Implication

Simulation study demonstrates efficient multi-objective optimization of betatron X-ray sources using Bayesian algorithms, suggesting a pathway toward intelligent closed-loop beamline control.

Key Points

Develop an intelligent multi-objective optimization framework to simultaneously enhance the photon yield, critical energy, and source size of compact betatron X-ray sources.
Coupled a multi-objective Bayesian optimization algorithm with particle-in-cell (PIC) simulation tools.
Systematically tuned key laser-plasma interaction parameters, including laser focal position, plasma density, and plasma length, across 90 iterations.
Successfully mapped the Pareto front within 90 iterations, drastically accelerating parameter space exploration over traditional single-objective approaches.
Demonstrated that photon yield and critical energy can be enhanced simultaneously, while identifying source size as the primary limiting trade-off constraint.
