We would like to present the results of the comparison of two different types of readout and data acquisition systems (DAQ) through the example of CBM RICH DAQ. Two triggerless DAQ systems are characterized โ one based on nXYTER chip and SysCore readout controller and second based on PADIWA front-end board and multi-functional TRB board. Measurement of time characteristics in laboratory and...

We present the wave propagator determination and improved phase retrieval algorithm invented specifically for imaging of biological objects using Bragg Magnifier Microscope (BMM). The robustness of the algorithm is tested on different samples and the results are shown. First, it is applied to the experimentally measured diffractograms of well-defined samples of polystyrene spheres and siemens...

In the present work, the theoretical analysis of deep inelastic collisions (DIC) with heavy ions is performed based on the dynamical model of ion-ion collisions. Studying of this type of nuclear reactions allows one to extract the information about complex interaction of heavy ions with each other leading to the significant dissipation of the initial kinetic energy and the exchange of a large...

The direct bond percolation process is studied in the presence of random velocity fluctuations. Using Doi approach a coarse grained field-theoretic action is obtained which captures universal
properties of the model near its second order phase transition. Velocity field is modeled by the stochastic Gaussian field with finite correlation time and compressibility taken into account.

The model of a two-dimensional (2D) hydrogen atom in external electric field is investigated.
Due to the anisotropy of the influenced interaction the partial wave analysis is ineffective. The algorithm for the numerical solution of the 2D time-dependent Schroedinger equation with anisotropic interaction is proposed. The good convergence and advantages of the algorithm are presented. The good...

I present a study of U(1) gauged modification of the 2+1 dimensional planar Skyrme model with a particular choice of the symmetry breaking potential term which combines a short-range repulsion and a long-range attraction. In the absence of the gauge interaction the multi-solitons of the model are aloof, they consist of the individual constituents which are well separated. Peculiar feature of...

It is assumed that Parker instability leads to the formation of the flux tubes of the toroidal magnetic field in regions of the effective generation of the magnetic field. We modify our magneto-gas-dynamic model of accretion disks [1] in order to take into account buoyancy of the toroidal magnetic field. Stationary...

Based on the magnetic symmetry structure of non-Abelian gauge theories, a dual QCD gauge theory is constructed which takes into account the local structure as well as the topological structure of the color gauge group into its dynamics and contains two potentials, the electric and the magnetic potentials in a dual-symmetric way. Using the dual version of QCD in thermal domain following the...

Preliminary alpha capture cross sections on p-nuclei at energies close to the Gamow window will be presented. The cross section were measured by means of the activation method using an alpha beam delivered by the IFIN-HH tandem accelerator. The induced activities were measured in close-to-detection geometry using two large volume HPGe detectors in a low background passive shielding.

To achieve low background in rare events physics experiments, several techniques are used. Apart from external veto and shielding, one can recognize the physical process taking place in the detector by analyzing the pulse shape of the detector signal. A presented discrimination method between multi-site and single-site energy deposition events in High Purity Germanium detectors is performed on...

In this paper the experimental results and simulation results of the production of the exotic 6He nuclei with the use of the 22 MeV electron beam provided by the MT-25 microtron are presented.
This method for obtaining 6 He nuclei may turn out to be one of the most optimal and inexpensive as compared with other methods, which are used for the production of exotic nuclei.

Biomineralization is a process in which living organisms form minerals from organic and inorganic components. By its mechanical properties biominerals surpass minerals that spontaneously form without presence of organic molecules.

In the plan of the modernization IBR-2 reactor around a reactor core will be installed 3 cryogenic neutron moderators. For slowdown neutrons in moderators use a mesitylene with m-xylene as frozen beads with a diameter of 3-4 mm. These pellets are served in a moderator chamber by a helium flow. Currently, one of the moderators (202) is already installed and working on the experiment.
