Enhancing Beam Stability in High-Intensity Synchrotrons Through Modified Resonance Driving Terms

Recent simulations have explored the challenges posed by space-charge-induced resonance crossings in high-intensity synchrotrons, specifically within the context of the High Intensity Heavy-Ion Accelerator Facility Booster Ring (HIAF-BRing). The study, conducted by Cheng Guo and colleagues, introduces a modification to the Resonance Driving Terms (RDTs), termed modified RDTs, aimed at compensating for the adverse effects of space charge and magnetic field imperfections during resonance crossings.

The simulations demonstrated that these modified RDTs significantly mitigate emittance growth and reduce distortion in the phase space during half-integer and third-order resonance crossings. This advancement is crucial as it addresses a notable limitation in beam intensity, which is essential for the efficiency and effectiveness of synchrotron operations.

The findings suggest that implementing these modifications could enhance the performance of high-intensity synchrotrons, potentially leading to more stable and higher-quality beams. This could have far-reaching implications for various applications in particle physics and materials science, where precise beam control is paramount.
