四极磁场边缘场引起的非线性调谐偏移的解析估计

Analytic Estimation of the Non-Linear Tune Shift due to the Quadrupole Magnet Fringe Field

E. Levichev, P. Piminov

摘要:

得到了四极磁场边缘场驱动的振幅相关的调谐位移的解析表达式。的效果的大小进行比较与其他来源的非线性,如色六极,八极误差的主四极磁场和运动学条款。以VEPP-4 M e ~+对撞机的晶格为例进行了计算。

英文摘要:

Analytic expressions for the amplitude-dependent tune shift driven by the quadrupole magnet fringe field have been obtained. The magnitude of the effect is compared with other sources of non-linearity such as chromatic sextupoles, octupole errors of the main quadrupole magnetic field and kinematic terms. A numerical example was the calculation on the lattice of the VEPP-4M e+e- collider.
