High-precision energy measurement is required in the readout systems for the Multi-purpose Time Projection Chambers (MTPC) at China Spallation Neutron Source (CSNS) back-streaming white neutron source (Back-n). Considering the size and power consumption limitation of the readout electronics, a new prototype front-end ASIC was designed. The prototype ASIC integrates 16 readout channels, each...
The use of Field Programmable Gate Array (FPGA) based systems are becoming more widespread within Intelligent Instrumentation and Control (I&C) field. This is due to the advantages they offer in terms of timing, versatility and safeness against cyber-attacks. Traditionally, these devices had been mostly programmed using low-level Hardware Description Languages (HDL), but the use of high-level...
In the Compact Muon Solenoid (CMS) experiment at CERN, Geneva, a large number of High-granularity calorimeter (HGCAL) sensor modules are fabricated in advanced laboratories around the world. Each sensor module contains about 700 checkpoints for visual inspection thus making it almost impossible to carry out such inspection manually. As artificial intelligence is more and more widely used in...
Signal multiplexing is always necessary to decrease a large number of readout channels in PET scanners. Demultiplexing the encoded data with precise channel position and magnitude is significant for medical imaging research. The motivation for this paper is to design an efficient and reliable model for demultiplexing data from Prism-PET detectors. We develop a data-driven method, which...
CDEX project which aims at search of Dark Matter, will soon come to CDEX-100 period in about 2 years. This work has designed an readout system (Readout over PCIe, RoPe) for CDEX-100. The whole system is built on Xilinx Zynq 7Z100 SoC and support 80Gbps of input bandwidth based on 2 QSFP+ optical link and 40Gbps of output bandwidth based on PCIe Gen2 x8 link.
Considering RoPe's condition, we...
In high-precision radionuclide measurements, ADC is usually used to sample the detector signal, and FPGA is used to preprocess the acquired data, then the large amount of acquired data is transmitted to PC for further processing. In the case of high radioactivity, the acquisition system generates a large amount of data. At the same time, it is necessary to control the running state and...
Applications of machine learning (ML) are growing by the day for many unique and challenging scientific applications. However, a crucial challenge facing these applications is their need for ultra low-latency and on-detector ML capabilities. Given the slowdown in Moore's law and Dennard scaling, coupled with the rapid advances in scientific instrumentation that is resulting in growing data...
The Heavy Ion Research Facility at Lanzhou (HIRFL) and the High-Intensity heavy-ion Accelerator Facility (HIAF) are the leading heavy-ion physics centers. Heavy-ion physics experiments at HIRFL and HIAF with significantly increased scale have put forward urgent requirements on high-speed and high-density data transmission links. In addition, the strong radiation environment is a significant...
Machine learning methodologies have increasingly been employed in high-energy physics research. The interest in ML for physics is due to the incredibly high amount of data which is produced by particle detectors, which makes it impossible for researchers to analyze it in real time. Another issue with detector data is that it is not labeled, i.e. the distinction between signal and background is...
For environmental, sustainable economic and political reasons, recycling processes are becoming increasingly important, aiming at a much higher use of secondary raw materials. Currently, for the copper and aluminum industries, no method for the non-destructive online analysis of heterogeneous materials are available. The Promt Gamma Neutron Activation Analysis (PGNAA) has the potential to...
Finite Impulse Response (FIR) filters offer a powerful, flexible approach to maximizing the sensitivity in digital spectroscopy. For example, the trapezoid filter [1] removes the exponential background from a tail pulse and integrates the decaying charge collected over time to account for ballistic deficit, yielding a robust pulse energy amid uncertainties in the arrival time. Higher order...
We have developed a digital waveform processing system with Xilinx RFSoC.It is optimized system for experiments at RIKEN RI Beam Factory(RIBF) that is an accelerator facility in Japan. This system is aimed at simultaneous measurement of TOF with high-resolution and ΔE using plastic scintillators. For this development, Xilinx RFSoC that includes 4GHz FADC, FPGA, and CPU has been adopted. Using...
The ITER Interlock Control System (ICS) requires the application of the IEC61508 standard for all mission-critical (known as investment protection) control functions. Such functions must detect the events of the integrated physical processes and distribute them to the actuators with hard real-time constraints on the order of milliseconds or sometimes microseconds.
Systems that can achieve...
Abstract—There is a pressing market demand to minimize the test time of Prompt Gamma Neutron Activation Analysis (PGNAA) spectra measurement machine, so that it could function as an instant material analyzer, e.g. to classify waste samples instantaneously and determine the best recycling method based on the detected compositions of the testing sample.
This article introduces a new development...
