Measurements of hadron production in the TeV energy range are one of the tasks of the future studies at the Large Hadron Collider (LHC). The main goal of these experiments is a study of the ...fundamental QCD processes at this energy range, which is very important not only for probing of the Standard Model but also for ultrahigh-energy cosmic particle physics. One of the key elements of these experiments measurements are hadron identification. The only detector technology which has a potential ability to separate hadrons in this energy range is Transition Radiation Detector (TRD) technology. TRD prototype based on straw proportional chambers combined with a specially assembled radiator has been tested at the CERN SPS accelerator beam. The test beam results and comparison with detailed Monte Carlo simulations are presented here.
Creation of global e-Infrastructure involves an integration of isolated local resources into common heterogeneous computing environment. In 2014 a pioneering work to develop a large scale data- and ...task- management system for federated heterogeneous resources has been started at the National Research Centre “Kurchatov Institute” (NRC KI, Moscow). As a part of this work, we have designed, developed and deployed a portal to submit payloads to heterogeneous computing infrastructure. It combines Tier-1, Cloud-infrastructure, and a supercomputer at the Kurchatov institute. This portal is aimed to provide a common interface to submit tasks to Grid sites, commercial and academic clouds and supercomputers. Integration of Tier-1 and the supercomputer has allowed to notably increase total CPU capacity available for Large Hadron Collider (LHC) experiments. The portal can be used not only for High Energy Physics (HEP) applications, but also for other compute-intensive sciences such as bioinformatics with genome and sequence analysis; astrophysics with cosmic rays analysis, antimatter and dark matter search, etc.
This article describes developed portal as a top layer for computing facilities infrastructure for High Energy Physics and other compute-intensive science applications. The article presents the results of using PanDA at NRC KI supercomputer/Cloud as underlying technology for the portal.
In this article, we propose methods for the generation of surface plasmon polaritons (SPPs), both carrying orbital angular momentum, and conventional ones, using vortex Bessel beams, and also ...investigate the propagation of SPPs along flat and cylindrical conductors. The possibility of their practical application is discussed and the first experimental results are presented.
Nuclear Instruments & Methods A, volume 927 (2019), pages 1-13 This work is dedicated to the study of a technique for hadron identification
in the TeV momentum range, based on the simultaneous ...measurement of the
energies and of the emission angles of the Transition Radiation (TR) X-rays
with respect to the radiating particles. A detector setup has been built and
tested with particles in a wide range of Lorentz factors (from about $10^3$ to
about $4 \times 10^4$ crossing different types of radiators. The measured
double-differential (in energy and angle) spectra of the TR photons are in a
reasonably good agreement with TR simulation predictions.
This document collects the proceedings of the PHOTON 2017 conference ("International Conference on the Structure and the Interactions of the Photon", including the 22th "International Workshop on ...Photon-Photon Collisions", and the "International Workshop on High Energy Photon Colliders") held at CERN (Geneva) in May 2017. The latest experimental and theoretical developments on the topics of the PHOTON conference series are covered: (i) \(\gamma\,\gamma\) processes in e\(^+\)e\(^-\), proton-proton (pp) and nucleus-nucleus (AA) collisions at current and future colliders, (ii) \(\gamma\)-hadron interactions in e\(^\pm\)p, pp, and AA collisions, (iii) final-state photon production (including Standard Model studies and searches beyond it) in pp and AA collisions, and (iv) high-energy \(\gamma\)-ray astrophysics. These proceedings are dedicated to the memory of Maria Krawczyk.
