Kozai mechanism
the qualitative behaviour of a hierarchical three-body system is determined by the initial terms in the expansion, referred to as the quadrupole
(), octupole The octupole term becomes dominant in certain regimes and is responsible for a long-term variation in the amplitude of the Lidov–Kozai oscillations.

Multi-pole field magnet layout method for large-area uniform beam ...
The invention relates to a multi-pole field magnet layout method for large-area uniform beam expansion. The method comprises the steps: sequentially arranging two groups of double-unit quadrupole magnets and an octupole magnet on a beam line, and enabling the two groups of double-unit quadrupole magnets to control the envelope and flare angle of a beam current, thereby enabling the envelope ...
