Electronic spectroscopy of cold cations in a 22-pole trap by indirect methods [PDF]
, 2013 The confining capabilities of a 22-pole ion trap have been employed to mea- sure electronic spectra of cations of astrophysical relevance. The ion trap sits on the head of a closed cycle cryostat, enabling collisional cooling of the confined ions with

Conceptual design of an RF multipole plasma transport and trap loading experiment
Results in Physics, 2019 A multipole plasma trap uses radio-frequency electric multipole fields to confine the charged particles of a plasma in a 3D volume. For experimentation with this concept, it is necessary to load the trap with the desired distribution of particles.

Design and implementation of a blade-type linear Paul trap [PDF]
AIP AdvancesIn this work, we present the design, construction, and characterization of a linear Paul trap in a blade configuration. The trap was optimized to minimize micromotion and enable the formation of linear ion chains comprising tens of ions.

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 ...

Accurate modelling of small-scale linear ion trap operating mode using He buffer gas to improve sensitivity and resolution for in-the-field mass spectrometry [PDF]
, 2019 Spectral peak separations of 4 m/z were previously measured using a small-scale mass spectrometer. In this paper the use of He buffer gas during mass analysis was investigated in order to obtain better peak separations (1 m/z) and to optimize the design ...
