Abstract

A magnetically guided slow positron beam with variable energy up to 50 keV has been built in the positron laboratory of CERI (Orléans). The accelerator is coupled with a Doppler broadening spectrometer. A 4μm polycrystalline W foil is used to moderate the positrons. The speed selection of positrons is performed with a 90° elbow. An activity of about 6 μCi was measured on the sample holder with a conventional 60 mCi ²²Na positron source of 6 mm in diameter. We measured the electron momentum distributions in the first micron of heavy ions (Pb, Ar) implanted n-type Ge. Different ion fluences are compared.
