论文摘要
轴向对称磁场通常用于聚焦颗粒梁。大多数现有的离子低能光束传输线基于螺线管焦点。现代加速器项目利用超导螺线管与超导加速腔的结合来加速高强度颗粒梁。本文讨论了轴向对称磁场中匹配的光束的条件。分析使我们能够最大程度地减少由于非线性空间电荷，晶状体畸变，并最大程度地接受通道，使电磁阀的动力消耗和光束发射率生长。焦点结构中最大束电流的表达式，由于球形像差和非线性空间电荷力引起的束发射力。
Axial-symmetric magnetic field is often used in focusing of particle beams. Most existing ion Low Energy Beam Transport lines are based on solenoid focusing. Modern accelerator projects utilize superconducting solenoids in combination with superconducting accelerating cavities for acceleration of high-intensity particle beams. Present paper discusses conditions for matched beam in axial-symmetric magnetic field. Analysis allows us to minimize power consumption of solenoids and beam emittance growth due to nonlinear space charge, lens aberrations, and maximize acceptance of the channel. Expressions for maximum beam current in focusing structure, beam emittance growth due to spherical aberrations and non-linear space charge forces are derived.
