“…where ϕ m is the potential created by the m-th atom of the target; m = 1, 2, ..., N , here N is the number of atoms in the target. In the rest frame of the ion (7) the potential turns out to be dependent on the time and impacts the ion electrons during some period 1 − v 2 /c 2 L/c (where L is the characteristic size of the target). Let us assume that this time is significantly shorter than the characteristic periods of time for the ion electrons.…”

“…In contrast, when working with solid targets, one is able to simply choose the target with the best properties for stripping. There is a current requirement for the maximum stripping of a structured heavy ion for experiments with quark-gluon plasma and for other heavy-ion accelerators, for example, for the NICA Project (Dubna, Russia) [7], RHIC (USA), GSI (Darmstadt, Germany) and LHC (Switzerland, France). Structured heavy-ion stripping is more significant at v >> 1, where v is the ion velocity in atomic units (used from here on)).…”

The search is now on for, new materials that can be used for ionic stripping. Materials that maximize the stripping of the structural ion are important for conducting experiments with quark-gluon plasma. Although this paper is a theoretical study, it offers practical application, in heavy-ion accelerators, of the new effect of collision multiplicity with high-energy ions interacting with polyatomic targets. It is shown that internal nanostructured targets in which the collision multiplicity effect is manifested can more efficiently strip out structural ions compared to standard internal targets for stripping. A target consisting of oriented nano-tubes with the C240 chirality (10,0) is considered as an example. A comparison with the stripping process on a carbon target with the same number of misaligned atoms in a unit of volume C is provided.

“…The SPD project at NICA aims primarily at polarization experiments in the collider mode. In the broader context, the main virtue of NICA facility is high current beams of polarized protons and deuterons [392,393]. We report here new ideas developed in the framework of the Russian Fund for Basic Research Grant No.…”

Nuclotron based Ion Collider fAcility (NICA) project is in progress at the Joint Institute for Nuclear Research and will start experiments with heavy ions. In the context of the NICA Hadronic Physics programme double polarized pp-, dd-and pd-collisions even at lower energies of √ sNN = 3.4 − 10 GeV, which will be accessible already at the initial stage of experiments,are essential tools for precise understanding the spin dependence of the nucleon-nucleon strong interactions, in both elastic and deep-inelastic regimes. A special interest is interaction in few baryon systems at double strangeness, charm and beauty thresholds.For instance, polarized large-angle elastic pp and pn scattering near the charm threshold allows one to get an access to properties of possible exotic multiquark states and their relation to the states recently observed at LHCb.Large angle scattering of protons and deuterons on the deuteron contains unique information on the short-range structure of the deuteron, its non-nucleonic degrees of freedom and also on color transparency phenomenon. Furthermore, double polarized proton-deuteron scattering offer a possibility to test the Standard Model through the search for time-invariance (or CP-invariance under CPT symmetry) violation and parity-violation in single-polarized scattering. This paper contains suggestions for experiments with usage of the Spin Physics Detector (SPD) and discusses perspectives of the first stage of the SPD Programme. This includes experiments with non-polarized beams too as well as collisions like 12 С-12 С and 40 Сa-40 Ca.9 Multiquark correlations and exotic hadron state production 9 9.1 Multiquark correlations and exotic state production at SPD NICA . . . .

The historical development of techniques for cooling charged particles is presented. It was G I Budker, the founder and first Director of the Institute of Nuclear Physics (INP) in Novosibirsk, who initiated the development of cooling methods as a means of improving the performance of colliding beams accelerators (now known as colliders). The electron cooling method proposed by G I Budker became the main subject of investigation at BINP. Today, many facilities — ranging from the LHC to those on a moderate university scale — use the electron cooling of heavy ions in nuclear and atomic physics experiments with highly charged ions. The stochastic cooling method proposed by van der Meer has become the primary tool for accumulating and cooling antiprotons.
