摘要

在双频Paul陷波器中，研究了由于六极场像差引起的主共振周围的非线性现象。外部正弦驱动力、碰撞阻尼和奇数阶六极势场强调了动力学。基于伪势近似的运动方程可以用具有二次非线性的阻尼驱动Duffing型方程来封装。利用谐波平衡技术，发现陷波器中的电压和频率比对谐振曲线和轴向位移曲线的性质有着深刻的影响。

Nonlinear Resonance in Dual-Frequency Paul Trap on Account of Hexapole Field Aberrations

Nonlinear phenomena around the primary resonance on account of hexapole field aberrations are being investigated in a dual-frequency Paul trap. The dynamics is underlined by an external sinusoidal driving force, collisional damping, and odd-order hexapole potential field. The pseudo-potential approximation-based equation of motion can be encapsulated by a damped-driven Duffing-type equation with a quadratic nonlinearity. Using harmonic balance technique, the nature of the resonance curves and axial displacement curves are found to be profoundly affected by the voltage and frequency ratios in the trap.
