摘要：介绍了韩国重离子医学加速器（KHIMA）项目中数字间h模漂移管直线加速器（IH-DTL）的KONUS光束动力学设计。利用LORASR代码对碳梁（12c4 +）进行了KONUS光束动力学模拟。IH-DTL工作在200 MHz，将12c4 +束流从0.4 MeV/u的输入能量加速到7 MeV/u的输出能量。优化的目标是提高传输效率，最小化波束发射度增长、波束损耗和工程成本。在RFQ和IH-DTL之间放置有两个间隙和两个四极双极的聚束器。整个IH-DTL包括两个坦克，56个加速间隙，和四个四极三联装置。传动效率达到100%。从RFQ出口到IH-DTL出口的总长度约为507.7 cm。
Abstract The Kombinierte Null Grad Struktur (KONUS) beam dynamics design of the interdigit H-mode drift tube linac (IH-DTL) for the Korea Heavy Ion Medical Accelerator (KHIMA) project is presented. We performed a KONUS beam dynamics simulation for a carbon beam (12 C 4+) with the LORASR code. The 12 C 4+ beam was accelerated from an input energy of 0.4 MeV/u to an output energy of 7 MeV/u by the IH-DTL operated at 200 MHz. The optimization aims were to increase the transmission efficiency and to minimize the beam emittance growth, beam loss, and project costs. The buncher with two gaps and two quadrupole doublets were placed between the RFQ and the IH-DTL. The whole IH-DTL consists of two tanks, 56 acceleration gaps, and four quadrupole triplets. It achieves a transmission efficiency of 100%. The total length from the exit of the RFQ to the exit of the IH-DTL is approximately 507.7 cm.
