Reconfigurability is one of the main advantages of FPGAs over ASICs. Partial reconfiguration exploits this ability even further by allowing to exchange the logic on predefined FPGA regions at runtime. This is especially relevant in heterogeneous SoCs, combining FPGA fabric with conventional processors on a single die. Tight integration and supporting frameworks, such as the FPGA subsystem in...
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...
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...
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,...
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,...
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...
Detectors at future colliders will rely on the ability to perform 4D tracking with < 50 ps resolution. As a stepping stone towards these future detectors we have developed a prototype ASIC in 28 nm CMOS, MetaRock, which consists of analog front-end (AFE), time-to-digital converter (TDC) and embedded testing circuits. The AFE and TDC aim to achieve 50 ps timing resolution while maintaining all...
