Description
This study aims to design a practical high-beam-current, high-transmission-efficiency Multi-Beam RFQ. Due to its complexity, current work focuses on a high-beam-current single-beam RFQ design and transverse stability analysis. Simplifying the RFQ transverse structure into a FODO periodic structure and combining the envelope equation with Floquet analysis, we study transverse beam stability, laying a solid foundation for subsequent Multi-Beam RFQ design. Steps: first, start with single-beam RFQ design, master basic principles and core skills for preliminary design; second, improve the simulation program, conduct Multi-Beam RFQ simulations, compare acceleration differences with single-beam RFQ, and clarify causes and improvements; third, use the envelope equation to analyze the periodic structure’s transverse matching section and front-end conditions, and clarify oscillation synchronism and separation of different polarity ions; finally, explore transverse/longitudinal beam motion differences between single-beam and Multi-Beam, analyze their physical mechanisms, support Multi-Beam RFQ optimization, and promote its practicality.
