Fast neutron research:

In a cooperation with Los Alamos National Laboratory, going back to the year 1969, neutron and gamma ray data both for basic physics and applied purposes are being measured and evaluated. The data reduction and evaluation is done at the institute.

More recently, in a cooperation with the University of Cape Town neutron experiments for applied purposes are made at the National Accelerator Centre of South Africa in Faure.


 High-lights of recent years:

  1. Invention of a nuclear method for the identification and possibly the detection of hidden explosives. This invention is based on the fact that as a rule, at least 1 out of 4 atoms in an explosive is hydrogen. It was shown experimentally that as little as 130 g of Urea can be measured very easily when covered with 14 cm of sand. So it is likely that mines with only 100g explosive with a cover of up to 30 cm of soil can be detected. This sensitivity is far superior to that of any other nuclear method in use or proposed. A vehicle based prototype device with a total mass of less than 600 kg is proposed at a cost of less than 1 million $.
  2. Application of nuclear techniques in planetary research (Mars). Just recently first results on the abundance of water on Mars have become available.
  3. Further development of a package of computer codes (DROSG-2000) for the calculation of kinematic properties and predictions of neutron yields of accelerator-based monoenergetic neutron sources as a calculational backbone for the application of fast neutrons in medicine, humanitarian applications and technology. This package now includes 59 source reactions.
