A Theory of Anharmonic Perturbations in a Penning Trap
نویسنده
چکیده
Classical hamiltonian perturbation theory formulated in terms of action-angle variables is applied to develop a general and systematic method for calculating the influence of anharmonic perturbations on the motion of a charged particle in a Penning trap. Action-angle variables are ideally suited to determine the shifts of the characteristic frequencies in a perturbed orbit. The application of the method is demonstrated by several case studies.

And the Penning Trap
This paper begins with some background information and a summary of results in atomic supersymmetry. The connection between the supersymmetric Coulomb and os-cillator problems in arbitrary dimensions is outlined. Next, I treat the issue of finding a description of supersymmetry-based quantum-defect theory in terms of oscillators. A model with an anharmonic term that yields analytical eigenfunct...
متن کاملTheoretical basis for quantum simulation with a planar ionic crystal in a Penning trap using a triangular rotating wall
One of the challenges with quantum simulation in ion traps is that the effective spin-spin exchange couplings are not uniform across the lattice. This can be particularly important in Penning-trap realizations where the presence of an ellipsoidal boundary at the edge of the trap leads to dislocations in the crystal. By adding an additional anharmonic potential to better control interion spacing...
متن کاملDetecting Single , Trapped Ions
We have designed and constructed an experiment to trap a single ion in a Penning trap and measure its motion with an RF SQUID-based, superconducting detector. Using this apparatus we have detected the axial motion of a single, trapped N ion. We describe the theory of ion motion in an imperfect Penning trap and use this theory to explain our measurements on trapped ions. We describe and demonstr...
متن کاملNon-neutral plasma equilibria with weak axisymmetric magnetic perturbations
The effect of weak axisymmetric magnetic and/or electrostatic perturbations on the equilibrium of a non-neutral plasma in a Malmberg-Penning trap is analyzed. Analytical and semianalytical solutions for the potential variations inside the trap are found in a paraxial limit of the perturbations for various radial density profiles of the plasma, including the case of global thermal equilibrium. I...
متن کاملEUROPEAN ORGANISATION FOR NUCLEAR RESEARCH Ramsey Technique Applied in a Penning Trap Mass Spectrometer
The Ramsey method has been applied in an experiment aiming for accurate mass determination of unstable isotopes. The ion motion in a Penning trap has been excited with time-separated oscillatory elds and Ramsey fringes were observed in the case of dipole and quadrupole excitation. The experimental resonances are in good agreement with theory. Further applications of the technique are discussed....
