  SLAC National Accelerator Laboratory is undertaking a project to develop a dielectric wakefield deflector with the goal of enhancing Free-Electron Laser (FEL) operational modes and providing comprehensive bunch diagnostics. The project aims to re-establish and optimize the Fresh-slice operation modes in the recently upgraded Soft X-ray Line (SXR) of the LCLS, a scheme noted for its success in delivering femtosecond, high-power double-pulses within the SXR wavelength range and contributing significantly to research published in high-impact journals. The novel wakefield deflector design incorporates an L-shaped bar and a dielectric wakefield deflector using an anodized aluminum bar, drawing from the successful approaches of teams at DESY and PSI. This single straight, rectangular aluminum L-shaped bar, coated with an aluminum oxide dielectric layer, represents a marked improvement over previous corrugated metal jaw designs. Furthermore, this project explores the potential of this passive streaker as a diagnostic tool for electron bunch phase space, promising exciting advancements in the field of accelerator technologies
