Laboratory of Quadrupole Mass Spectrometry, Ryazan State University named after S.A. Yesenin, Ryazan, Russia.
We consider the operation of a digital linear ion trap with resonance radial ejection and mass selective instability modes. Periodic wave shape has a positive part with amplitude and duration and negative part with amplitude and duration , where is the period. The mapping of the stability diagram, calculations of the well's depth and ion oscillations spectra are presented.

Article Synopsis
- - The work investigates parametric quadrupole resonance by examining the effects of phase modulation on a waveform potential in ion motion within a quadrupole mass filter.
- - It identifies a stability island with promising ion optical features, including a 16% ion transmission efficiency and a high mass resolution of R = 6000, needing 100-150 RF cycles for separation.
- - The study also analyzes the frequency spectrum of the applied potential, highlighting the discovery of resonance frequency and establishing a suitable stability X-island associated with the modulation frequency linked to the Mathieu equation.
