- ПубликацияТолько метаданныеThe Detector Development and Physics Program in sPHENIX Experiment at RHIC(2019) Kim, Y.; Angerami, A.; Alfred, M.; Atkin, E.; Brandin, A.; Okorokov, V.; Riabov, V.; Samsonov, V.; Strikhanov, M.; Taranenko, A.; Аткин, Эдуард Викторович; Брандин, Андрей Владимирович; Окороков, Виталий Алексеевич; Рябов, Виктор Германович; Стриханов, Михаил Николаевич; Тараненко, Аркадий ВладимировичThe sPHENIX experiment at RHIC will collect high statistics proton-proton, proton-nucleus and nucleus-nucleus data, starting in the early 2020's. The sPHENIX capabilities enable state-of-the-art studies of jet modification, upsilon suppression and open heavy flavor production to probe the microscopic nature of the strongly-coupled Quark Gluon Plasma, and will allow a broad range of cold QCD studies. The sPHENIX detector will provide precision vertexing, tracking and electromagnetic and hadronic calorimetry in the central pseudorapidity region vertical bar eta vertical bar < 1.1, with full azimuth coverage, at the full RHIC collision rate, delivering unprecedented data sets for hard probe tomography measurements at RHIC. In this talk, we will present a brief overview of the sPHENIX detector design with emphasis on calorimetry. The novel design of the sPHENIX calorimeters includes a tungsten/scintillating fiber electromagnetic calorimeter and two steel/scintillating tile hadronic calorimeter sections. The calorimeter has been optimized for upsilon and jet measurements in the high multiplicity environment of heavy-ion collisions. The design has been simulated in detail using GEANT4, and the simulations have extensively vetted against results obtained from the T-1044 test beam facility at FNAL Both simulation data and test beam data, and the resulting jet physics performance, will be presented in this talk.

In this context, the existence of weakly interacting massive particles represents an appealing solution to the observed thermal relic in the Universe. Indeed, a large experimental campaign is ongoing for the detection of such particles in the sub-GeV mass range. Adopting the benchmark scenario for light dark matter particles produced in the decay of a dark photon, with αD = 0.1 and mA′ = 3mχ, we study the potential of the SHiP experiment to detect such elusive particles through its Scattering and Neutrino detector (SND). In its 5-years run, corresponding to 2 · 1020 protons on target from the CERN SPS, we find that SHiP will improve the current limits in the mass range for the dark matter from about 1 MeV to 300 MeV. In particular, we show that SHiP will probe the thermal target for Majorana candidates in most of this mass window and even reach the Pseudo-Dirac thermal relic. [Figure not available: see fulltext.]
- ПубликацияТолько метаданныеDevelopment of Data Concentration Method and Its Implementation in a Radiation-Tolerant CMOS Application Specific Integrated Circuit(2021) Atkin, E.; Azarov, D.; Normanov, D.; Ivanov, P.; Samsonov, V.; Serazetdinov, A.; Shumikhin, V.; Аткин, Эдуард Викторович; Норманов, Дмитрий Дмитриевич; Серазетдинов, Артур Рафикович© 2021, Pleiades Publishing, Ltd.Abstract: The results of the concentration method development for the data coming from the detector integrated circuits, intended for the experimental facilities MPD and BM@N, are presented. Charged particle detectors at these installations are characterized by a high granularity and accuracy of the detecting equipment. That results in a large data volume and the need to transfer processed data at a gigabit rate. Therefore, ASIC of the data concentrator requires both a high integration and use of specific structure as well as circuit and layout to provide an increased radiation tolerance. A specific feature of the ASIC is its ability to operate in the actual radiation background of the experiments estimated by up to 100 kRad in terms of immunity to heavy charged particles. In order to approbate the method and solutions on improvement of the radiation tolerance, the design results of a prototype 65 nm CMOS ASIC for read-out the signals from two SAMPA front-end chips cards are described. ASIC is intended for data receipt, concentration and subsequent transmission at a rate of 2.56 Gbit/s over micro-coaxial cables of 1 m length.
- ПубликацияТолько метаданныеUnperturbed inverse kinematics nucleon knockout measurements with a carbon beam(2021) Patsyuk, M.; Kahlbow, J.; Laskaris, G.; Duer, M.; Atkin, E.; Barbashina, N.; Bolozdynya, A.; Fillipov, K.; Finogeev, D.; Galavanov, A.; Morozov, S.; Samsonov, V.; Selyuzhenkov, I.; Senger, P.; Shumikhin, V.; Sosnovtsev, V.; Strikhanov, M.; Taranenko, A.; Аткин, Эдуард Викторович; Барбашина, Наталья Сергеевна; Болоздыня, Александр Иванович; Галаванов, Андрей Владиевич; Сосновцев, Валерий Витальевич; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович© 2021, The Author(s), under exclusive licence to Springer Nature Limited part of Springer Nature.Particle knockout scattering experiments1,2 are fundamental for mapping the structure of atomic nuclei2–6, but their interpretation is often complicated by initial- and final-state interactions of the incoming and scattered particles1,2,7–9. Such interactions lead to reduction in the scattered particle flux and distort their kinematics. Here we overcome this limitation by measuring the quasi-free scattering of 48 GeV c–112C ions from hydrogen. The distribution of single protons is studied by detecting two protons at large angles in coincidence with an intact 11B nucleus. The 11B detection suppresses the otherwise large distortions of reconstructed single-proton distributions induced by initial- and final-state interactions. By further detecting residual 10B and 10Be nuclei, we also identified short-range correlated nucleon–nucleon pairs9–13 and provide direct experimental evidence for separation of the pair wavefunction from that of the residual many-body nuclear system9,14. All measured reactions are well described by theoretical calculations that include no distortions from the initial- and final-state interactions. Our results showcase the ability to study the short-distance structure of short-lived radioactive nuclei at the forthcoming Facility for Antiproton and Ion Research (FAIR)15 and Facility for Rare Isotope Beams (FRIB)16 facilities, which is relevant for understanding the structure and properties of nuclei far from stability and the formation of visible matter in the Universe.
- ПубликацияТолько метаданныеImplementation of Interpolation in Read-out ASIC for GEM Detectors(2021) Shumikhin, V. V.; Atkin, E. V.; Azarov, D. A.; Ivanov, P. Y.; Normanov, D. D.; Аткин, Эдуард Викторович; Норманов, Дмитрий Дмитриевич© 2021, Pleiades Publishing, Ltd.Abstract: The results of designing a readout ASIC for GEM detectors are presented. The chip has a built-in digital signal processing system intended to calculate the maximum signal amplitude (input charge) and based on the principle of interpolation. Using interpolation allowed to calculate the maximum charge amplitude with an accuracy of 1.5 LSB at using a built-in 10-bit ADC having a maximum conversion frequency of 25 MHz and a shaping amplifier with a peaking time of 320 ns. The readout ASIC was designed in UMC MMRF 180 nm CMOS process.
- ПубликацияТолько метаданныеFast simulation of muons produced at the SHiP experiment using Generative Adversarial Networks(2019) Ahdida, C.; Albanese, R.

The SHiP experiment will be able to search for new long-lived particles produced in a 400 GeV/c SPS proton beam dump and which travel distances between fifty metres and tens of kilometers. The SHiP detector needs to operate under ultra-low background conditions and requires large simulated samples of muon induced background processes. Through the use of Generative Adversarial Networks it is possible to emulate the simulation of the interaction of 400 GeV/c proton beams with the SHiP target, an otherwise computationally intensive process. For the simulation requirements of the SHiP experiment, generative networks are capable of approximating the full simulation of the dense fixed target, offering a speed increase by a factor of (106). To evaluate the performance of such an approach, comparisons of the distributions of reconstructed muon momenta in SHiP's spectrometer between samples using the full simulation and samples produced through generative models are presented. The methods discussed in this paper can be generalised and applied to modelling any non-discrete multi-dimensional distribution.
