A 6 MeV industrial electron linac with 0.2 mA average current will be installed in December 2007 in CEA-Saclay. Equipped with a tungsten target and moderator, it is aimed at producing rates of order 10 8 s-1 slow positrons. This setup is part of a project to demonstrate the feasibility of an experiment to produce the Hbar+ ion for a free fall measurement of Hbar. The energy is below the neutron activation threshold. Its small size and cost could be of interest for a university laboratory or industry, and could be envisaged as a replacement source for the antihydrogen experiments at CERN.
