Description
Shanghai soft x-ray free electron laser (SXFEL) facility is China's first x-ray free electron laser facility, which opened to users in 2023. It consists of one 1.5GeV linac, two undulator lines, two beamlines and 6 end-stations. We built a plasma wakefield acceleration (PWFA) platform between the linac and the in-vacuum undulator line, including a 200TW laser system, a pair of IR grating for laser compression and a main chamber for laser-plasma-beam interaction. PWFA based XFEL experiment had been carried out and the saturation of the FEL has been observed. Novel PWFA based FEL schemes are planed to perform in the future, such as multi-color FEL and ultrafast scheme.
