Conf. on Positron Annihilation, Gent, 1988 (World Scientific, Singapore, 1989) p. 15] at the 65 MeV linac, which provides intense beams of slow positrons in the energy range between some eV and 100 keV is presented shortly. New experimental results for positron remoderation and of relative K/L cross-section measurements are given.
