摘要

为了提高束流电流,对CC-30/15回旋加速器进行了升级,该回旋加速器设计用于将负氢离子加速到30 MeV和负氘离子加速到15 MeV。这种修改导致回旋加速器两极通道直径的增加和磁体中心区域元素的变化。为了调整主回旋加速器磁体以适应这些条件,进行了三维计算,以确保离子加速到最终能量的稳定和等时性。特别注意在氢和氘离子模式下,旋转垫片磁场的二次谐波存在时,稳定性的维持。

Maintenance of Beam Stability in a Cyclotron with Isochronism Control for Several Types of Ions Using Rotary Shims

In order to increase the beam current, the CC-30/15 cyclotron designed to accelerate negative hydrogen ions to an energy of 30 MeV and negative deuterium ions to 15 MeV was upgraded. This modification resulted in an increase in the channel diameter in the cyclotron poles and a change in the elements of the central region of the magnet. To adjust the main cyclotron magnet to these conditions, 3D calculations were carried out to ensure stable and isochronous ion acceleration to the final energy. Particular attention was paid to the maintenance of stability in the presence of the 2nd harmonic of the magnetic field from the rotary shims in the modes of hydrogen and deuterium ion.
