Optimized scaling for reaching maximum electron energy from laser wakefield accelerator
Original language description
This work explores the optimization of a laser wakefield acceleration setup to maximize the cut-off energy of an accelerated electron beam for a given laser pulse energy. Bayesian optimization, combined with three-dimensional particle-in-cell simulations, is used to determine the optimal laser and plasma parameters under the assumption of a Gaussian laser pulse with a matched spot size and amplitude. The study examines two plasma configurations: a uniform-density plasma and a preformed plasma channel with a matched radius. Additionally, the scalability of the optimized parameters for high-energy laser systems is discussed. The results obtained demonstrate the effectiveness of Bayesian optimization in handling the complex, multi-parametric nature of LWFA and provide insights into designing compact, high-energy electron accelerators.
