The China Spallation Neutron Source (CSNS) is an accelerator-based multidisciplinary user facility located in Dongguan, Guangdong, China. It was launched 2011 and started delivering neutron beams to users March 2018. CSNS complex consists of H− linear accelerator, a rapid cycling synchrotron that accelerates the beam 1.6 GeV, solid tungsten target station, various instruments for spallation applications. This paper focuses on vacuum system from ion source Drift Tube Linac, aiming review...
Abstract The 6 Li( n , t ) 4 He reaction was measured as the first experiment involving neutron-induced charged particle emission reactions at CSNS (China Spallation Neutron Source) Back-n white neutron source. differential cross-sections of 15 detection angles ranging from 19.2° to 160.8° are obtained 1.0 eV 3.0 MeV 80 energy points; for 50 points below 0.1 they reported time. results indicate that anisotropy emitted tritium is noticeable above E = 100 eV. angle-integrated also obtained....
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...
A new measurement of the neutron-induced fission cross section $^{236}\mathrm{U}$ relative to standard $^{235}\mathrm{U}(n,f)$ from 0.4--40 MeV was carried out by time-of-flight method and a multicell fast ionization chamber at China Spallation Neutron Source-Back-n white neutron source. The measured resonance peaks distribution event-energy spectrum reaction are in good agreement with that ENDF/B-VIII.0 evaluation, which confirms reliability experimental setup....
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...
The China spallation neutron source (CSNS) was built and started running since 2018. It produces neutrons by impinging 1.6 GeV protons onto a tungsten target with 25 Hz repetition frequency. A beam line exploiting the back-streaming (Back-n) mainly for nuclear data measurement commissioning simultaneously CSNS in There are two experimental endstations along Back-n line: endstation 1 (#ES1) flight path of about 55 m 2 (#ES2) 76 m. energy spectra both #ES1 #ES2 were measured it is important...
The Chinese spallation neutron source was completed in May 2018 and then subsequently commissioned. Back-streaming white beam line can be used nuclear data measurement, physics research, technology. In these experiments, it is necessary to know the energy spectrum, flux, profile of beam. this paper, we present preliminary measurements parameters. spectrum flux are measured by time-of-flight method with a fission chamber equipped <sup>235</sup>U <sup>238</sup>U samples...
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...
