“…Decay, activation, and displacement cross-sections are typical results of benchmark experiments that have been published since the 1990s (e.g. [100,101,[101][102][103][104][105][106][107][108][109][110][111][112][113]). Beside the three above mentioned topics, the main field in which irradiation and plasma interaction with tungsten come into play is nuclear fusion.…”

“…The interaction of high energy nucleons with materials produces recoil atoms with kinetic energies considerably exceeding the present maximum energy of MD simulations [3,4]. For an energetic ion moving in the material the simulation of the atomic collision was performed by BCA up to a certain "critical" energy (T crit ) of the ion.…”

Abstract.A method combining the intranuclear cascade evaporation model, the binary collision approximation model and the method of molecular dynamics is proposed for the calculation of displacement cross sections for structural materials irradiated with intermediate and high energy particles. Calculated displacement cross sections are compared with experimental data for copper irradiated with 1.1 and 1.94 GeV protons. Calculations up to the proton energy 0.1 TeV are discussed.

“…However, * corresponding author; e-mail: djaafri_aek@yahoo.fr there have been very few reports on the damage production in tantalum [14][15][16]. The displacement cross-section for tantalum irradiated with protons and neutrons at energies up to 1 GeV has been investigated by Broeders and Konobeyev [14,15].…”

We have investigated the point defect distributions in tantalum under irradiation by means of the Marlowe code based on the binary collision approximation. The study is carried out by simulating displacement cascades initiated with primary knock-on atom energies ranging from 5 to 20 keV. The Molière, Born-Mayer and average modified Lenz-Jensen potentials are used to describe the interactions between tantalum atoms. We have examined the creation of damage, the spatial defects distribution, and the vacancy clustering in tantalum. The results show that with an appropriate recombination radius, less than 16% of the created defects constitute permanent Frenkel pairs. Spatial configuration of defects indicates a separation between the two point defect types, vacancies and interstitials. The Molière potential favors the production of a greater number of displaced atoms and the development of voluminous cascades more than the other potentials. The cascade volume distributions deviate clearly from a Gaussian distribution. They are large and very stretched toward higher volumes for all used potentials. Only small vacancy clusters are formed in tantalum under irradiation and about 41% of the produced vacancies are considered as isolated
