Prompt Gamma-Ray Activation Analysis: latest results from PSI and future projects for the FRM-II in Munich — •Petra Kudějová¹, Sébastien Baechler², Jan Jolie¹, and Thomas Materna¹ — ¹Institut für Kernphysik, Universität zu Köln, D-50937 Köln, Germany — ²Institut Universitaire de Radiophysique Appliquee, Grand-Prè 1, CH-1007 Lausanne, Switzerland

At the beginning of the year 2004, the Prompt Gamma-Ray Activation Analysis (PGAA) installation, which successfully ran at the Paul Scherrer Institute (PSI), Switzerland, will be mounted and operated at the new Munich research reactor FRM-II, Germany. This new set-up will keep its advantages from experience gained at PSI and in addition will profit from better conditions at the FRM-II and from new improvements. A set of archaeological, geological or other kind of samples can be measured using the automatized measuring system developed for PGA at PSI. With the use of neutron focusing lens, position sensitive PGA can be performed. Example of analysis of 54 roman brooches is presented. A new project in cooperation with cosmochemists concerning systematization in elemental composition of meteorites is discussed.
