Radiation Damage in Metals

Thermal effects in 10keV Si PKA cascades in 3C–SiC

“…Our simulations used the following multiple-phase timestep procedure, based on the phases of cascade formation described in [1,26]. We verified this procedure by checking the maximum system velocity at 100 timestep intervals to ensure that the maximum displacement in a given timestep was less than 1/5 of the nearest neighbor distance.…”

Concentration of radiation displacement defects in BSO and BGO crystals irradiated by electrons or neutrons

“…For fast neutron irradiation the elastic scattering of neutrons on nuclei of matter was described as scattering of hard spheres [8].…”

“…The present work is devoted to the calculation of the RDD concentration in BGO and BSO crystals as a function of electrons and neutrons energy according to the atom-atom collision cascades model [8] (based on the assumptions of the Kinchin-Pease binary collision model [9]) by using a Monte-Carlo method.…”

Concentration of Radiation Displacement Defects in Complex Oxide Crystals upon Energy of Particle

“…For fast neutron irradiation the elastic scattering of neutrons on nuclei of a matter was described as scattering of hard spheres [12]. In order to calculate the cascade functions in both cases computer simulation of the atom-atom collision cascades by the Monte-Carlo method was used.…”

“…On the other hand, there are few programs simulating atomic collisions in crystalline targets using the binary collision approximation (for example MARLOWE [11]). This work is a theoretical continuation of the work [1] and is devoted to the simulation of the radiation defects accumulation in the Y 3 A l5 O 12 , YAlO 3 , Gd 3 Ga 5 O 12 , LiNbO 3 as a function of particle (electrons, neutrons) energy according atom-atom collision cascades model [1,12].…”
