“…A time pick-off was placed 1 meter upstream from the neutron production target to perform TOF measurements with a time resolution of 2 ns. Solid targets of Ti-deuteride or Ti-tritide manufactured by SODERN [9] and a deuterium gas target elaborated in the laboratory are used. The solid targets are 1 mg/cm 2 thick…”

The (n,xn) reactions play an important role in many nuclear applications like accelerator-driven systems, fast neutron reactors or nuclear medicine. Their experimental study is necessary to improve and validate simulation models especially between about 10 MeV and 200 MeV where the pre-equilibrium process becomes significant and data are scarce. A new experimental set-up has been built near the Tandem 7MV of Bruyères-le-Châtel (France) in order to perform new (n,xn) double-differential cross section measurements. It is composed of a 4π neutron detector and a low background neutron beam line. The detector, called CARMEN, is a tank containing 1 m 3 of Gd-loaded liquid scintillator. It is intended to neutron multiplicity distributions measurements event by event with a very high efficiency (85% to fission neutrons). Due to its high sensitivity, CARMEN requires a well collimated neutron beam line as well as a low background. The neutrons are produced by nuclear reactions between proton or deuteron primary beams and tritium or deuterium targets surrounded by a heavy concrete shielding through which a channel was made defining the neutron beam. Neutron beams between 4 and 25 MeV are thus available. The entire set-up (detector and neutron production) and original experiments will be presented.The energy spectra of tagged (n,2n) reactions have been measured in the 8.3 -13.3 MeV range on several targets. The results are compared with the predictions of the nuclear reaction code TALYS.

“…[1][2][3] The tritiated metallic film where the D-T reaction occurs is one of the important components of a neutron generator. [4,5] In recent years, zirconium tritiated (ZrT x ) is chosen as a candidate material for the target film because of the excellent hydrogen storage properties [6,7] and higher thermal stability than titanium tritiated (TiT x ). [8,9] However, the neutron beam flux and duration are influenced by the target film properties during D ions implantation.…”

Zirconium tritiated (ZrT x ) is an alternative target material for deuteron-triton (D-T) reaction neutron generator. The isotopic replacement and microstructure evolution induced by hydrogen isotope implantation could significantly affect the performance of the target film. In this work, the zirconium deuteride film deposited on Mo/Si substrate was implanted by 150 keV protons with fluence from 1×10 16 to 1×10 18 protons/cm 2 . After implantation, the depth profiles of retained hydrogen (H) and deuterium (D) in these target films were analyzed by elastic recoil detection analysis (ERDA), and time of flight-secondary ion mass spectrometry (ToF-SIMS). Additionally, the microstructure evolution was also observed by x-ray diffraction (XRD) and scanning electron microscope (SEM). The D concentration in the ZrD x film decreased versus the proton implantation fluence. An analytical model was proposed to describe the hydrogen isotopic trapping and exchange as functions of incident protons fluence. Additionally, the XRD analysis revealed that no new phase was formed after proton implantation. Furthermore, circular flakings were observed on the ZrD x surface from SEM images at fluence up to 1×10 18 protons/cm 2 , and this surface morphology was considered to associate with the hydrogen atoms congregation in Mo/Si boundary.
