Samples and targets for nuclear measurements delivered by CBNM during 1989Funded under: JRC-NUMEAS 4C
CBNM supplied 870 samples to 14 customers during 1989, together with 76 samples in support of the CBNM specific programme. These were mainly thin deposits of actinides, metals and alloys or plastic films. There were also a number of collaborative projects requiring special targets or characterisation. These included the preparation of homogeneous hydrocarbon layers for the investigation of the neutron scattering effect of hydrogen, and the characterisation of the 10B and 6LiF layers by the observation of neutron induced reactions with calibration carried out by IDMS. These layers were used for a remeasurement of the neutron lifetime. Homogeneous U-Pu alloys were prepared for candidate spike materials for U and Pu determinations by IDMS of the undiluted input solutions of reprocessing plants. A metallographic facility for these alloys has been designed and a homogeneity control method by gamma-spectrometry is being developed. CBNM is preparing a range of reference materials for reactor neutron dosimetry. New candidate reference materials include Al-Au and Al-Co alloys and a V-Ti-Fe-Ni-Co alloy for high temperature applications.
