A new experiment is described to detect a permanent electric dipole moment of the proton with sensitivity $10^{-29}e\cdot$cm by using polarized "magic" momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant are discussed and techniques address them presented. The measurement sensitive physics beyond Standard Model at scale 3000~TeV.

In distinction to popular tungsten foil, here solid neon used as moderator. It allows obtain intensity about 10 5 e + /s width spectrum characterized by full...
Zr/Nb nanoscale multilayer coatings (NMCs) were studied after hydrogenation in a gaseous environment at 400 °C. The hydrogen distribution and content determined by pressure time. Increasing the from 0.2 to 2 MPa resulted different within NMCs, while concentration remained constant 0.0150 ± 0.0015 wt. %. increased 0.0165 0.001 0.0370 % when time was extended 1 7 h. δ-ZrH hydride phase formed Zr layers with crystals reorienting towards [100] direction.

The “Nuclotron-M” project started in 2007 is considered as the key point of first stage NICA/MPD project. General goal to prepare all systems Nuclotron for its long and reliable operation a part NICA collider injection chain. Additionally realization will increase ability current experimental program. Results last runs are presented.
The effect of helium ion irradiation on the microstructure and properties composites based Zr/Nb nanoscale multilayer coatings (NMCs) was studied. X-ray diffraction (XRD), transmission electron microscopy (TEM), variable-energy Doppler broadening spectroscopy (DBS) were used for in-depth analysis defects in irradiated NMCs. After NMCs with ions at a 1017 ion/cm2 dose, layered structure generally retained, but internal stresses layers increased, which caused wave-like distortion deposition...
High-energy electron cooling can open new possibilities in particle physics by producing high-quality hadron beams colliders, and is presently considered for several accelerator projects. However, it also presents many unique features challenges. For example, an accurate estimate of the times requires a detailed calculation process, which takes place simultaneously with various diffusive mechanisms. This task becomes even more challenging when performed directly at collision energy puts...

Fundamental advances in experimental nuclear physics will require ion beams with orders of magnitude luminosity increase and temperature reduction. One the most promising particle accelerator techniques for achieving these goals is electron cooling, where beam repeatedly transfers thermal energy to a copropagating beam. The dynamical friction force on fully ionized gold moving through magnetized unmagnetized distributions has been simulated, using molecular dynamics that resolve close binary...
High-energy electron cooling, presently considered as an essential tool for several applications in high-energy and nuclear physics, requires accurate description of the friction force which ions experience by passing through beam.
