Abstract

The core component of the silicon tracking system (STS) of the BM@N experiment at NICA is a module of CBM STS type. It consists of state-of-the-art components developed for the CBM project at FAIR: a double-sided microstrip silicon sensor, stack of low-mass micro-cables and two front-end boards (FEBs) for the readout of the P- and N-sides of the sensor. New PCB designs for the two geometries of FEBs were developed to fulfill integrational requirements of the BM@N STS project and connectivity scheme. Front-end electronics of the STS is based on STS-XYTER ASIC. Dies are installed on the PCB with a wire-bonding technology which is used due to a high density of components on the FEB. Before the module assembly all ASICs are tested and certified in a special Pogo-pin test circuit. Test algorithm for the characterization of the analog part of the STS-XYTER ASIC was developed and tested for one STS-XYTER ASIC on the FEB and will be implemented for the test bench with Pogo-pin test circuit.

Abstract

Improving the accuracy of reconstruction of the decay vertices of short-lived particles plays a fundamental role in the heavy-flavor sector of the MPD physics program. The MPD inner tracking system (ITS) based on a new generation of silicon detectors,—monolithic active pixel sensors (MAPS)—would certainly offer new possibilities within the scope of charm particle detection. A quality assessment of the MPD tracking system including ITS and time projection chamber (TPC), when reconstructing the decays of D‑mesons produced in central Au + Au collisions at $$\sqrt {{{s}_{{NN}}}} $$ = 9 GeV has been performed in the course of computer simulations in the Mpdroot framework. The selection of D-meson signals in the invariant mass spectrum of their decay products was performed using a toolkit for multivariate data analysis.

Abstract

The major upgrade of the BM@N experiment for the heavy ion program is a new hybrid tracking system. It consists of seven planes of GEM detectors and four silicon tracking stations based on the modules with double-sided microstrip silicon sensors of CBM type. The BM@N silicon tracking system (STS) will conceptually inherit the data acquisition system (DAQ) from the CBM silicon tracker currently in development for FAIR. This is an entirely data driven acquisition system relying on purely self-triggering readout channels, which will also be adopted for the operation with BM@N trigger. The core components of the readout chain are front-end boards (FEB), GBTxEmu board and GBTxEmu readout interface (GERI) board. The front-end board is an integrated part of the STS module. The main components of FEB are eight STS-XYTER ASICs which are needed for the readout of one side of the silicon sensor. The GBTxEmu board comprises an FPGA which emulates functionality of the CERN GBTx ASIC and provides a bidirectional optical link between front-end electronics and data processing boards in the computer nodes. The GERI board implements the following functionalities: concentrating and preprocessing of the data stream, filtering of the data according to the BM@N trigger signals and providing an interface for the detector control system (DCS) to configure readout electronics.

Abstract

The NICA-MPD tracking system includes the vertex silicon detector MPD-ITS designed for the efficient registration of short-lived products of nucleus–nucleus interactions. The MPD-ITS is planned to be built using the novel technology of monolithic active pixel sensors (MAPS) following the corresponding know-how transfer from CERN’s ALICE-ITS2 project to a state of capability in order to create a large-area MAPS-only tracker for its implementation at NICA. Technique-wise, the ITS is arguably the most sophisticated and ambitious project among all other detector subsystems projects of the MPD. On the other hand, the measurements of heavy flavor probes produced in central heavy ion collisions at NICA collider would be otherwise impossible. This alone is a good reason to consider it a worthwhile effort. Specifically, particles with open charm, D mesons, and the $${{\Lambda }_{c}}$$ baryon, are currently considered as one of the most perspective probes for the search of quark deconfinement in the strongly compressed fireball during its critical transition from hadronic matter to quark–gluon plasma.

Abstract

International audience; Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was created at experiments at RHIC and LHC. The transition from the QGP back to the hadron gas is found to be a smooth cross over. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure, such as a first-order phase transition between hadronic and partonic matter which terminates in a critical point, or exotic phases like quarkyonic matter. The discovery of these landmarks would be a breakthrough in our understanding of the strong interaction and is therefore in the focus of various high-energy heavy-ion research programs. The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 ( $\sqrt{s_{NN}}=$ 2.7--4.9 GeV) is to discover fundamental properties of QCD matter: the phase structure at large baryon-chemical potentials ( $\mu_B > 500$ MeV), effects of chiral symmetry, and the equation of state at high density as it is expected to occur in the core of neutron stars. In this article, we review the motivation for and the physics programme of CBM, including activities before the start of data taking in 2024, in the context of the worldwide efforts to explore high-density QCD matter.

Abstract

The MultiPurpose Detector (MPD) is designed to study heavy-ion collisions at the Nuclotron-based heavy Ion Collider fAcility (NICA) at JINR, Dubna. Its main components located inside a superconducting solenoid are a tracking system composed of a silicon microstrip vertex detector followed by a large volume time-projection chamber, a time-of-flight system for particle identification and a barrel electromagnetic calorimeter. A zero degree hadron calorimeter is designed specifically to measure the energy of spectators. In this paper, all parts of the apparatus are described and their tracking and particle identification (PID) parameters are discussed in some detail.

Abstract

The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 (√sNN = 2-4.9 GeV) is to discover fundamental properties of QCD matter, namely, the equation-of-state at high density as it is expected to occur in the core of neutron stars, effects of chiral symmetry, and the phase structure at large baryon-chemical potentials (μB ≥ 500 MeV).We are focusing here on the contribution of JINR to the CBM experiment: design of the superconducting dipole magnet; manufacture of the straw and micro-strip silicon detectors, participation in the data taking and analysis algorithms and physics program.

Abstract

Experimental ratios between the emission rates of light fragments (Li, Be, B and C) from 112,(116)Sn and 124Sn targets are compared to predictions from a model which combines the Boltzmann master equation to describe the dynamics and preequilibrium particle emission and the statistical multifragmentation model to describe the final breakup. Since secondary decay and the choice of freeze-out volume affect these ratios very little this comparison can be used to estimate the excitation energy at the instant of fragmentation in a self-consistent way. The preequilibrium nucleon emission governs the time dependence of the excitation energy available for fragment production which is nearly the same for all Sn isotopes. Therefore the yield ratios can be used to estimate the fragmentation time. Data from 1 GeV proton- and 200 MeV 4He induced reactions indicate short fragmentation times - 20-40 fm/c while 32 A MeV 14N induced reactions seems to exhibit much longer times - 300-400 fm/c.

Abstract

Predictions on ratios between the yield of light isotopes (Li, Be, B and C) from 112Sn and 124Sn nuclei from a microcanonical multifragmentation model and a sequential evaporation model are compared at excitation 175–800 MeV. Secondary decay does not affect these ratios significantly, which make them useful to estimate the excitation energy at the instant of fragmentation. The excitation energy dependence agrees well except for a local minimum near the onset of multifragmentation predicted only by the microcanonical model due to coupling between exit channels. This offers a way to distinguish between the models by measuring the relative yields of fragments from target residues differing significantly only in their neutron numbers.

Abstract

Results on isotopic effects in the production of light fragments in reactions of 14A and 32A MeV 14N ions with 112Sn and 124Sn are presented. The data are discussed in the frameworks of classical Weisskopf evaporation and an alternative Fermi gas prescription. The source isospin dependence of the production rates is consistent only with the latter prescription. It is emphasized that similar data from p-nucleus reactions and from projectile-like fragments in 40Ar induced reactions behave in the same way.

Abstract

The light output and energy resolution for the scintillators CsI(Tl), YAG(Ce), GSO(Ce), BGO and LSO(Ce) have been measured with 1H, 2H and 3He ions in the energy region ∼ 3–20 MeV/nucleon using photodiodes for the light readout. A very good energy resolution of ∼ 0.62% for 45 MeV 3He-particles has been obtained for CsI. The YAG(Ce), GSO(Ce) and LSO(Ce) crystals are non-hygroscopic, have fast decay time as main component and are well suited for experiments with high counting rates and strict timing requirements. The LSO crystal gives the best energy resolution, but reveals strong quenching for heavy ions. The GSO crystal is a good candidate for operation in UHV environment and has high stopping power, short decay time (56 ns) and moderate quenching.

Abstract

Neutron-proton correlation functions in 30A MeV 40 Ar + 197 Au , 12 C , CH 2 reactions have been measured. In contrast to the nn and pp correlations, which exhibit the shape expected from quantum symmetrization effects and nuclear+Coulomb (pp) final-state interaction, the np function shows much less correlation strength. This may be due to Coulomb repulsion on the proton and/or to a larger effective spin than expected. Selecting high energy nucleons strengthens both the np and pp correlations.

Abstract

An experimental study of nuclear reactions between Si-28 nuclei at 200 and 300 MeV/nucleon and hydrogen or deuterium target nuclei was performed at the CELSIUS storage ring in Uppsala, Sweden, to collect information about the reactions responsible for single-event effects in microelectronics. Inclusive data on Si-28 fragmentation, as well as data on correlations between recoils and spectator protons or alpha particles are compared to predictions from the Dubna cascade model and the Japan Atomic Energy Research Institute version of the quantum molecular dynamics model. The comparison shows satisfactory agreement for inclusive data except for He fragments where low-energy sub-barrier fragments and recoiling fragments with very large momenta are produced much more frequently than predicted. The yield of exclusive data are also severely underestimated by the models whereas the charge distributions of recoils in these correlations compare well. The observed enhancement in He emission, which may well be important for the description of single-event effects, is most likely to be attributed to alpha clustering in Si-28 nuclei.

The lack of systematic experimental checks on the intermediate‐energy nuclear model simulations of heavily ionizing recoils from nucleon‐nucleus collisions — critical inputs for the Single Event Effect analysis of microelectronics and dosimetry calculations including high‐LET components in the cancer tumor radiation therapy — has been a primary motivation for a new experiment planned at the CELSIUS nuclear storage ring of The Svedberg Laboratory, Uppsala, Sweden. Details of the experiment and the first results from a feasibility study are presented here.

Abstract

The relative yields of high energy deuterons and tritons as compared to protons have been measured in $p+\mathrm{Kr},$ ${}^{16}\mathrm{O}+\mathrm{Kr}$ and ${}^{20}\mathrm{Ne}+\mathrm{Ar}$ reactions with a continuously varying beam energy up to $500A(400A) \mathrm{MeV}.$ Statistical (expanding) evaporation models are not able to reproduce these $d/p$ or $t/p$ ratios, which for high particle energy $(g30 \mathrm{MeV})$ increase smoothly with beam energy. Models that contain nucleon-nucleon scattering, like cascade or nuclear molecular dynamics models, can only reproduce the ratios if a final-state interaction is introduced via the coalescence prescription. The coalescence radius that best fit the data is rather constant over wide beam energy intervals. Entropy can, however, not be directly determined from these ratios.

Abstract

The emission of light fragments with energies \ensuremath{\ge}1A MeV from asymmetric $^{14}\mathrm{N}$ induced reactions at 14A MeV and 32A MeV has been studied. The overall energy- and angular dependence of the isobaric $^{3}\mathrm{H}$${/}^{3}$He and $^{6}\mathrm{He}$${/}^{6}$Li ratios is understood in terms of standard statistical emission processes from an incomplete fusion source and an intermediate source only if the effective Coulomb barriers are reduced much more than the normal quantum penetration accounts for.

Abstract

Inclusive cross sections for the emission of 3H, 3He and 4He at laboratory angles of 45°, 90° and 135° in collisions of 4He with targets of 9Be, 12C, 27Al, 64Cu, 108Ag and 197Au at a beam kinetic energy of 3.33 GeV/nucleon are presented. Assuming the existence of an intermediate object emitting fragments, we have found its velocity and temperature for different fragment energies. It is shown that the velocity and temperature continuously increase with the fragment energy under consideration. The evaporation mechanism is discussed, and it is argued that the evaporation significantly contributes to the yield of fragments with energy less than 50 MeV. The considered 3H to 3He ratio is found to be larger than the neutron to proton ratio in the emitting system. Comparing 3H and 3He spectra, an important role of the Coulomb barrier is shown. The At dependence of the yield of the fragments is studied. The experimental spectra are compared with thermodynamic firestreak model predictions. The model is successful in describing the emission of fragments with energy greater than 50 MeV.

Abstract

The use of storage rings, operating in slow ramping mode to obtain excitation function data, is presented. Such experiments could provide a new way of probing the liquid-gas phase transition. We also discuss “isotopic effect ratios” which may act both as thermometer and as clock for the fragmentation process. Recent data on π + , p and d emission in the first slow ramping experiments at the CELSIUS storage ring are presented.
