Radiation damage in TiO x at high current density

Observations of beam damage under high-current-density irradiation in three forms of titanium oxide are presented. The three forms: TiO2, Ti2O3 and TiO, have widely differing electrical conductivities but all appear to be damaged by the same mechanisms. The results are discussed in terms of a previously reported model which suggested that only ionic insulators should be susceptible to this type of damage.
