Accelerator-mass spectroscopy with fully stripped 36Cl
Description
The Garching MP tandem-post accelerator-achromator accelerator facility was extended in such way that by it a very backgroundless accelerator mass spectroscopy with fully stripped medium heavy ions was possible. As first applications microscopical amounts of 36Cl (Tsub(1/2)= 301 000 years) were detected. The detection limit lies at 36Cl/CL=4x10-15. In first measurements the method was applied to the age determination of palaeontological samples and to the study of cosmic-radiation induced reactions in the earth crust. (orig.)

Die Garchinger Beschleunigeranlage MP Tandem-Nachbeschleuniger-Achromator wurde so ausgebaut, dass mit ihr eine besonders untergrundfreie Beschleuniger-Massenspektrometrie mit nackten mittelschweren Ionen moeglich wurde. Als erste Anwendung wurden mikroskopische Mengen von 36Cl nachgewiesen (Tsub(1/2)=301 000 Jahre). Die Nachweisgrenze liegt bei 36Cl/Cl = 4x10-15. In ersten Messungen wurde die Methode zur Altersbestimmung von palaeontologischen Proben und zur Untersuchung von hoehenstrahlungsinduzierten Reaktionen in der Erdkruste angewandt. (orig.)
