Description
High-intensity proton cyclotrons have widespread applications in scientific research, medical treatments, and industrial processes. As cyclotron technology continues to evolve, the trend leans toward more compact designs with increased beam intensity. Our proposed design involves a 120 MeV/u superconducting H3+ cyclotron named SK1000, capable of achieving 3 times the operational beam intensity through foil stripping. This configuration meets the demand for compact and high-intensity cyclotrons in practical applications. However, the intense space charge effects have significant impact on proton beams during injection, acceleration, and extraction, imposing stricter requirements on magnet design, RF systems, and beam extraction system. Particularly in the magnetic system, we aim to achieve a magnetic field with high precision(±10Gs), strong focusing capability, and excellent isochronism(±0.3‰), while simultaneously meeting the stringent requirement for a large axial acceptance in the central region, as well as realizing a single-turn extraction orbit using a stripping foil. Throughout the design and optimization of the magnetic system, continuous efforts are devoted to exploring and implementing effective methods for enhancing magnetic field performance and efficiency. And We simulated the baseline model of SK1000 by OPAL during acceleration and extraction.
