232Th/233U fuel cycle is an alternate candidate for future nuclear energy. Neutron-induced fission cross section of 232Th one the important data if using thorium as in future. 232Th(n, f) sections from 1 to 300 MeV were measured at China Spallation Neutron Source (CSNS) Back-streaming neutron facility (Back-n) relative 235U(n, and n-p scattering. A fast ionization chamber measurement (FIXM) a proton recoil telescope (PRT) used perform measurement. The energy this reaches up which supposed be...
The Particle And Astrophysical Xenon Experiment III (PandaX-III) is an experiment to search for the Neutrinoless Double Beta Decay (NLDBD) using 200 kg radio-pure high-pressure gaseous xenon TPC with Micromegas detectors at both ends and cathode in middle. A small-scale equipped 7 Microbulk developed as prototype detector. 128 channels are readout following X-Y design strips of 3 mm pitch (64 each direction) from one module. Highly integrated front-end electronics composed 4 cards 1024...
Abstract The Back-n white neutron source (known as Back-n) is based on back-streaming neutrons from the spallation target at China Spallation Neutron Source (CSNS). With its excellent beam properties, e.g., a flux of approximately 1.8×10 7 n/cm 2 /s 55 m target, energy range spanning 0.5 eV to 200 MeV, and time-of-flight resolution few per thousand, along with equipped physical spectrometers, considered be among best facilities in world for carrying out nuclear data measurements. Since...
Differential and angle-integrated cross sections for the $^{10}$B($n, α$)$^{7}$Li, α$$_{0}$)$^{7}$Li α$$_{1}$)$^{7}$Li$^{*}$ reactions have been measured at CSNS Back-n white neutron source. Two enriched (90%) $^{10}$B samples 5.0 cm in diameter ~85.0 $μ$g/cm$^{2}$ thickness each with an aluminum backing were prepared, back-to-back mounted sample holder. The charged particles detected using silicon-detector array of Light-charged Particle Detector Array (LPDA) system. energy E$_{n}$ was...
Abstract Accurate cross sections of neutron induced fission reactions are required in the design advanced nuclear systems and development theory. Time projection chambers (TPCs), with their track reconstruction particle identification capabilities, considered best detectors for high-precision section measurements. The TPC developed by back-streaming white source (Back-n) team China Spallation Neutron Source (CSNS) was used as fragment detector In this study, 232 Th( n , f ) reaction at five...
The back-streaming neutron beam line (Back-n) was built in the beginning of 2018, which is part China Spallation Neutron Source (CSNS). Back-n first white China, and its main application for nuclear data measurement. For most neutron-induced reaction measurements based on facilities, gamma rays accompanied with one important experimental backgrounds. back streaming transported directly from spallation target to station without any moderator or shielding, flux in-beam much larger than those...
Abstract The capture cross sections of the 169 Tm reaction were measured at back streaming white neutron beam line (Back-n) China Spallation Neutron Source (CSNS) using four C 6 D liquid scintillation detectors. background subtraction, normalization, and correction carefully considered in data analysis to obtain accurate sections. For resonance 3.9 eV, R -matrix code SAMMY was used determine parameters with internal normalization method. average for energy between 30 300 keV extracted...

This paper shows the structure and performance of test results CSNS. photomultiplier tube (PMT) is chosen as detector this system. In order to acquire time information from PMT, an designed. The mainly includes one front-end board (FEB), four time-to-digital converter (TDC) boards clock distribution module (CDM). There are 256...
Differential cross-section data for the n-p and n-d elastic scattering ( 1 H( n, el ), 2 H(n, el)) are collected analyzed from EXFOR library. For E n > 20 MeV, experimental results both reactions scarce with large uncertainties discrepancies in general. ≤ lack systematicness, most of which were measured around = 14 MeV even though differential cross sections keV region recommended as standard. Taking these facts into account, more accurate systematic measurements planned. The experiments...
This paper explores the application of Adaptive Traffic Signal Control (ATSC) systems integrated with Information and Communication Technology (ICT) Internet Things (IoT) to improve urban traffic management. ATSC utilize real-time data from various sensors cameras adjust signal timings dynamically, aiming reduce congestion enhance flow efficiency. The study highlights how these process react live conditions, discussing implementation machine learning models optimization algorithms that...
