Plasma-based accelerators can provide ultrahigh accelerating gradient which is 3~4 orders of magnitude higher than conventional technology, holding the potential for a revolution in particle accelerators. This novel technology therefore has been given high expectations for the development of compact free-electron lasers. SXFEL is a single-pass FEL user facility that provides 2~10 nm radiation for fundamental and applied research. In frame of this report, we present concept and design of a large-bandwidth XFEL based on a plasma wakefield accelerator (PWFA) driven by SXFEL electron beams. An ultrabroad bandwidth is achieved by chirping the electron beam in a hollow-channel plasma and simulations demonstrate that a spectral bandwidth of up to 24% can be obtained in this scheme. We will also present the recent progress on the construction of PWFA-based XFEL experimental station at SXFEL, and the preliminary experimental results on the PWFA and FEL radiation generation.
