PERTURBATION DEVICE FOR CHARGED PARTICLE CIRCULATION SYSTEM

摘要

[PROBLEMS] To obtain a perturbation device for charged particle circulation system in which the distribution profile of a perturbation magnetic field can be formed easily. [MEANS FOR SOLVING PROBLEMS] Perturbation is generated in the orbit of a charged particle by superposing a perturbation magnetic field partially on a main magnetic field for circulating the charged particle, and an incident charged particle is taken into a stable circulation closed orbit. A perturbation magnetic field is formed by utilizing a magnetic field leaking from a magnetic field generated from magnetic field generators (113A, 113B) equipped with a high frequency coil and leaked.
