MPT2321 is a 32-channel application-specific integrated circuit (ASIC) for silicon photomultiplier (SiPM), featuring high signal-to-noise ratio (SNR) and energy resolution, along with outstanding timing performance. Particularly for single-photon signals, the chip maintains a considerably high SNR. This article describes the fundamental architecture and key performance parameters of the chip. A series of measurements was conducted to evaluate the charge and time detection performance. First, the timing jitters of the analog and analog–digital mixed parts of the chip were measured by external charge injection. Then, a single photon spectrum was acquired by irradiating the SiPM (Hamamatsu S15639-1325PS, $1.3times 1.1$ mm, and pixel pitch of $25~mu $ m) with a high-precision pulsed laser, revealing clearly distinguishable peaks. Meanwhile, factors affecting timing jitter were also analyzed. Additionally, by utilizing light emitting diode (LED) emission, the single-photon spectra of different single-photon avalanche diode (SPAD) sizes (25, 35, and $40~mu $ m) were presented. Finally, the energy resolution was measured to be 8.7% $pm ~0.1$ % full width at half maximum (FWHM) at 511 keV using SiPM (Hamamatsu S14160-6050HS, $6times 6$ mm) coupled with lutetium yttrium oxyorthosilicate (LYSO) crystals ( $4times 4times 20$ mm). With time walk correction, a coincidence time resolution (CTR) of $289~pm ~6$ ps (FWHM) was achieved. Based on the results of these performance measurements, MPT2321 has been verified to be a qualified candidate for applications in several fields.
MPT2321是用于硅光电倍增管(SiPM)的32通道专用集成电路(ASIC),具有高信噪比(SNR)和能量分辨率,以及出色的时序性能。特别是对于单光子信号,芯片保持相当高的信噪比。本文介绍了该芯片的基本结构和关键性能参数。进行了一系列的测量来评估电荷和时间检测性能。首先,采用外部电荷注入法测量了芯片模拟部分和模数混合部分的时序抖动;然后,用高精度脉冲激光照射SiPM (Hamamatsu S15639-1325PS, $1.3 × 1.1$ mm,像素间距$25~mu $ m)获得单光子光谱,显示出清晰可分辨的峰。同时,分析了影响时序抖动的因素。此外,利用发光二极管(LED)发射,得到了不同尺寸单光子雪崩二极管(SPAD)(25、35和$40~mu $ m)的单光子光谱。最后,利用SiPM (Hamamatsu S14160-6050HS, $6 × 6$ mm)与氧化硅酸镥钇(LYSO)晶体($4 × 4 × 20$ mm)在511 keV下测得能量分辨率为8.7% $ $ pm ~0.1$ %半最大全宽(FWHM)。经过时间行走校正后,达到了$289~ $ pm ~ $ 6 ps (FWHM)的符合时间分辨率(CTR)。基于这些性能测量的结果,MPT2321已被证明是几个领域应用的合格候选者。

Neutrons have extensive applications across a wide range of fields. Diamond, with its excellent physical properties, holds great promise for neutron detection. However, the probability of thermal neutron interaction with diamond is relatively low, leading to the common use of 6LiF as a conversion layer. Beyond the inherent properties of the conversion layer, the detection efficiency of a detector is influenced not only by the spatial collection of secondary particles but also by the electrical characteristics of the device. Theoretical simulations can extract important parameters of the device and reveal significant physical processes. This article establishes a simulation framework using technology computer-aided design (TCAD), stopping and range of ions in matter (SRIM), and Garfield++. The simulation process involves using Sentaurus TCAD software to model the electrical characteristics of diamond detectors, employing SRIM to accurately simulate the deposition energy interaction of charged secondary particles with diamonds, and leveraging Garfield++ to generate detector signals accurately using electrical characteristics and nuclear reaction data. By simulating the signals of both planar and trench-type microstructure detectors, the research explores the impacts of various factors, including the applied voltage, the energy of secondary particles, and the angle of incidence on the dynamic response process. The proposed coupled simulation method plays a key role in the fabrication and experimental design of thermal neutron detectors, providing crucial insights and guidance to optimize detector performance and design readout circuits.
中子在许多领域都有广泛的应用。金刚石具有优良的物理性质,在中子探测方面具有很大的前景。然而,热中子与金刚石相互作用的概率相对较低,因此通常使用6LiF作为转换层。除了转换层的固有特性外,探测器的探测效率不仅受到二次粒子空间收集的影响,还受到器件电特性的影响。理论模拟可以提取器件的重要参数,揭示重要的物理过程。本文利用计算机辅助设计(TCAD)技术、物质中离子停止与范围(SRIM)技术和Garfield++技术建立了一个仿真框架。仿真过程包括利用Sentaurus TCAD软件对金刚石探测器的电学特性进行建模,利用SRIM精确模拟带电二次粒子与金刚石的沉积能量相互作用,利用Garfield++利用电学特性和核反应数据准确生成探测器信号。通过模拟平面型和沟槽型微结构探测器的信号,探讨了外加电压、二次粒子能量、入射角等因素对动态响应过程的影响。所提出的耦合模拟方法在热中子探测器的制造和实验设计中起着关键作用,为优化探测器性能和设计读出电路提供了重要的见解和指导。

Position-sensitive scintillator detectors are critical components in coded-aperture imaging and Compton imaging systems. Improving the position resolution and energy resolution of the detector is crucial for system performance. Traditional position sensitive scintillator detectors are constrained by the size of photoelectric readout devices and the number of readout channels, making it difficult to achieve both high position resolution and energy resolution at a low cost. This study presents a novel gamma-ray imaging detector that overcomes the traditional trade-off between position resolution, energy resolution, and cost. Using a high-resolution cerium-doped gadolinium aluminum gallium garnet (GAGG:Ce) scintillator array ( $0.5times 0.5times 5$ mm pixels) read out by a position-sensitive silicon photomultiplier (PS-SiPM) through its four anodes, we achieved direct position reconstruction without the use of a light-sharing technique. A 137Cs source was used to test the performance of this imaging detector. It demonstrated a clear segmentation of a $10times 10$ array with 7.2% [full-width-at-half-maximum (FWHM)] energy resolution for 662 keV, significantly simplifying the design of electronic readout systems.
位置敏感闪烁体探测器是编码孔径成像和康普顿成像系统的关键部件。提高探测器的位置分辨率和能量分辨率对系统性能至关重要。传统的位置敏感闪烁体探测器受到光电读出器件尺寸和读出通道数量的限制,难以以低成本同时实现高位置分辨率和能量分辨率。本研究提出了一种新的伽玛射线成像探测器,克服了传统的位置分辨率、能量分辨率和成本之间的权衡。利用位置敏感硅光电倍增管(PS-SiPM)通过其四个阳极读出的高分辨率掺铈钆铝镓石榴石(GAGG:Ce)闪烁体阵列($0.5 × 0.5 × 5$ mm像素),我们实现了直接位置重建,而无需使用光共享技术。用137Cs源测试了该成像探测器的性能。它展示了一个清晰的分割$10 × 10$阵列,能量分辨率为7.2%[全宽度半最大(FWHM)],为662 keV,显着简化了电子读出系统的设计。

Molten salt breeder reactors (MSBRs), which utilize molten fluoride salts as both fuel and coolant, are currently being researched and designed worldwide, offering inherent safety features, efficient fuel utilization, and the potential for thorium-based fuel cycles. Given the advanced development status of MSBRs, real-time emulation is essential for dynamic analysis studies, accommodating more detailed models and advanced control strategies. This article proposes a real-time digital-twin (RTDT) based on a hardware-in-the-loop (HIL) emulation on a field-programmable gate array (FPGA) for a multi-domain two-fluid MSBR model with a designed controller for validation and testing. A nonlinear explicit numerical solution with an appropriate step-size and ordinary differential equation (ODE) solver is carried out in a non-iterative fashion to achieve the required accuracy and real-time execution. The MSBR hardware emulation and closed-loop controller tests have been implemented on the parallel hardware architecture of the FPGA in real-time for dynamic analysis and performance evaluation. The FPGA-based hardware emulation has achieved an ultralow latency of $2.34~mu $ s, providing a remarkable 427-fold acceleration in faster-than-real-time (FTRT) performance. The designed controller performs well under transient and steady-state operating conditions, effectively stabilizing the MSBR system under perturbations, as validated on the RTDT.
熔盐增殖反应堆(MSBRs)利用熔融氟化物盐作为燃料和冷却剂,目前正在世界范围内进行研究和设计,具有固有的安全特性、高效的燃料利用以及钍基燃料循环的潜力。鉴于msbr的先进发展状况,实时仿真对于动态分析研究至关重要,可以提供更详细的模型和先进的控制策略。本文提出了一种基于现场可编程门阵列(FPGA)硬件在环(HIL)仿真的实时数字孪生(RTDT),用于多域双流体MSBR模型,并设计了用于验证和测试的控制器。采用非迭代的方式,采用适当的步长和常微分方程(ODE)求解器进行非线性显式数值解,以达到所需的精度和实时性。在FPGA的并行硬件架构上进行了MSBR硬件仿真和闭环控制器测试,实时进行了动态分析和性能评估。基于fpga的硬件仿真实现了2.34~ $ $ s的超低延迟,提供了427倍的超实时(FTRT)性能加速。在RTDT上验证了所设计的控制器在瞬态和稳态运行条件下的良好性能,有效地稳定了MSBR系统在摄动下的稳定性。
