ON THE ENERGY-DEPENDENCE OF BUBBLE DAMAGE NEUTRON DETECTORS

Energetic dependence of bubble damage neutron detectors, manufactured by Bubble Technology Industries Inc. (Canada), was studied. The detect ors were exposed in neutron fields derived from a Cf-252 source as wel l as those from behind the shielding of the phasotron of the Joint Ins titute of Nuclear Research at Dubna, Russia. BD-100R detectors with tw o different nominal sensitivities were tested. It was discovered that their response probably does not depend on a neutron energy between 0. 1 and about 20 MeV. It seems, however, that their sensitivity to highe r energy neutrons is reduced.
