Investigation of the Way of Phase Synchronization of a Self-Injected Bunch and an Accelerating Wakefield in Solid-State Plasma

The electron acceleration, in a laser wakefield accelerator, controlled through plasma density inhomogeneity is studied on basis of 2.5-dimensional particle-in-cell simulation. acceleration requires concordance the scale length and shift accelerated bunch relative to wake bubble during acceleration. This paper considers excitation with equal free electrons metals, solid-state (the original idea Prof. T. Tajima), context studying process. As known process, as moves plasma, self-injected shifts along bubble. Then, falls into phase deceleration wave. In this paper, support process by maintaining position using an inhomogeneous proposed. It confirmed that method synchronization proposed article nonuniform leads increase accelerating gradient energy comparison case self-injection homogeneous plasma.
