Quadrupole excitation of ions in linear quadrupole ion traps with added octopole fields [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2008
Modeling and experimental studies of quadrupole excitation of ions in linear quadrupole traps with added octopole fields are described. An approximate solution to the equations of motion of ions trapped in a quadrupole with added octopole and dodecapole fields, with quadrupole excitation and damping is given.

Micromotion compensation using dark and bright ion species

open access: yesFrontiers in Quantum Science and Technology
Stray electric fields induce excess micromotion in ion traps, limiting experimental performance. We present a new micromotion-compensation technique that utilizes a dark ion in a multi-species bright-dark-bright linear ion crystal.

Simulating the performance of a distance-3 surface code in a linear ion trap

open access: yesNew Journal of Physics, 2018
We explore the feasibility of implementing a small surface code with 9 data qubits and 8 ancilla qubits, commonly referred to as surface-17, using a linear chain of ^171 Yb ^+ ions.

Nanoparticle Stored with an Atomic Ion in a Linear Paul Trap

open access: yesPhysical Review Letters
Radiofrequency (RF) traps enable highly controlled interactions between charged particles, including reactions between cold molecular ions, sympathetic cooling of one ion species with another, and quantum logic spectroscopy. However, the charge-to-mass ( Q /

Fast switching of the rf trapping field in an ion trap

open access: yesNew Journal of Physics
Radiofrequency ion traps are essential for many experiments, ranging from quantum computing to physical chemistry and fundamental science. However, in some circumstances the trapping fields may cause undesired effects and need to be switched off briefly ...

Ion injection optimization for a linear Paul trap to study intense beam propagation

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2007
The Paul Trap Simulator Experiment (PTSX) is a linear Paul trap whose purpose is to simulate the nonlinear transverse dynamics of intense charged particle beam propagation in periodic-focusing quadrupole magnetic transport systems.

Linear ion trap fabricated using rapid manufacturing technology [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2010
This article presents the design, construction, and test results of a linear ion trap, fabricated using digital light processing (DLP), which is a low-cost 3D layer-based manufacturing technique. The ion trap was incorporated into a portable mass spectrometer system and experimental mass spectrum was obtained for methamphetamine (m/z 182), cocaine (m/z

Modes of oscillation in radiofrequency Paul traps

open access: yesNew Journal of Physics, 2012
We examine the time-dependent dynamics of ion crystals in radiofrequency traps. The problem of stable trapping of general three-dimensional crystals is considered and the validity of the pseudopotential approximation is discussed.
