Neutron flux parameters at irradiation positions in the new research reactor FRM-II

The new research reactor FRM-II in Garching, Germany, was at full power 20 MW for the first time on 24th August, 2004. Since then, highly thermalized neutrons are available also for neutron activation analysis (NAA). In this report, all essential neutron flux parameters needed to calculate neutron induced reaction rates based on the Hogdahl or Westcott convention are presented for all irradiation positions in this reactor.
