Abstract— This work presents a low-area and high-precision 8-channel 10-bit resistor-floating-resistor-string (RFR) digital to analog converter for multi-voltage threshold digitizer in PET medical imaging equipment. Two-stage segment structure is adopted to reduce the chip area, which the first-stage coarse quantization circuit can be shared among each channel. And the RFR-DAC combines a 6-bit...
This paper presents the design and the test results of a 25 Gbps VCSEL driving ASIC fabricated in a 55 nm CMOS technology for detector front-end readout. This VCSEL driving ASIC is composed of an input equalizer stage, a pre-driver stage and a novel output driver stage. The input equalizer stage adopts a 5-step CTLE structure to compensate the high frequency loss at the PCB traces, bonding...
This paper presents the novel design and the test results of a 4×14-Gbps Vertical-Cavity Surface-Emitting Laser (VCSEL) driver ASIC fabricated in a 65 nm CMOS process for particle physics experiments. The driver ASIC includes four independent channels and a I2C module. Each channel consists of a limiting amplifier stage, a novel output driver stage and bias circuits. The limiting amplifier...
Digital bandwidth interleaving (DBI) technology is a method that can simultaneously improve the bandwidth and sampling rate of sampling system. However, its waveform reconstruction algorithm is so complicated that it is impossible to realize real-time waveform reconstruction. This paper proposes a frequency-domain waveform reconstruction method for DBI sampling system to improve the waveform...
As magnetic fusion draws closer to commercial viability, experiment pulse

We present the conceptual design of carrier board for isolated, dual-channel,
2MSPS 18bit ADC modules designed with the requirements of COMPASS-U and other
future experiments in mind.
The carrier board was designed to be compatible with the...
The Monolithic Active Pixel Sensor (MAPS) has been widely used in nuclear and particle physics. The real-time particle tracking applications at the Heavy Ion Research Facility in Lanzhou (HIRFL) and the High-Intensity heavy-ion Accelerator Facility (HIAF) require MAPS to measure the position, energy deposition, and arrival time of the particle hits. Thus, a MAPS with such capability is being...
As the leading research platform of heavy-ion science in China, the heavy-ion physics and heavy-ion applications at the Heavy Ion Research Facility in Lanzhou (HIRFL) and the High-Intensity heavy-ion Accelerator Facility (HIAF) drive the development of new detector technology. A Monolithic Active Pixel Sensor (MAPS) is being designed in a 130nm process for real-time beam monitoring...
The ITER magnetics diagnostics will condition, validate, and supply magnetic sensors outputs to key operational systems, including the plasma control system (plasma position, shape, vertical velocity and MHD instabilities); the interlock system (plasma current for machine protection) and the data-archiving system for post-pulse data analysis (study of the plasma physics).
A combination of...
To meet the multi-channel and high trigger rate sampling requirements of CIGAR (ChIna Gamma trAcking aRray) single-point electrode and multi-electrode HPGe (high-purity germanium) detectors, a high-speed and high-precision dedicated readout electronics system “Wukong” based on Xilinx ZYNQ XC7Z100 was developed, including the system motherboard and high-speed, high-precision ADC mezzanine card...
The calorimeter is one of the most important detectors in the field of particle physics. In recent years, the research of SiPM as the sensor of the calorimeter has attracted a lot of attention. There are two ways of traditional SiPM readout circuit, one is multi-channel readout, setting readout paths with different gains, the disadvantage is that the power consumption is high and the layout...
The upcoming sPHENIX experiment, scheduled to start data taking at the BNL Relativistic Heavy Ion Collider in 2023, and the future EIC experiments will employ sophisticated state-of-the-art, high-rate detectors to study high energy heavy ion and electron-ion collisions, respectively. The resulting large volumes of raw data far exceed available DAQ and data storage capacity.

Silicon Photomultipliers (SiPMs) are new type of high-performance semiconductor detectors, which inherit most of the advantages of semiconductor detectors and have good performance in terms of gain, signal-to-noise ratio and response speed. SiPM also has high photon detection efficiency and excellent time resolution, which is comparable to high-performance PMT. In this paper, the timing...
The CSR External-target Experiment (CEE) at the Heavy Ion Research Facility at Lanzhou (HIRFL) will be the first large-scale experiment in nuclear physics independently developed in China, covering the GeV energy regime.
