四极质量过滤器 RF/DC 电压计算
U and V are the DC and RF components of the voltage difference between opposite rod pairs (not the offset from ground).
Formula (Mathieu parameters)
a = 8eUm ω² r₀²
q = 4eVm ω² r₀²
⇒
U = a · m · ω² · r₀²8e
V = q · m · ω² · r₀²4e
e = 1.602×10⁻¹⁹ C; m in kg; r₀ in m; ω = 2πf (f in Hz)
