Ion dynamics in a linear radio-frequency trap with a single cooling laser
We analyse the possibility of cooling ions with a single laser beam, due to the coupling between the three components of their motion induced by the Coulomb interaction. For this purpose, we numerically study the dynamics of ion clouds of up to 140 particles, trapped in a linear quadrupole potential and cooled with a laser beam propagating in the radial plane. We use Molecular Dynamics simulati...
متن کاملLaser-cooling of Ions and Ion Acceleration in the RF-Quadrupole Ring Trap PALLAS
We report on the commissioning of the table-top RF-Quadrupole storage ring PALLAS , dedicated to the experimental realization of crystalline ion beams. Images of large prolate 24Mg+-ion crystals are presented, operating PALLAS locally as a linear rf-trap and applying laser-cooling, beautifully confirming prior theoretical and experimental work. For few-ion strings, a radial oscillation of the c...

متن کاملSimultaneous cooling of axial vibrational modes in a linear ion-trap
In order to use a collection of trapped ions for experiments where a well defined preparation of vibrational states is necessary, all vibrational modes have to be cooled to ensure precise and repeatable manipulation of the ions’ quantum states. A method for simultaneous sideband cooling of all axial vibrational modes is proposed. By application of a magnetic field gradient the absorption spectr...
متن کاملParametric excitations of trapped ions in a linear rf ion trap
The parametric resonant behavior of ions inside a linear rf ion trap is studied both theoretically and experimentally. Theoretically, the resonant motion of ions inside an ideal ion trap is described by approximating the trapping rf field as a harmonic pseudopotential with the ions being excited by an additional quadrupolar ac voltage. The resulting damped Mathieu equation is studied and the re...
