Die vorliegende Arbeit umfasst zwei Teilgebiete der elementaren Reaktionen am HADES-Detektor der GSI. Ein Aspekt sind die apparativen Entwicklungen zur Optimierung des Pionenstrahls. Im zweiten Teil werden Ergebnisse eines Proton-Proton Experiments zur Bestimmung des elektromagnetischen Übergangsformfaktors des Eta-Mesons dargestellt. Der für die Pion-Kern Experimente benötigte Pionenstrahl wird durch den Beschuss eines Beryllium-Targets mit einem Schwerionenstrahl erzeugt. Nachteil eines Sekundärstrahls ist die schlechte Emittanz, da die im Produktionstarget erzeugten Pionen eine breite Impulsverteilung besitzen und über eine breite Winkelverteilung emittiert werden. Daneben ist die Intensität des Strahls um Größenordnungen kleiner als die...
