In every big scientific project human influence creates disorder. For an investment as big as NICA it is crucial to organize all the elements and minimize the chaos. One of the ways to achieve this goal is to create an Equipment Database (EqDb). Each component in the EqDb will receive its individual Part Identifier. Naming and Numbering Convention is a document containing instructions for Part...
We have developed and performed a Bayesian analysis for selecting the most probable equation of state under a set of constraints from compact star physics, which now include the tidal deformability from GW170817. The calculations for two-parameter family of hybrid equations of state, which produces a third family of hybrid stars in the mass-radius diagram, have been made. We are preparing to...
“The prototype dosimetry system to protect NICA Slow Control electronic equipment” project was started in Dubna at the beginning of 2018. Its primary purpose is to design a prototype dosimetry system for continuous monitoring of Multi-Purpose Detector (MPD) Slow Control electronic equipment which can protect it against accidental ionizing radiation caused by the NICA collider failure or its...
The Fast Beam-Beam Collisions (FBBC) monitor, based on the application of the secondary emission detectors – the Micro Channel Plates (MCPs), is proposed for NICA experiments at JINR. Two interaction points are foreseen for beam intersections at NICA: one for heavy-ion studies with the Multi-Purpose Detector (MPD) and another one for the polarized beams for the Spin Physics (SPD)...
Overview of the status of the front end electronics which planning to use with a long strips readout MRPC at the Time-of-Flight measurements in the NICA-MPD experiment.
The aim of the report is to present the surface characterization techniques available within the framework of the Nano-laboratory building at the FLNR, JINR. The laboratory provides state-of-the-art spectroscopy and microscopy instrumentation for research on the application of heavy-ion beams in the field of nanotechnology and materials science. The techniques available include coupled...
The paper presents the results of investigations of nuclear-physical characteristics of neutron fields generated in a massive uranium target irradiated by deuterons with an energy of 0.66 GeV. 23 natural uranium samples spatially arranged in a sub-critical assembly Quinta (at the Joint Institute for Nuclear Research, Dubna , Russia), were irradiated with spallation neutrons. We have processed...
In order to prove the existence of a critical end point (CEP) in the QCD phase diagram it is sufficient to demonstrate
that at zero temperature $T=0$ a first order phase transition exists as a function of the baryochemical potential $\mu$,
since it is established knowledge from ab-initio lattice QCD simulations that at $\mu=0$ the transition on the
temperature axis is a crossover.
We...
The Multi-Purpose Detector (MPD) being currently developed in the V&BLHEP will be used for studies of hot and dense nuclear matter, by detecting particles created in heavy ion collisions. One of the most important systems of the MPD which will be used in identification of these particles is gaseous Time-of-Flight detector, based on the mRPC (multi Resistive Plate Chambers) technology....
Information about developed interrupting system will be presented.
Hardware configuration, technology used in project, principle of operation, software creation in LabVIEW and applicability in other electronic systems will be discussed. Also positive prototype tests will be reviewed.
In order to minimize the error in the absolute position measurement by TPC, it is necessary to account for both static and time-dependent distortions in the drift path of the ionization cloud. The time-dependent distortions can result from the changes in gas performance, in environmental variables (temperature or atmospheric pressure), or from spontaneous failures. A calibration system that...
The presentation talks about the designed device,based on NiMyRio technology, which can control the motor drive using the PWM signal, based on the measurements of temperature. It presents the technological solutions used in project to get the basic functionalities and also to increase the stability of the device.
