Abstract: A low-energy positron beam apparatus has been designed and constructed. The beam can deliver a current of 4X 104e+/s to a target when a 7.3mCi 22Na source is used. The energy range,available at present is between 25eV and 16keV. We have applied it to study initially on the dynamic process of WSix film formation and on the distribution defects produced by N+ ion in nickel.
