The Heavy Ion Research Facility in Lanzhou (HIRFL) and the High-Intensity Heavy-ion Accelerator Facility (HIAF) are leading platforms for heavy ion scientific research in China. Several physics experiments are being under construction at HIAF, such as the Electron-ion collider in China (EicC), the China Hyper-Nuclear Spectrometer (CHNS), the High energy FRagment Separator (HFRS), etc....
Atom Switch-based FPGA (AS-FPGA) is a potential candidate for use in high radiation environments like future particle physics experiments using accelerator. We performed neutron and gamma-ray irradiation tests for the AS-FPGA. No Single Event Upsets (SEUs) were found at least up to 10$^{11}$ and 10$^{12}$ n/cm$^2$ with and without applying voltage, respectively. It tolerated Displacement...
Traditional approach of spectroscopy signals acquisition and analysis comprises digitization performed ideally by a high bit resolution and short sampling period flash ADC, followed by a subsequent digital processing requiring a high computational performance. However, some particular applications cannot implement that traditional approach while demanding comparable high spectroscopic...
Micro-pattern gaseous detectors (MPGDs) find wide-range applications in particle physics experiments, industry, and medical imaging, owing to their large area, fine spatial resolution, and relatively low material content within the sensitive region. However, the requirement of a large number of readout channels poses a challenge, limiting the application of MPGD to achieve higher accuracy and...
The High-Luminosity LHC (HL-LHC) proposes an ambitious physics program covering high-precision Standard Model (SM) measurements and advancing the searches for new physics. The efficient data gathering and precise events reconstruction in the intense environment of 200 proton-proton interactions per bunch-crossing (40 MHz) are essential for attaining the success of the HL-LHC program. To...
Nowadays backend electronics has been used with help of unified high speed link to provide the fast control and slow control (electronics parameter setting) to frontend electronics in addition to providing trigger preprocessing and data readout. In such a case, the link is normally shared by many front channels, the processing time in backend for those channels with low readout priority,...
The MEG II experiment, based at PSI in Switzerland, aims to detect rare muon decay events. A critical aspect of this experiment is the precise measurement of the timing of both the calorimeter and timing counters, achieving accuracy within a few picoseconds. This precision is made possible by employing the DRS4 Switched Capacitor Array ASIC alongside a sophisticated timing system. This system...
The Belle II Experiment, located in Japan with the SuperKEKB, an energy-asymmetric electronpositron collider, is the next generation of B-factories. SuperKEKB targets a luminosity of $6× 10^{35}\text{cm}^{-2} \text{s}^{-1}$, enabling unprecedented new physics investigations and Standard Model parameters measurements.
However, the increase in luminosity faces escalating challenges, notably in...
With the beginning of the Facility for Rare Isotope Beams (FRIB) era, data acquisition systems and analysis tools are required to keep up with new detector technologies for higher data rates and volumes. Recent upgrades to the FRIB Data Acquisition System (FRIBDAQ) enable sustained data throughput of $\approx$200 MB/s. Experiments utilizing this capability write large amounts of data to disk,...
We have developed a trigger-less data-streaming-type high- and low-resolution TDC called Str-HR(LR)TDC using an AMD Kintex-7 FPGA to develop a general-purpose trigger-less DAQ system in Japan. The trigger-less DAQ system shows promise as a leading candidate of the next standard of the DAQ field in the particle and nuclear experiments. The developed Str-TDCs has been designed for general use,...
A growing number of detectors produce data rates of more than 100 Gbit/s, which often necessitate software-defined data processing to operate. Because of its simplicity, UDP offers a straightforward method for integrating such detectors with online computing resources that host the data processing software. Nevertheless, conventional technologies—such as POSIX sockets—are either ineffective or...
