mCBM@SIS18
No full textWe propose a full-system test-setup for the Compressed Baryonic Matter experiment CBM atSIS18 under the name mCBM@SIS18 (“mini-CBM”, later shortened to “mCBM”), comprisingfinal prototypes or pre-series components of all CBM detector subsystems. The primary aim is tostudy, commission and test the complex interplay of the different detector systems with the freestreamingdata acquisition and the fast online event reconstruction and selection. In particular, itwill allow to test the detector and electronics components developed for the CBM experiment aswell as the corresponding online/offline software packages under realistic experiment conditionsup to top CBM interaction rates of 10MHz.Commissioning and operating mCBM in 2018 and 2019 will prove the proper functioning ofthe detectors as well as the read-out electronics before the final series production starts. Theexperiences gathered during the operation of the complete mCBM campaign will be of highestvalue to minimize the commissioning time for the full CBM experiment at SIS100.With mCBM, the ambitious detector sub-systems, readout and data processing concept of CBMwill be validated on the base of a benchmark observable, namely the Λ production yield inAu+Au and Ni+Ni collisions at top SIS18 energies, which can be compared to publisheddata. The feasibility has been successfully demonstrated by performing Monte-Carlo simulationsincluding GEANT geometries of all mCBM detector subsystems and full detector response

mCBM@SIS18 2021/22
No full textThis beam time application submitted in June 2020 is a continuation request by the CBM Collaboration, following the proposal on the CBM full-system test-setup at the SIS18 facility under the name mCBM@SIS18 (short “mCBM”), which was fully granted in September 2017. The primary aim of the mCBM setup is to commission and optimize the complex interplay of the different detector systems with the triggerless-streaming data acquisition and the fast online event reconstruction and selection. In particular, it allows testing of the detector and electronics components developed for the CBM experiment as well as the corresponding online/offline software packages under realistic experiment conditions up to the top CBM interaction rates of 10 MHz
mCBM@SIS18 2023/24
No full textThis beam time application submitted in June 2022 is a continuation request by the CBM Collaboration to the General Program Advisory Committee (G-PAC) of GSI/FAIR, following the proposals which were granted in 2017 [4] and 2020 [5] within the FAIR phase-0 program of GSI / FAIR. The primary aim of mCBM@SIS18 (short “mCBM”) is to commission and optimize the complex interplay of the different detector systems with the triggerless-streaming data acquisition and the fast online event reconstruction and selection under realistic experiment conditions up to the top CBM interaction rate of 10 MHz. To validate the read-out and data processing concept of CBM the Λ production yield in Au + Au and Ni + Ni collisions at top SIS18 energies are measured with mCBM as a benchmark observable, which will allow comparison with published data by the FOPI and HADES experiment
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Technical Design Report for the CBM : Muon Chambers (MuCh)
Full text linkThis document describes the technical layout and the performance of the Muon Chamber (MuCh) System of the Compressed Baryonic Matter (CBM) experiment at FAIR. The MuCh system is designed to identify muon pairs which are produced in high-energy heavy-ion collisions in the beam energy range from 4 to 40 AGeV. The measurement of lepton pairs is a central part of the CBM research program, as they are very sensitive diagnostic probes of the conditions inside the fireball. At low invariant masses, dileptons provide information on the in-medium modification of vector mesons which is a promising observable for the restoration of chiral symmetry. At intermediate invariant masses, the dilepton spectrum is dominated by thermal radiation from the fireball reflecting its temperature. At invariant masses around 3 GeV/c2, dileptons are the appropriate tool to study the anomalous charmonium suppression in the deconfined phase. In the CBM experiment both electrons and muons will be measured in order to obtain a consistent and comprehensive picture of the dilepton physics
