| Abstract: | The superconducting (SC) linac driven free-electron laser (FEL) is an important development direction in the near future. The present statuses of the worldwide SC linac-driven hard X-ray FEL (SC-HXFEL) facilities, including Euro-XFEL and LCLS-II, are overviewed. A candidate scheme of a constructing SC-HXFEL in China based on a 7 GeV SC linac is proposed. The main parameters of the SC-HXFEL are given and the technical routes to achieve FEL power of up to 1000 GW by increasing peak current and adopting tapering technology are discussed. |
