强流长脉冲离子注入器的研制、用于纵向脉冲压缩的离子能量的精确调制方法、合理的结构尺寸和成本的堆芯材料的选择以及低β区离子束输运的可行方案是长脉冲离子加速器的关键问题。本计画现阶段的重点是磁性材料的特性研究及长脉冲、高通量、低发射度离子注入器的开发。为了精确的电压调制和成本有效的磁芯选择，我们测量了各种铁磁材料在快脉冲激励下的响应。对于强，长脉冲离子注入器，我们提出漂移点扩展等离子体源，压缩（平滑）和扩展（冷却）源等离子体。并根据实验结果对这些问题进行了讨论。
Important issues for the long-pulse induction ion accelerator are (1)the development of high-current long-pulse ion injectors, (2)a method for precise modulation of ion energy for longitudinal pulse compression, (3)core material selection of reasonable construction cost and size, and (4)a realistic scheme for the ion beam transport at low-β region. At the present stage of our project, emphasis has been placed on the characterization of magnetic materials and the development of the long pulse, high flux, low emittance ion injectors. For the precise voltage modulation and cost effective selection of magnetic cores, we measured the response of various ferromagnetic materials under fast-pulse excitation. For the intense, long-pulse ion injectors, we propose drifting point-expanding plasma sources, which compress (smooth out) and expand (cool) the source plasma. These issues are discussed based on some experimental results.
