Abstract

An initial study of high flux rate implantations of nickel ions into polycrystalline titanium has been made using the Harwell Ion Separator, with doses of 40 keV ions up to a few × 1018ions/cm2, at flux rates up to 4.4 × 1014 ions/cm2 sec (∼70 μA/cm2). Penetration depths approaching 1 μm have been observed (to be compared with a Lindhard stopping depth of ∼2 × 10-2 μm), with a very high retention of Ni ions (up to ∼ 90% of the dose). The profiles of implanted nickel appear not to be compatible with observed thermal diffusion co efficients, but could be compatible with a radiation enhancement.
