[en] The ASP accelerator is primarily a low energy high current deuteron accelerator which generates neutrons by bombarding targets impregnated with either deuterium or tritium. The accelerated deuterons have sufficient energy to cause either the D-D or D-T fusion reactions to occur and hence generate neutrons of 2 MeV and 14 MeV respectively. The ASP facility is the UK 14 MeV primary neutron standard and is accredited by the National Physical Laboratory. (author)

[en] The “Neutrons For Science” (NFS) facility will be a component of the SPIRAL-2 laboratory under construction at Caen (France). The SPIRAL-2 facility will be dedicated to the production of high intensity of Rare Ions Beams (RIB). Additionally to the RIB production, two Linag Experimental Areas (LEA) will be constructed in order to use stable beams (protons, deuterons as well as heavy ions) delivered by the accelerator: NFS is one of them. It will be composed of a pulsed neutron beam for in-flight measurements and irradiation stations for cross-section measurements and material studies. The beams delivered by the LINAG (linear accelerator of GANIL) will allow producing intense pulsed neutrons sources in the 100 keV to 40 MeV energy range. Continuous and quasi-monokinetic energy spectra will be produced by the interaction of deuteron beam on thick Be converter and by ⁷Li(p,n) reaction on thin converter respectively. The flux at NFS will be up to 2 orders of magnitude higher than those of other existing time-of-flight facilities in the 1 MeV - 40 MeV range. Irradiation stations for neutron, proton and deuteron induced reactions up to 40MeV will also allow to perform cross-sections measurements by activation technique. NFS will be a very powerful tool for fundamental research as well as applications like the transmutation of nuclear waste, design of future fission and fusion reactors, nuclear medicine or test and development of new detectors. The facility and its characteristics are described, and several examples of the first potential experiments are presented. (author)

[en] The MONNET (MONo energetic NEutron Tower) facility is used for research on neutron-induced reactions with mono-energetic neutrons. MONNET is based on a 7 MV Van-de-Graaff-accelerator, where the accelerated ions, mainly protons and deuterons, are used to produce the neutrons by means of reactions on ⁷Li, tritium and deuterium-containing targets. Neutrons with energies between practically 0 keV up 10 MeV and between 12.5 and 24 MeV can be produced. However, between E_n = 7 and 10 MeV and above 19 MeV secondary neutron-producing reactions have to be taken care of. The measurement program focuses on fission research and neutron-induced reaction cross-sections. The MONNET facility also contributes to the nuclear science education and hosts PhD students and post-doc fellows on a regular basis. (author)

[en] The compact neutron-time-of-flight facility nELBE at the superconducting electron accelerator ELBE of Helmholtz-Zentrum Dresden-Rossendorf is currently being rebuilt. As the neutron radiator consists of a liquid-lead circuit no moderated neutrons are produced and also the background from capture gamma rays is very small. The useful neutron spectrum extends from some tens of keV to about 10 MeV. nELBE is intended to deliver cross section data of fast neutron nuclear interactions e.g. for the transmutation of nuclear waste and an improvement of neutron physical simulations of innovative nuclear systems. The new experimental hall will allow measurements of angular distributions in neutron scattering. Inelastic neutron scattering, e.g. on ⁵⁶Fe, has been studied with a double time-of-flight setup and with photon detectors to measure the gamma rays produced in the process. The neutron total cross sections of Au and Ta were determined in a transmission experiment. (author)

[en] The neutron spectrometer GNEIS [1,2] is based on the 1000 MeV proton synchrocyclotron of PNPI and intended for neutron-nucleus interaction studies utilizing the TOF-technique over a wide range of neutron energy from ~ 10^-2 eV up to ~ 800 MeV. The diagram of the experimental complex of the SC-1000 synchrocyclotron (including the hangar of the GNEIS TOF-spectrometer) at the PNPI is shown in Fig.1. The main parameters of the accelerator and GNEIS facility are given in Tables 1, 2. The general layout of the GNEIS is given in Fig.2. The water-cooled lead target situated inside the vacuum chamber of the accelerator is used as a pulsed spallation neutron source with maximal average intensity 3 * 10¹⁴ n/s (in 4π solid angle), the burst duration of ~10 ns and repetition rate up to 50 Hz. The neutron source is equipped with the polyethylene moderator. The mutual disposition of the target and moderator slabs is shown if the insert of Fig.2. The target and moderator can be moved remotely in the vertical and radial directions for optimum position. There are 5 holes for the neutron beams coming through 6 m thick heavy concrete shielding wall of the SC-1000 central machine room. The flight paths of the GNEIS are arranged so that only neutron beam N5 looks at the bare lead target being used for measurements in the fast and intermediate neutron energy range 100 keV to 800 MeV. The other paths used for measurements with neutron resonance energies of 1 eV-100 KeV are collimated so that their axes come through the moderator surface. This reduces the overloading effect induced in the detectors by γ-flash and fast neutrons

[en] This paper briefly describes the present status of the two prompt gamma ray measurement facilities, PGA and MPGA, installed on neutron beam lines attached to Japan Research Reactor-3 (JRR-3). The description includes those on the configuration of the beam line as well as the supporting system of the irradiation sample, neutron intensity at the irradiation position, and detectors used for the prompt gamma ray measurement, for each of the facilities.

[en] The Fusion Neutronics Source (FNS) facility is a 14 MeV neutron generator by deuteron-triton, DT, reaction. Its operation started in 1981. For more than 30 years various fusion-reactor related experimental studies especially for ITER project have been carried out. Many scientists have been accepted for years to perform leading edge neutronics studies using high energy neutrons. At present, the facility is back to the original state from Fukushima accident and is again open to outside scientists in Japan as a cooperated fusion research facility. (author)

[en] The Svedberg Laboratory (TSL) belongs to Uppsala University and exploits the Gustaf Werner cyclotron that delivers beams of protons and heavy ions to different beam lines and irradiation facilities. The main activities at TSL comprise proton treatment of cancer patients, radiation testing services, detector development, and nuclear data measurements. Currently, two high-energy neutron beam facilities are in regular use at TSL: (1) The quasi-monoenergetic neutron facility (QMN), and (2) The ANITA facility (Atmospheric-like Neutrons from thIck TArget). Both the facilities are driven by the proton beam from the cyclotron, with energy selectable in the range 20 – 180 MeV. The beam is pulsed, which allows one to use time-of-flight techniques. In the present report, we describe the neutron beam facilities at TSL, with focus on the QMN facility, including beam monitors as well as quality assurance and user support routines. Furthermore, we give an overview of neutron nuclear data measurements performed at the QMN facility. (author)

[en] Nuclear reaction department of the NPI Řež operates two different fast neutron sources: neutrons with continuous neutron spectrum (fusion/IFMIF like) up to 37 MeV from p+D₂O (flowing target) reaction and quasi-monoenergetic neutrons with energies up to 37 MeV from p+Li (C backing) reaction. Isochronous cyclotron U120M provides protons of energies up to 38 MeV and currents up to 20 μA. The integral-benchmark tests and the measurements of activation cross-sections are the core of the experimental program. Gamma-spectrometry is used for the investigation of daughter nuclei. Besides, the electronic hardness tests are routinely performed on white-spectrum fast neutrons. The spectral flux at the positions of irradiated samples is determined by the MCNPX simulation, backed by the experimental data from dosimetry foils, scintillation, and proton recoil telescope techniques. In the first part of this paper recent studies of the neutron spectra from the Li(C) target are described, as well as subsequent evaluation of the uncertainties of the measured reaction rates and of the extracted cross-sections. The second part describes the neutron detection techniques being introduced to our laboratory, the scintillation detector together with 500 MHz 8-bit digitizer card, which have been successfully used to obtain neutron spectra from the scintillator response and to record the limited Time-Of-Flight spectrum.
