TL;DR: In this paper, a general description of the CERN ICE electron cooling experiment is given, and the storage ring and the design and realisation of the cooling apparatus (electron gun and collector, the vacuum system, the magnetic system, beam diagnostics, high voltage stabilisation) are discussed.

TL;DR: In this paper, the ICE (initial cooling experiment) storage ring was used to cool 46 MeV protons by means of electrons in the initial cooling ring, achieving a density increase in six dimensional phase space of over a factor of 106, with cooling times in momentum spread and betatron amplitudes of 0.3 and 1.2 s, respectively.

TL;DR: In this paper, the search for an antiproton decay into an electron and a neutral pion was conducted using a stacking scheme based on stochastic cooling and an average of 7000 antiprotons were accumulated and stored in the ICE ring for 10 days.

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.
