Applications of laser cooled ions in a Penning trap

Abstract

This paper aims to describe in basic terms how the different types of ion traps work, giving some examples of their use. It then discusses some recent 'exotic' designs of ion traps and shows how they are optimized for particular experiments. Recent work at Imperial College London is used to illustrate some of the ideas introduced in this paper.

Spectroscopy of Laser-cooled Ions

Richard Claude Thompson, Kishan Dholakia, G. Horváth +2 more

This paper is a written version of an invited review talk given at the 11th National Quantum Electronics Conference in Belfast in September 1993. It discusses the use of trapped ions for spectroscopy in both the optical and microwave regions of the spectrum. After introductory comments on the advantages offered by ion traps and laser cooling for spectroscopy, we take the the example of spectroscopy of mercury ions to show how many different types of experiment can be performed, with striking results. We also discuss our recent work at Imperial College, which can be seen as spectroscopy of the ion trap itself, giving information on the dynamics of the trapped ions.

Laser Cooling of Magnesium Ions Confined in a Penning Trap

Richard Claude Thompson, G. P. Barwood, Patrick Robert Gill

The construction of a Penning ion trap is described. The trap has been used to confine clouds of magnesium ions for periods of many hours and the ions have been cooled to sub-kelvin temperatures by the method of laser cooling. Preliminary experiments with the cooled ions are reported.

Laser-cooled trapped-ion experiments at NIST

We describe some recent experiments that use a new Penning trap to trap and laser‐cool more than 105 Be+ ions. In this wrok the Coulomb coupling parameter was estimated to by typically greter than 100 and in some cases greater than 300. Shell structure was difficult to observe in the ion fluorescence from these large clouds. An initial Bragg scattering experiment to obtain information on the ion correlations is described. We also briefly review our work on the electrostatic modes of a Penning trap plasma including the use fo the modes to diagnose the shape and density of a cryogenic electron plasma. Some applications of laser‐cooled plasmas in Penning traps, such as atomic clocks, are discussed.

Laser cooling of trapped ions

Jürgen Eschner, Giovanna Morigi, Ferdinand Schmidt‐Kaler +1 more

Trapped and laser-cooled ions are increasingly used for a variety of modern high-precision experiments, for frequency standard applications, and for quantum information processing. Therefore laser cooling of trapped ions is reviewed, the current state of the art is reported, and several new cooling techniques are outlined. The principles of ion trapping and the basic concepts of laser cooling for trapped atoms are introduced. The underlying physical mechanisms are presented, and basic experiments are briefly sketched. Particular attention is paid to recent progress by elucidating several milestone experiments. In addition, a number of special cooling techniques pertaining to trapped ions are reviewed; open questions and future research lines are indicated.

Ion Trap. Recent Experiments.

Makoto Sakuai, Masahiro Kimura, Shunsuke Ohtani

Recent experimental works with ion traps are surveyed.Ion traps can confine ions of very low-energy in a small space, and they are useful tools for the precise spectroscopy of ions.Basic ideas on trapping mechanism of several types of the traps and detection methods of trapped ions are summarized.Major topics are ultrahigh-resolution spectroscopy of ions using laser cooling methods and physics on one-component plasmas such as localization, phase transition and crystallization of ion cloud.Applications to elementary particle physics , nuclear physics and atomic physics on multiply charged ions are also presented.
