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.

TL;DR: In this paper, the electron-ion capture rate for low electron energies is calculated for various electron velocity distributions and the results are applied to electron cooling and to positron-antiproton recombination to form antihydrogen.
Abstract: The electron-ion capture rate for low electron energies is calculated for various electron velocity distributions. Capture rates for electron-ion recombination stimulated by irradiation with light are evaluated. The results are applied to electron cooling and to positron-antiproton recombination to form antihydrogen. It is shown that laser-induced capture is a powerful method to study the electron cooling process and to maximize the antihydrogen rate. With this technique a pulsed antihydrogen beam of selectable energy and well collimated with an intensity of a few atoms per second can be anticipated.

TL;DR: In this article, the physical, engineering, and economic feasibility of antiproton annihilation propulsion was investigated. And the conclusion of the study is that it is feasible, but expensive.
Abstract: : Antiproton annihilation propulsion is a new form of space propulsion, where milligrams of antimatter are used to heat tons of reaction fluid to high temperatures. The hot reaction fluid is exhausted from a nozzle to produce high thrust at high specific impulse. This study was to determine the physical, engineering, and economic feasibility of antiproton annihilation propulsion. The conclusion of the study is that antiproton propulsion is feasible, but expensive. Because the low mass of the antimatter fuel more than compensates for its high price, comparative mission studies show that antimatter fuel can be cost effective in space, where even normal chemical fuel is expensive because its mass must be lifted into orbit before it can be used. Antiproton annihilation propulsion is mission enabling, in that it allows missions to be performed that cannot be performed by any other propulsion system. Keywords: Antimatter propulsion; Antiproton; Advanced propulsion.

TL;DR: In this article, a monitoring device for the transverse density distribution of stored heavy-ion beams, based on the detection of ionization products of the beam particles in the residual gas, has been developed for the heavy ion Test Storage Ring (TSR) in Heidelberg.
Abstract: A monitoring device for the transverse density distribution of stored heavy-ion beams, based on the detection of ionization products of the beam particles in the residual gas, has been developed for the heavy-ion Test Storage Ring (TSR) in Heidelberg. With two monitor units installed in the ring, non-destructive, sensitive measurements of the horizontal and vertical profiles of cooled stored ion beams can be performed with a spatial resolution of about ±(0.2–0.3) mm. The beam profile monitors are used to determine the transverse beam temperature, to study transverse cooling and heating mechanisms, to observe the ion beam behaviour during experiments, and to determine storage-ring parameters such as the dispersion function. The principle, technical realization and operation of these devices are described. First experimental results concerning transverse electron cooling of heavy-ion beams are discussed, in particular the measurement of cooling rates and the optimization of the alignment between the stored ion beam and the cooling electron beam.

TL;DR: In this article, the authors present an overview of the current advances in the rapidly developing field of heavy ion accelerator technology and discuss the fundamental physics of the heavy ion collisions and atomic structure.
Abstract: Publisher Summary This chapter presents an overview of the current advances in the rapidly developing field of heavy ion accelerator technology Now, essential aspects in this area are accessible In the meantime, great progress already has been made in the fundamental physics in this field This is particularly true for achievements in the atomic physics of highly charged heavy ions There are two general domains to be considered in the atomic physics of highly charged heavy ions: the fields of collisions and of atomic structure Both aspects have to be explored equally because they are strongly interconnected The interaction processes has to be investigated to know, for instance, the population of excited states to help answer questions on the atomic structure; conversely, the structure has to be known to understand the interactions In both the fields, fundamental principles can be studied uniquely This is in particular true for the heaviest ion species with only a few- or even zero-electrons left
