“…A neutron generator based on the deuteron-triton (D-T) reaction has many applications in measurement cross-section for nuclear reactions, fusion reactor material irradiation, neutron activation analysis, and other industry fields. [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 ).…”

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.

“…Therefore neutronics integral experiments with breeding blanket mock-up are an important research activity to validate the evaluated crosssection data files so that cross-section files can be upgraded and uncertainty in TBR due to cross-sections can be reduced. Several neutronics benchmark experiments with blanket mock-ups are reported in the literature for different breeding blanket concepts [2][3][4][5][6][7][8][9]. India has proposed Lead-Lithium cooled Ceramic Breeder (LLCB) concept of breeding blanket for in situ tritium breeding in its DEMO reactor [10].…”
