“…In Ref. [9] the relation described in (4) for the lifetime of a carbon foil has been deduced from the first principles of physics of radiation defects and the stress-deformed condition of solid state. It is known that under irradiation in the solid state two kinds of point radiation defects are created -the displaced atoms (or interstitials) and vacancies.…”

“…The numerical values are presented for graphite. Then for the case of nanocrystalline graphite with the size L c 20 A that is characteristic for carbon foils obtained by cracking of ethylene in the glow discharge (GD-foils), the melting point will decrease to 3473 K. Then for GD-foils the resulting formula for calculation of the lifetime can be written as follows [9]:…”

The problems of stripper target behavior in the nonstationary intense particle beams are considered. The historical sketch on studies of radiation damage failure of carbon targets under ion bombardment is presented. The simple model of target evaporation under intensive pulsing beam is supposed. Lifetimes of stripper targets under intensive nonstationary beams can be described by two failure mechanisms: radiation damage accumulation and evaporation of a target. At the maximal temperatures less than 2500 K the radiation damage dominates; at temperatures above 2500 K the mechanism of evaporation of a foil prevails. The proposed approach has been applied to the description of stripper foils behavior in Brookhaven National
