Description
Plasma acceleration is a groundbreaking technology with applications in accelerator and light source facilities, medical and nuclear physics, and beyond. However, their development and optimization rely on computation-ally intensive Particle-in-Cell (PIC) simulations, requiring specialized expertise and multiple simulation tools,significantly limiting broader adoption.
Geant4 [1] is a widely used Monte Carlo (MC) simulation toolkit for modeling particle interactions with matter in high-energy, nuclear, accelerator, medical physics and space science. Many Geant4 applications are adaptable for plasma acceleration, which is currently missing in this toolkit.
We present the first integration of a Machine Learning (ML)-based surrogate model [2-3], trained on PIC simulations, into Geant4 as a particle source. This enables the generation and tracking of plasma-accelerated beams within complete experimental setups, unifying plasma acceleration and MC-based simulations. Our implementation focuses on the PALLAS laser-plasma accelerator test facility [4], integrating its full experimental setup into Geant4. We describe the ML model, its integration into Geant4, and key simulation results, demonstrating the feasibility of start-to-end simulations of plasma acceleration applications within a unified framework.
