At the CBNM, besides classical techniques like electrospraying, spray painting and electrolysis, high quality actinide deposits are prepared by vacuum deposition of actinide fluorides. This is, however, dependent on the preparation of high quality actinide fluoride powders without water residue. This technique is used to prepare targets for cross section measurements, for fission fragment studies and also for targets used as fission foils. In this case, high accuracy characterisation is obtained by low geometry alpha-counting and IDMS calibration. Similar techniques are used to prepare certified reference deposits of 6LiF and 10B for absolute neutron flux measurements. Since many deposit requests are carried out on thin foils, important development work involving the preparation of very thin polymide foils is taking place.
