Description
The high-brightness synchrotron radiation facility “NanoTerasu” provides users with extremely stable synchrotron radiation by top-up injecting an electron beam from a 3-GeV linear accelerator into a diffraction-limited storage ring. NanoTerasu plans to develop a soft X-ray free-electron laser (SX-FEL) using the linear accelerator. To realize SX-FEL with practical gain length, it is required that the linear accelerator generates an electron beam with a peak current of 2 kA and a normalized emittance of 2 mm mrad or less. We have already developed a low-emittance electron gun system with a gridded thermionic cathode and have begun designing a low-emittance injector system using the electron gun system. The linear accelerator based on the electron gun system is planned to serve as both the storage ring’s injector and SX-FEL’s driver. This presentation describes the configuration of a compact SX-FEL linear accelerator that can be installed within existing facilities. It also presents a bunch compression scheme while maintaining slice emittance, along with particle tracking simulation results of the new injector system.
