Abstract
A new electrostatic positron beam for Doppler broadening measurements in the near surface layers has been constructed and tested in the Trento laboratory. The beam energy is tuneable from 50 eV to 50 keV. The diameter of the beam spot at the sample is two mm FWHM, when a commercial 22Na source of 3 mm in diameter is used. The beam could be easily upgraded to become a microbeam. The apparatus is described and the preliminary tests are presented.
