摘要

<正> A fully superconducting ECR ion source, SECRAL (Superconducting ECR ion source with Advanced design at Lanzhou), is being constructed for the production of intense heavy ion beams of very high charge states, such as Xe30+ and U40+. The superconducting magnet of the SECRAL consists of three axial solenoid coils and six sextupole coils with a cold iron structure as field booster and clamp. What is different from the traditional design is that the sextupole is located outside of the three axial solenoid coils in order to reduce interaction force.
