (SPS-II)
Objectives:
This project is aimed to develop key technology for future light source based on accelerator, and provide schemes for the design and construction of SPS-II. Consequently based on SPS-ii, it can provide advanced research platforms in biology, medicine, environmental science, materials science, condensed matter physics, earth science, chemistry and physics to address common global scientific and technological challenges at the forefront.
Moreover, the project will help to build up the professional team of accelerator, even transfer some techniques to Thailand for SPS-II construction. The project can significantly improve the science and technology level of accelerator along the Belt and Road, and promote scientific and technological cooperation between countries.
