The injection line and central region design of cyciae-70
CYCLOTRONS 2010 - 19th International Conference on Cyclotrons and Their Applications(2011)
摘要
A 70MeV compact cyclotron is under design at CIAE, which is aimed to provide both proton and deuteron by stripping two electrons from H- beam and D- beam respectively. Both of the negative charged beams are produced in a single external multi-cusp ion source, injected axially by a low energy beam injection line and bent onto the median plane through a spiral inflector. In the central region, the electrode structures and the shape of Dee tips are constructed and optimized to achieve matching at the inflector exit and to maximize the acceptance of the central region. The preliminary design results of the injection line, the spiral inflector and the central region are elaborated in the paper.
