“…Later, it was adapted for other experiments and integrated with the described DMA engine. GERI receives the hit data sent by the STS-XYTER [49] readout ASIC and delivered via the GBTxEMU [50] board. The data received from several (up to 7) GBTxEMU boards are concentrated, supplemented with the metadata describing their source, packed into 256-bit words, and delivered via the AXI-Stream interface to the DMA engine.…”

FPGA-based cards for data concentration and readout are often used in data acquisition (DAQ) systems for high-energy physics experiments. The DMA engines implemented in FPGA enable efficient data transfer to the processing system’s memory. This paper presents a versatile DMA engine. It may be used in systems with FPGA-equipped PCIe boards hosted in a server and MPSoC-based systems with programmable logic connected directly to the AXI system bus. The core part of the engine is implemented in HLS to simplify further development and modifications. The design is modular and may be easily integrated with the user’s DAQ logic, assuming it delivers the data via a standard AXI-Stream interface. The engine and accompanying software are designed with flexibility in mind. They offer a simple single-packet mode for debugging and a high-performance multi-packet mode fully utilizing the computational power of the processing system. The number of used DAQ cards and the amount of memory used for the DMA buffer may be modified in the runtime without rebooting the system. That is particularly useful in the development and test setups. This paper also presents the development and testing methodology. The whole design is open-source and available in public repositories.

“…The Master Board is also used for control of the underlying electronics, and setting the required readout clock values. The data is sent out through eight GigaBit Transceiver (GBTX) serialisers [86], which combine the parallel data streams from the FPGAs into a serial stream, and send it via four Versatile Twin Transmitter (VTTx) modules [87]. The data from each SiPM is transmitted through a single optical fibre, and thus one BE link corresponds to one SiPM.…”

Impact paragraph Acknowledgements 2.4. Λ 0 b → Λ + − decays 2.5. Towards measuring C 9 and C 10These resonant decays are experimentally useful as they are used to validate the analysis procedure, as will be described in Chap. 4. In contrast to mesonic b → s decays, the Λ 0 b → Λ + − decays have a larger decay rate in the high q 2 region compared to the low q 2 region, allowing the search for new physics in a different, unexplored kinematic region. This is caused by the different form factors, the non-perturbative QCD effects that describe the transition between the initial and final state hadrons, of the Λ 0 b → Λ + − decays and by the difference in spin structure. The LHCb experimentThe analyses described in this thesis use data collected by the Large Hadron Collider beauty (LHCb) experiment at CERN. The LHCb experiment is located at interaction point 8 of the Large Hadron Collider (LHC). The LHC accelerates and collides proton beams (pp collisions) to a maximum of 7.5 TeV. This chapter describes the LHC and the LHCb experiment, the different LHCb subdetectors, the used trigger system, and the use of event simulation within the experiment. 3.4. Particle identification 10 MeV, which is used for the signal extraction in the physics analyses.

STRASSE: a silicon tracker for quasi-free scattering measurements at the RIBF

et al. 2023

View full text Add to dashboard Cite

Silicon Tracker for RAdioactive nuclei Studies at SAMURAI Experiments is a new detection system under construction for quasi-free scattering (QFS) measurements at 200–250 MeV/nucleon at the RIBF facility of the RIKEN Nishina Center. It consists of a charged-particle silicon tracker coupled with a dedicated thick liquid hydrogen target (up to 150-mm long) in a compact geometry to fit inside large scintillator or germanium arrays. Its design was optimized for two types of studies using QFS: missing-mass measurements and in-flight prompt $$\gamma $$ γ -ray spectroscopy. This article describes (i) the resolution requirements needed to go beyond the sensitivity of existing systems for these two types of measurements, (ii) the conceptual design of the system using detailed simulations of the setup and (iii) its complete technical implementation and challenges. The final tracker aims at a sub-mm reaction vertex resolution and is expected to reach a missing-mass resolution below 2 MeV in $$\sigma $$ σ for (p, 2p) reactions when combined with the CsI(Na) CATANA array.
