High-energy physics experiments require significant computing resources to operate their high-level trigger systems. Typically, these systems are constructed as extensive computing farms with cutting-edge expensive hardware to provide sufficient computing power. Usually located on-site, these systems process detector data in real time and minimize their latency. In this paper, we present an...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino experiment that will probe the properties of these elusive particles with unparalleled precision. It will also act as an observatory for neutrino bursts caused by nearby supernovae, in the event that one occurs while the experiment is in operation. Given these goals, the DUNE trigger and DAQ system must be able to...
In this paper, we present the design of the hybrid
event builder algorithm for the Belle II DAQ. The event builder
is implemented in PCIe40 FPGA boards and reads up to 48
127 MB/s channels per board. The first version of the event
builder impemented the algorithm entirely in the firmware of
the FPGA. But due to limited onboard memories, there are
hard limitations on the operation...
This paper presents the development and current status of the new data acquisition (DAQ) system of photoproduction exepriments with the LEPS2 detector at SPring-8. The LEPS2 DAQ system is based on the network-distributed DAQ-middleware framework, which includes gatherers collecting data from detector sub-systems, mergers integrating data
from gatherers, event builder and logger writing data...
The Timing Distribution System of the LHCb Experiment at CERN employs FPGA firmware cores to ensure synchronicity across all Front-End and Back-End modules of the Detector Readout System. The control signals are centrally generated in an FPGA-based card, the Readout Supervisor (SODIN), which receives the LHC synchronous clock, and packs timing and control signals into data words (TFC data),...
The increased instantaneous luminosity of the LHC in Run 3 brings the need for the upgrade of the ATLAS trigger system. The newly commissioned Phase-I L1Topo system, which replaces its Phase-0 predecessor, processes data from the Feature Extractors (FEXes) and the upgraded Muon to Central Trigger Processor Interface (MUCTPI) to perform topological and multiplicity triggers. The L1Topo system...
The JNE(Jinping Neutrino Experiment) experiment is located in an underground laboratory in Jinping Mountain, China, with the ultimate goal of building a 500 ton detector with 4000 channels for detecting and studying solar neutrinos. This goal poses a huge challenge to electronic design. Therefore, 30-channel data acquisition system will be built for the 1-ton prototype detector to verify the...
By the time of this conference, the sPHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) will have started its second data taking run. sPHENIX is the first major upgrade to a Nuclear Physics experiment in the US in 2 decades, and will be the final experiment taking data at RHIC before the construction of the Electron-Ion Collider. In 2023, the experiment went through a...
