Energy-level structure of ion cloud and crystal in a linear Paul trap
New Journal of Physics, 2014 Ion cloud and crystal are recognized as two distinct states in ion traps, but there is no theory that can describe the energy-level structures of these two states from the perspective of quantum theory. In this paper, we construct a model describing ions

Polarization-gradient cooling of 1D and 2D ion Coulomb crystals
New Journal of Physics, 2020 We present experiments on polarization gradient cooling of Ca ^+ multi-ion Coulomb crystals in a linear Paul trap. Polarization gradient cooling of the collective modes of motion whose eigenvectors have overlap with the symmetry axis of the trap is ...

A combined linear ion trap for mass spectrometry
Journal of the American Society for Mass Spectrometry, 1997 AbstractWe propose a novel ion cyclotron resonance ion trap capable of confining ions even at high pressure. The trap consists of three capacitively coupled axial sections, each composed of four circular cross-section rods parallel to the magnetic field axis.

Mutual storage mode ion/ion reactions in a hybrid linear ion trap [PDF]
Journal of the American Society for Mass Spectrometry, 2005 Ion/ion proton transfer reactions involving mutual storage of both ion polarities in a linear ion trap (LIT) that comprises part of a hybrid triple quadrupole/linear ion trap mass spectrometer have been effected. Mutual ion storage in the x- and y-dimensions arises from the normal operation of the oscillating quadrupole field of the quadrupole array ...

Analysis of Multipolar Linear Paul Traps for Ion–Atom Ultracold Collision Experiments
Atoms, 2021 We evaluate the performance of multipole, linear Paul traps for the purpose of studying cold ion–atom collisions. A combination of numerical simulations and analysis based on the virial theorem is used to draw conclusions on the differences that result ...

Simulation of motion of many ions in a linear Paul trap [PDF]
International Journal of Modern Physics A, 2019 The quadrupole linear Paul trap is one of the key instruments in building highly stable atomic clocks. However, a frequency reference based on a single trapped ion is limited in stability due to the time needed for the interrogation cycle which cannot be further shortened. A promising strategy is the utilization of multiple trapped ions.
