摘要

在电子存储环中,准确描述三整数共振附近的粒子动力学对于各种应用至关重要。传统的方法是将远共振动力学推导到近共振,但困难在于非线性失谐参数在这一临界点会发散。在这里,我们通过对典型扰动理论的适当应用,推导出一个在共振附近表现良好的修正失谐参数。由此得出的理论能准确描述共振岛在广泛参数空间内的形态,并有助于对其进行优化。

Revised Hamiltonian near third-integer resonance and implications for an electron storage ring
In electron storage rings, an accurate description of particle dynamics near third-integer resonance is crucial for various applications. The conventional approach is to extrapolate far-resonance dynamics to near resonance, but the difficulty arises because the nonlinear detuning parameter diverges at this critical point. Here we derive, via a suitable application of the canonical perturbation theory, a revised detuning parameter that is well behaved near resonance. The resultant theory accurately describes the morphology of resonance islands for a wide range of parameter space and facilitates its optimization.
