The positrons are produced by pair production from high energy γ-rays after the capture of thermal neutrons in cadmium. The pair production itself takes place in a stack of layers, each consisting of two concentric rings made of tungsten foils. The source is placed in a beam tube at the Research Reactor Munich at Garching. From first experimental data, we can extrapolate an intensity of 2 × 108 slow positrons per second and a spot size of less than 26 mm.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Luft- und Raumfahrttechnik, LRT 2 - Institut für angewandte Physik und Messtechnik, Professur: Dollinger, Günther}, }
