Dependence of F-center accumulation in NaCl crystals on the proton beam intensity

Particle track phenomena and radiation power effects at the formation of radiation defects in ionic crystals

“…At V т = 1.3·10 -14 cm 3 , ρ = 2.7 g/cm -3 , τ р1 = 10 -8 s, τ g = 10 -11 s, and Е = 200 keV, we have W 0 = 10 13 Gy/s. This power is close to the threshold of brittle fracture of crystals [14]. For τ g = 10 -11 -10 -8 s, W 0 = 10 13 -10 10 Gy/s.…”

“…Figure 1 shows a qualitative curve of defect relaxation in the track according to Eq. (14). It is particularly remarkable that the sharp maximum of the curve transforms into a plateau at τ g << τ р1 .…”

“…To describe the radiation power and kinetic effects, D. I. Vaisburd et al [13,14] developed a track approach taking the proton beam irradiation of ionic crystals as an example. We extended this method to the case of electron irradiation of materials.…”

“…The other terms in Eq. (14) describe different stages of the Frenkel-pair destruction. If the pair components are within the instability zone, the losses of the complementary defects in the monomolecular process are described by an exponential dependence exp…”
