Description
In Energy Recovery Linacs (ERLs), the beam at the injector exit (including merger) has relatively low energy and remains in the space charge dominated regime. Conventional optical matching alone may lead to beam mismatch in the accelerating cavities, degrading machine performance. Due to the unique characteristics of ERLs, global optimization of the linac optics is often required. However, conventional Particle-In-Cell (PIC) simulations are computationally expensive and time-consuming for optimization purposes. In this study, we employ a modified envelope equation approach. Benchmarking against realistic beam distributions demonstrates excellent agreement with results from conventional simulation codes, while significantly improving optimization efficiency.
