The Berlin cold neutron source
Description
The Hahn-Meitner-Institut (HMI) has operated research reactors since July 1958. The 50 kW Water-Boiler-Reactor BER-I was in service mainly for isotope production, activation analysis and the study of radiation effects until 1971. The 5 MW Swimming-Pool Reactor BER-II became critical in 1973 and was increasingly used for beam-tube experiments until 1985, when an upgrading program was started to meet the increasing demands of the users for higher neutron intensities and more advanced experimental facilities. Increase of power level from 5 to 10 MW, reduction of core size and a fixed Beryllium-reflector with optimal fitting of the beam-tube noses to the reflector flux peak will improve the beam intensity up to a factor 10. In addition, the Berlin CNS has been installed. The basic design-, engineering- and safety criteria are described
