Description

This study examines laser wakefield acceleration in conical plasma channels and demonstrate their advantages over conventional cylindrical channels. Simulations show that conical geometry provides stabilizing effect on the externally injected electron bunch. Plasma electrons entering the cavity tend to move toward the axis, supporting bunch confinement and improving its structural stability. Although the conical geometry makes standard methods for reducing energy spread difficult to apply, the system naturally develops alternating positive and negative field gradients. By selecting appropriate parameters, these gradients can compensate each other, resulting in a final bunch with low energy spread. Overall, the results indicate that conical plasma channels offer improved laser retention, enhanced focusing, and better bunch transport compared to cylindrical configurations.
