Pulse pile-up poses an issue in the study of nuclear reactions and spectroscopy, arising when two pulses overlap, distorting data and compromising the accuracy of energy and timing details. Various digital and analogue techniques have been used to deal with pile-up interference. However, some pile-up events may include interesting pulses that require reconstruction.

The improvements in artificial intelligence, particularly the many flavours of Machine Learning (ML), add a powerful and versatile tool to data acquisition (DAQ) strategies. However, large and deep neural networks remain memory and compute intensive, limiting their usability at the edge. One of the most important aspect of integrating ML in a DAQ system is determining when and where...

With the increase of luminosity for accelerator colliders as well as a granularity of detectors for particle physics,
more challenges fall on the readout system and data transfer from detector front-end to computer farm and long term storage.
Modern concepts of trigger-less readout and data streaming will produce large data volumes being read from the detectors.
From a resource standpoint,...
High-speed data processing in DAQ using hardware accelerators such as GPU and FPGA has been gaining attention to accommodate the increasing intensity of accelerator beams.

Alveo U50 is one of the series of data center accelerator cards provided by Xilinx, which...
This work presents a 448-channel readout system integrated into a multi-strip ionization chamber for proton beam profile measurements. Miniaturized current-input ADCs inside the detector vessel provide direct digitization of charge collected on 1.5mm cathode strips. An FPGA configures ADCs dynamically and handles acquisition triggering and data processing, enabling real-time beam analysis....
Abstract: The discovery of the Higgs boson was a significant milestone in the history of particle physics. In pursuit of more precise measurement of the Higgs boson’s properties and interactions, Chinese high-energy physicists proposed the Circular Electron Positron Collider (CEPC) project. The silicon pixel vertex detector, which requires high spatial resolution, low material budget, and...
