Electron cooling system for the NICA project requires a high homogeneity of the magnetic field in order to obtain the required cooling efficiency. High temperature superconducting open-type shielding could decrease the costs of such system (compared to the conventional high precision solenoid windings). Shielding effect of HTS tape was tested. The experiments were conducted in JINR, Russia, in...

At present, the accelerator complex NICA [1] is being built at JINR (Dubna). It is intended for performing experiments to study interactions of relativistic nuclei and polarized particles (protons and deuterons). One of the experimental facilities MPD (MultiPurpose Detector) [2] was designed to investigate nucleus-nucleus, proton-nucleus and proton-proton interactions.
As one of the...

A series of experiments on the elastic scattering of 15N ions from 10,11B has been done at U-200P cyclotron at Heavy Ion Laboratory, Warsaw University using the charged particles detection system ICARE. The measured differential distributions are used for obtaining the theoretical interpretation in terms of the Optical Model for pure elastic scattering and Distorted wave Born Approximation for...

In the current study, the model of Passive Heat Removal System (PHRS) through SG (steam-generator) was developed for computational fluid dynamics (CFD) analysis. Passive Heat Removal System is a protective safety system of Nuclear Power Plant based on the principle of a passive action, designed to provide long-term heat removal from the reactor core via secondary circuit. A thorough...

The detailed simulation of electron drifting in the MPD TPC was made with CERN Garfield toolkit for the simulation of gas particle detectors. For electron transporting were used the Ar+CH4 gas mixture with impact of magnetic and electric fields. Ionization processes were investigated in the wire planes area near readout chambers of the TPC.

The φ0-Josephson junction model with direct coupling between magnetic moment and Josephson current is considered. In this framework, effect of the full magnetization reversal is numerically studied in the wide range of parameters of the model. The simulation is based on the implicit two-stage Gauss-Legendre algorithm of the 4th accuracy order. Effect of parallel execution of respective C++...

The paper considers the problem of optimiziation of the heat source characteristics of the cryogenic cell -- a multi-layer cylindrical configuration of the sandwich type, intended for pulse dosed injection of the working gaseous spicies in to the ionization chamber of the multiply charged ion source. For solving the optimization problem, a hybrid MPI+OpenMP parallel computation algorithm based...

Terrestrial gamma flash (TGF) and thunderstorm ground enhancements(TGE) phenomena are crucial for understanding of atmosphere breakdown and lightning generation physics. The initial theory was developed by Gurevich and included only runway breakdown description. It was later updated by Babich and Dwayer, but even updated model uses a rather simplified field structure and does not fully match...
