An electron beam ion trap has been built for the production of very-highly-charged ions and the study of their collisions with electrons. A high density electron beam is used to trap, ionize and excite the ions for spectroscopic measurements. X-ray spectra from neon-like Ba46+ are reported and a theory of "evaporative" cooling is developed to explain why these ions are retained in the trap for surprisingly long times.read more

High-accuracy mass spectrometry with stored ions
TL;DR: The mass of an atom, and its inherent connection with the atomic and nuclear binding energy is a fundamental property, a unique fingerprint of the atomic nucleus as mentioned in this paper, and the importance of its mass ranges from verification of nuclear models to a test of the Standard Model, in particular with regard to the weak interaction and the unitarity of the Cabibbo-Kobayashi-Maskawa quark mixing matrix.

A trapped single ion inside a Bose-Einstein condensate.
TL;DR: This work investigates whether atomic quantum gases and single trapped ions can be advantageously combined into one hybrid system, by exploring the immersion of a single trapped ion into a Bose–Einstein condensate of neutral atoms.

Highly charged ions: Optical clocks and applications in fundamental physics
TL;DR: In this article, a review discusses how a variety of ion species and transitions may optimally be used to target new applications, and presents routes to handle them in the laboratory, as well as how to handle ion species for precision spectroscopy and accurate clocks.

Optical Theory of Thermal Velocity Effects in Cylindrical Electron Beams
TL;DR: In this article, a non-laminar optical model is proposed to calculate trajectories at any point in a long high-density electron beam, where thermal velocities are treated as an integral part of the motion.

Miniature high current metal ion source
TL;DR: In this article, a simple ion source for the production of high brightness beams of metal ions is described, and a metal vapor vacuum arc discharge is used to establish the high density plasma from which the ion beam is extracted.
