“…It monitors the beam state by recording the number of particles. The beam intensity of 12 C beam during the experiment was about 10 6 ions/s. The beam hit on the center of the target, which was fixed on the chamber.…”

“…For the purpose of improving the dose deposition accuracy of hadron therapy, many countries have carried out experiments of carbon beams of different energies bombarding on varieties of targets. Measurements of total and partial cross-sections of fregments for incident 12 C beams in water and polycarbonate at energies ranging from 200 to 400 MeV/u were made by Japan scientists (T. TOSHITO et al) in 2004 [5]. In 2008, to extend these data to lower energy, France scientists performed an experiment of a 95 MeV/u 12 C beam on thick PMMA targets [6].…”

“…Our team has been engaged in experimental research in heavy ion nuclear physics [11,12,13,14], to learn more about the fragmentation reaction of 12 C , we have carried out an experiment of 80.5 MeV/u 12 C beam borbarding on C, W, Cu, Au and Pb targets. The energy spectrums and cross-sections of light particles have been measured at 30 • , 60 • and 120 • away from beam.…”

To get the energy spectrum distribution and cross-sections of emitted light charged particles and explore the nuclear reaction, a experiment of 80.5 MeV/u 12 C beam bombarding on C, W, Cu, Au, Pb targets has been carried out at Institute of Modern Physics, Chinese Academy of Science. 30 • , 60 • and 120 • relative to the incident beam have been detected using three sets of telescope detectors. The method of ∆E-∆E-E was used for particle identification. The results indicate that there is a tendency that heavier targets have larger double differential cross-sections and the emitted fragments are more likely to go forward. Besides, the decrease of cross-sections of fragments producing with the increasing emitted angles may follow some kind of pattern.

“…a subcritical lead-bismuth reactor, a heavy metal spallation target and an intense-beam proton linac [2]. During the early stages of ADS projects, some experiments [3][4][5][6][7], which coupled the proton accelerator with the spallation target, have been performed by the researchers. However, the experimental studies about the coupling behaviors between the nuclear reactor and the spallation target have been rarely investigated.…”

Measurement of a cylindrical tungsten target reactivity worth has been performed on the light water zero-power reactor of VENUS-II at China Institute of Atomic Energy (CIAE) in order to verify the neutron evaluated data related to the engineering design of Chinese initiative Accelerator Driven Systems (CiADS). The reactivity worth of the tungsten target was measured and processed as -1.234±0.114mk by a period method. The experimental result was compared with the simulation ones calculated by MCNP with five different libraries, i.e., ENDF/B-VII.0, ENDF/B-VII.1, JENDL-4.0, CENDL-3.1 and JEFF-3.2. By comparing the results of experiment and simulation, the simulated results from ENDF/B-VII.0, JENDL-4.0 and JEFF-3.2 are higher than the experimental result, however that from CENDL-3.1 is lower. The result from ENDF/B-VII.1 library shows better agreement with the experiment one and the relative deviation is less than 2%. Through the analysis of the differences of the results, non-tungsten elements cross sections in the ENDF/B-VII.1 mainly affect the tungsten radiation capture and elastic scattering reaction rates in the energy range of 10-9-10-7 MeV, which results in a better simulated tungsten target reactivity worth value. Therefore, it is recommended that the tungsten target reactivity worth should be calculated with the ENDF/B-VII.1.
