An example of a sought-after shape is a linearly-ramped current profile that can significantly improve the transformer ratio in beam-driven acceleration, or produce energy-modulated pulse for, e.g., the subsequent generation of THz radiation. In this contribution we discuss the possibility of generating ramped bunches directly via photoinjection; and discuss the longitudinal shaping of the laser-pulse to accommodate for the early space charge dominated time experienced by the bunch. Finally, we demonstrate via particle-in-cell simulations the production of a quasi-ramped 6.9-MeV/c electron bunches suitable for beam-driven acceleration.Read More
