Characterization of linear quadrupoles operated with amplitude-asymmetric sinusoidal waveforms

Year: 2025

Type: article

Abstract: The stability regions formed by the asymmetric sinusoidal shape of the periodic supply potential of the quadrupole mass filter are calculated, with the signal duty cycle d = 0.5 . Two cases are considered, when A 1 < A 2 and A 1 > A 2 , where A 1 and A 2 are the amplitudes of the positive and negative parts of the sinusoid. Stability islands are revealed, where the QMF operation is possible by changing amplitude A 2 without DC potential. For the values A 1 = 1 and A 2 = 0.8 , the mass selected instability mode with a resolution of about 7000 is found. In this island, the potential well depth reaches its maximum along the Y coordinate. At the amplitudes A 1 = 1 and A 2 = 1.8 − 2.0 , stability regions are formed, the operation in which allows reaching R 0.5 = 2000 . The results of the transmission and excitation contours modeling confirm the validity of the method for calculating the stability diagrams of a linear quadrupole with asymmetric sinusoidal waveform.
