J-PARC 主环具有三个直段，分别用于注入、慢速提取和快速提取。进样管路经过重新设计，使薄隔垫具有更高的可靠性。可以通过添加额外的踢脚来减少磁场。已经提出了具有更大接受度的快速提取的替代光学器件。在该设计中，薄隔片被大孔径的踢脚所取代。具有任意能量的光束可以从快速提取的相反侧中止。设计了外部中止线，仅通过使用静态四极双合透镜作为焦点，即可将任意能量中止的光束传送至转储处。
The J-PARC Main Ring has three straight sections for injection, slow extraction and fast extraction. Injection line has been redesigned so as to give a higher reliability for the thin septa. The magnetic field can be reduced by adding an extra kicker. Alternative optics for the fast extraction with a larger acceptance has been proposed. In this design, the thin septa are replaced by kickers with a large aperture. Beam with an arbitrary energy can be aborted from opposite side from the fast extraction. An external abort line has been designed to deliver the beam aborted at an arbitrary energy to a dump just by using a static quadrupole doublet for the focus.
