Fast neutron dose rate as a function of incident deuteron energy for D+9Be.

The apparatus and techniques employed in measuring the thick target fast neutron dose rate as a function of incident deuteron energy for D+9Be over the energy range 15<or=ED<or=40 MeV are discussed. The resulting data are compared with a summary of previous measurements made at other laboratories. There are significant discrepancies between the two sets of data at the higher energies.
