Abstract “A Craftsman Must Sharpen His Tools to Do Job,” said Confucius. Nuclear detection and readout techniques are the foundation of particle physics, nuclear astrophysics reveal nature universe. Also, they being increasingly used in other disciplines like power generation, life sciences, environmental medical etc. The article reviews short history, recent development, trend techniques, covering Semiconductor Detector, Gaseous Scintillation Cherenkov Transition Radiation Readout...
α particles must be monitored to managed as radioactive diagnostic agents or nuclear activity indicators. The new generation of perovskite detectors suffer from limited energy resolution, which affects spectroscopy and imaging applications. Here, we report that the solution-grown CsPbBr3 crystal exhibits a low stable dark current (34.6 nA·cm−2 at 200 V) by thinning as-grown decrease high concentration CsPb2Br5 phase near surface. introduction Schottky electrode for detector further reduces...
Accurate self-localization and mutual state estimation are essential for autonomous aerial swarm operations in cooperative exploration, target tracking, search-and-rescue missions. However, achieving reliable formation positioning GNSS-denied environments remains a significant challenge. This paper proposes UAV system that integrates inertial navigation with data link-based relative measurements to improve accuracy. Each independently estimates its flight real time using onboard IMU through...
The Circular Electron Positron Collider (CEPC) has been proposed to enable more thorough and precise measurements of the properties Higgs, W, Z bosons, as well search for new physics. In response stringent performance requirements vertex detector CEPC, a baseline prototype was tested characterized first time using 6GeV electron beam at DESY II Test Beam Line 21. is designed with cylindrical barrel structure that contains six double-sided modules (ladders). Each side ladder includes...

In the International Linear Collider, charged particles that come from beam background may hit on vertex detector and generate elongated clusters, leading to increasing of useless data in system. previous work, we conducted feasibility study a CMOS pixel sensor with on-chip artificial neural networks order remove clusters. The principle component analysis is good approach, which was developed FPGA implementation for feature extraction. However, method challenging ASIC implementation. this...
A high amount of hits on the vertex detector International Linear Collider (ILC) are generated by beam background, which leads to an increase in data flow system. Charged particles coming from background have low momentum, resulting generation elongated clusters. The CMOS pixel sensor (CPS), integrates pre-processing functions and on-chip artificial neural networks (ANNs), could remove these Clustering is first step for used collect clusters raw data. In this article, a pixel-level...
