Study of defect and new phase accumulation by proton-excited characteristic X-ray under irradiation of tungsten monocrystals

Consideration is given to results of studying peculiarities of radiation defect accumulation for the case of monocrystal tungsten ion irradiation by nitrogen and neon at different ion current densities. Implantation was conducted at energies E=150 keV and two ion current densities - J=2 and 20 μA/cm in random-direction. It is shown that nitrogen atoms promote radiation defect accumulation and lead to involvement of intercascade processes in secondary defect formation with achievement of high N+ doses. 3 refs.; 1 fig
