The controlled electron injection is reported at a well-defined space and time is reported using quasi-3D particle-in-cell simulations2. An intense Terawatt short laser pulse propagates through the plasma with a localized density bump region. The phase velocity of the wakefield is varied by density modulation, which controls the electron injection3. A comprehensive set of simulations showed the generation of about sub-pico-Coulomb, sub-femtosecond electron bunches with average energy up to 500 MeV. The electron beam reported can be crucial in the generation of the desirable electron beam for FEL drivers. <\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #888888;\"><strong>References<\/strong> <\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #888888;\">[1] E.
