Anomalous Peak Formation in the Second Stability Zone of Quadrupole Mass Filters: Role of Non-linear Resonances Induced by Single Rod Defects
Archisman Sinha, Pintu Mandal, Nabanita Deb
Operating a quadrupole mass filter (QMF) within its second stability zone offers superior mass resolving power but introduces extreme sensitivity to structural imperfections. While…
Geometrical Imperfections in a Digital Quadrupole Mass Filter: A Comprehensive Simulation Study in the First Stability Zone
Brotin Taraphdar, Sukanya Jana, Pintu Mandal +1
Geometrical imperfections in quadrupole mass filters introduce higher-order field components that can significantly influence device performance, particularly under non-sinusoidal…
Performance of Quadrupole Mass Filter with Tapered and Flared Geometry
Anushree Dutta, Pintu Mandal, Nabanita Deb
The performance of a quadrupole mass filter (QMF) is highly sensitive to deviations from ideal electrode geometry. In this work, we investigate the effect of small inward and outwa…
Laser-induced, blackbody-radiation-assisted rovibrational cooling of symmetric-top molecular ions: NH3+ and ND3+
Archisman Sinha, Brianna R. Heazlewood, Nabanita Deb
Quantum-state preparation of molecular ions is a prerequisite for precision spectroscopy and controlled studies of cold ion-molecule dynamics. While such control has been extensive…
Influence of octupole field on quadrupole mass filter performance in the second stability zone
Anushree Dutta, Pintu Mandal, Nabanita Deb
Radial asymmetry in a quadrupole mass filter (QMF), introduced by symmetric displacement of a diagonally opposite rod pair, modifies the confinement potential and alters the ion st…
Radial asymmetry in quadrupole mass filters: stability, multipole fields and resolution enhancement
Sukanya Jana, Snigdha Bose, Sayel Chakraborty +2
This study examines the effects of radial asymmetry in a linear quadrupole mass filter with circular rods, introduced either by a change in electrode radii or by displacement of a…
Effect of Rod Asymmetry on Field Distortions and Transmission Characteristics in Linear Quadrupole Mass Filters
Sukanya Jana, Santu Nath, Pintu Mandal +1
This article reports the appearance of the octupole and hexadecapole components in the radial potential, which are otherwise absent in a linear quadrupole mass filter of symmetric…
Determining the nature of quantum resonances by probing elastic and reactive scattering in cold collisions
Prerna Paliwal, Nabanita Deb, Daniel M. Reich +3
Scattering resonances play a central role in collision processes in physics and chemistry. They help building an intuitive understanding of the collision dynamics due to the spatia…
Coulomb crystal mass spectrometry in a digital ion trap
Nabanita Deb, Laura L. Pollum, Alexander D. Smith +4
We present a mass spectrometric technique for identifying the masses and relative abundances of Coulomb-crystallized ions held in a linear Paul trap. A digital radiofrequency wavef…
