[en] Since 1976, 30 laboratories have submitted 85 samples of ⁶⁰Co to the International Reference System (SIR) for activity comparison at the Bureau International des Poids et Mesures (BIPM), with comparison identifier BIPM.RI(II)- K1.Co-60. Recently, the PTB (Germany), the NIST (United States), the SMU (Slovakia), the BARC (India), the LNE-LNHB (France), the POLATOM (Poland), the ENEA-INMRI (Italy), the NPL (United Kingdom), the LNMRI-IRD (Brazil), the NMISA (South Africa) and the ANSTO (Australia) participated in the comparison and the key comparison reference value (KCRV) has been updated. The degrees of equivalence between each equivalent activity measured in the SIR and the updated KCRV have been calculated and the results are given in the form of a table. A graphical representation is also given. (author)

[en] The ANSTO plan of December 1987 defines the corporate environment of HIFAR. Amongst other things, the plan emphasised HIFAR as a key national facility, and identified HIFAR operations and facility upgrading as activities within an outward looking nuclear technology program. This paper outlines the present operation of HIFAR within that program

[en] The 1990-1991 Program of Research reflects the fundamental changes within the Australian Nuclear Science and Technology Organization (ANSTO) over the past three years as it has oriented itself towards being a more commercially driven organization, an organization responding to market demands and pressures. From July 1, 1990 several key projects have been linked together in the new Industrial Technology Program. The Program encompasses projects that have real potential to earn revenue for ANSTO and make measurable improvements in efficiency and productivity for Australian companies. The Isotope Technology project is researching and transferring to industry radioisotope technology for tracing the effectiveness of plant processes, the movement of materials within blast furnaces and leakages and outages in plant pipework. The two important newcomers are the Quality Technology Centre and the Safety and Reliability group. Details about project leaders, project titles and objectives are provided. ills

[en] Full text: Multilayers of doped Silicon are the heart of the diodes and transistors which form the basis for virtually all modern electronics. With a rapidly impending need for more energy efficient computers, it is interesting to see what can be done with multilayers of more exotic starting materials. The superconductor sandwiches we study are thin-film multi-layers of the high temperature superconductor YBa₂Cu₃O₇ and the perovskite manganite Nd_0.65(Ca_0.7Sr_0.3)_0.35MnO₃. We discovered that a highly unusual superconducting state could be induced in the YBa₂Cu₃O₇ by tuning the properties of the manganite. It remains to be determined precisely how the manganite can so radically effect the superconducting state in the adjacent layer. Here, we discuss our current polarised neutron reflectivity (PLATAPUS) and Bragg scattering (TAIPAN) work to investigate the role of the manganite’s magnetism and magnetic ordering in causing the unusual properties of the superconductor sandwiches.

[en] From 1 July 1988, the research activities of ANSTO have reorganised into five programs: advanced materials; applications of nuclear physics; environmental science; applications of radioisotopes and radiation; biomedicine and health. This structure not only groups the main research activities but also identifies the underpinning of ANSTO's commercial activities. This document describes the projects to be undertaken in the 1988-89 financial year. Each project in a particular program area is defined in terms of background, objective, recent work and achievements, work planned, resources and the project manager is identified. Research is also undertaken in areas of the operational activities of the organisation and these also are detailed

[en] Full text: The Australian Bragg Centre construction begins next year, however the planning for an integrated national particle therapy cancer treatment plan has already commenced. This includes comparative photon/proton planning, a national MDT and clinical database leading to better decisions and data driven research. Clinical trial collaboration has begun with many overseas centres. Non clinical research themes of biotech development, imaging, eye treatment and micro beam technology will be discussed along with discussion of how all the scientific community can engage and propose areas of research. There will be discussion on how we will assess projects for benefit to patients and the Australian Bragg Centre and how we can collaborate on business plans for proposals. (author)

[en] During the period under review, the Australian Nuclear Science and Technology Organization (ANSTO) sought to identify the most appropriate commercial vehicle, from joint ventures to licensing agreements, to transfer its technology to private enterprise. That vehicle, the Industrial Technology Program covers projects such as neutron radiography, safety and rehability studies and quality assurance. The Annual Report outlines the main research projects, the people involved and their achievements as well as future trends. ANSTO's external revenue reached 24% of recurrent appropriation, well on the way of the 30% target by the end of the 1992-1993 financial year. tabs., ills
