“…It will offer the unique opportunity to scatter electrons with an energy of up to 0.5 GeV off short-lived exotic nuclei with energies up to 0.74 GeV/nucleon [399,400], in order to investigate the structure of radioactive isotopes. Figure 17 presents the schematic layout of the New Experimental Storage Ring (NESR, circumference 222.9 m) [401] for Rare Isotope Beams (RIB) and the Electron Antiproton Ring (EAR, circumference 53.7 m, selected such that the revolution frequency of the EAR is 5 times that of one of the ions). Electrons with energies ranging from 125 to 500 MeV will be provided by an electron linac and stored in the EAR.…”

Received X XXXXX XXXX Revised XX XXXXX XXXX Nuclear masses are the most fundamental of all nuclear properties, yet they can provide a wealth of knowledge, including information on astrophysical sites, constraints on existing theory, and fundamental symmetries. In nearly all applications, it is necessary to measure nuclear masses with very high precision. As mass measurements push to more short-lived and more massive nuclei, the practical constraints on mass measurement techniques become more exacting. Various techniques used to measure nuclear masses, including their advantages and disadvantages are described. Descriptions of some of the world facilities at which the nuclear mass measurements are performed are given, and brief summaries of planned facilities are presented. Future directions are mentioned, and conclusions are presented which provide a possible outlook and emphasis on upcoming plans for nuclear mass measurements at existing facilities, those under construction, and those being planned.

“…We have derived growth rates of root mean square (rms) beam emittance and rms momentum spread by simulating the evolution of the ion distribution function with time, using the BETACOOL code to study the long-term beam dynamics in storage rings [26,27]. Initially developed by JINR scientists in collaboration with leading scientific centers worldwide to estimate heating and cooling effects in high-energy storage rings with electron cooling, BETACOOL has been successfully benchmarked at different accelerator labs worldwide [28][29][30][31][32][33][34][35][36][37]. The software is under continual development and new physics models in the lowenergy range were implemented for our particular studies.…”

Electrostatic storage rings operate at very low energies in the keV range and have proven to be invaluable tools for atomic and molecular physics. Because of the mass independence of electric rigidity, these machines are able to store a wide range of different particles, from light ions to heavy singly charged biomolecules, opening up unique research opportunities. However, earlier measurements have shown strong limitations in maximum beam intensity, fast decay of the stored ion current, and reduced beam lifetime. The nature of these effects has not been fully understood and an improved understanding of the physical processes influencing beam motion and stability in such rings is needed. In this paper, a comprehensive study into nonlinear and long-term beam dynamics studies is presented on the examples of a number of existing and planned electrostatic storage rings using the BETACOOL, OPERA-3D, and MAD-X simulation software. A detailed investigation into ion kinetics, under consideration of effects from electron cooling and multiple scattering of the beam on a supersonic gas jet target, is carried out and yields a consistent explanation of the physical effects in a whole class of storage rings. The lifetime, equilibrium momentum spread, and equilibrium lateral spread during collisions with the target are estimated. In addition, the results from experiments at the Test Storage Ring, where a low-intensity beam of CF þ ions at 93 keV=u has been shrunk to extremely small dimensions, are reproduced. Based on these simulations, the conditions for stable ring operation with an extremely low-emittance beam are presented. Finally, results from studies into the interaction of 3-30 keV ions with a gas jet target are summarized.
