ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 8.3. The functionality has changed, but the content remains the same.

ANSTO Publications Online is a digital repository for publications authored by ANSTO staff since 2007. The Repository also contains ANSTO Publications, such as Reports and Promotional Material. ANSTO publications prior to 2007 continue to be added progressively as they are in identified in the library. ANSTO authors can be identified under a single point of entry within the database. The citation is as it appears on the item, even with incorrect spelling, which is marked by (sic) or with additional notes in the description field.

If items are only held in hardcopy in the ANSTO Library collection notes are being added to the item to identify the Dewey Call number: as DDC followed by the number.

APO will be integrated with the Research Information System which is currently being implemented at ANSTO. The flow on effect will be permission to publish, which should allow pre-prints and post prints to be added where content is locked behind a paywall. To determine which version can be added to APO authors should check Sherpa Romeo. ANSTO research is increasingly being published in open access due mainly to the Council of Australian University Librarians read and publish agreements, and some direct publisher agreements with our organisation. In addition, open access items are also facilitated through collaboration and open access agreements with overseas authors such as Plan S.

ANSTO authors are encouraged to use a CC-BY licence when publishing open access. Statistics have been returned to the database and are now visible to users to show item usage and where this usage is coming from.

    First βNMR results on SRF samples at TRIUMF
    (JACoW Publishing, 2021-06-27) Thoeng, E; McFadden, RML; Kolb, P; Junginger, T; Asaduzzaman, M; Laxdal, RE; Karner, VL; Fujimoto, D; Chatzichristos, A; Ticknor, JO; Adelman, JR; Dehn, MH; Levy, CDP; Li, R; McKenzie, I; Stachura, M; Dunsiger, SR; Morris, GD; McFarlane, WA; Kiefl, RF; Cortie, DL
    The βNMR (β-detected nuclear magnetic resonance) facility at TRIUMF offers the possibility of depth-resolved probing of the Meissner state over the first 100 nm below a sample surface. The measurement can give the attenuation of the applied magnetic field, as a function of depth. The technique can be especially important when probing layered systems like the dirty/clean S-S (superconductor-superconductor) bilayer and S-I-S (Superconductor-Insulator-Superconductor) structures. The TRIUMF SRF (Superconducting RF) group has recently completed first measurements at beta-NMR on Nb samples with various treatments. The results and method will be reported.

    An annually resolved stalagmite record of fire frequency for the last 250 years in south west Australia
    (European Geosciences Union (EGU), 2023-04-25) McDonough, LK; Treble, PC; Baker, AA; Borsato, A; Frisia, S; Campbell, M; Nagra, G; Coleborn, K; Gagan, MK; Zhao, J; Paterson, DJ
    Stalagmites provide records of past changes in climate, vegetation, and surface events, which can be identified through variability in their chemical composition over time. This variability is the result of changes in surface environmental properties, which are reflected in the physical and chemical properties of the water that percolates into the cave, ultimately affecting the composition of the speleothem calcite. Wildfires have the potential to alter soil properties and soluble element concentrations. Consequently, stalagmite compositions have been shown to respond to increases in soil nutrients, trace metal concentrations, and changes in soil/karst bedrock hydraulic conductivity. It is, therefore, likely that stalagmites, and particularly those grown in shallow caves for which transmission of the surface signal is rapid, capture the environmental effects of wildfires in their chemical and physical properties. We analysed a stalagmite from a shallow cave in a region known to be affected by wildfires in south-west Western Australia. Fire proxies were assessed using a multi-proxy approach. This includes water isotopes via stable-isotope ratio mass spectrometry and trace element analyses via synchrotron X-ray fluorescence microscopy and laser ablation inductively coupled plasma mass spectrometry. This approach shows that the timing of known fire events coincided with a multi-proxy response in stalagmite chemistry, including increased concentrations of phosphorus, copper, aluminium, lead, and zinc, which are interpreted to be derived from leaching of ash from burned vegetation above the cave. We also identified lower and less variable peaks in phosphorus concentrations during the pre-colonisation period, suggesting that Indigenous land management resulted in more frequent but low intensity burning. This contrasted with less frequent but more intense fires associated with post-colonisation land-management. A particularly large paleo-fire identified in 1897 appears to coincide with a peak in 𝛿18O, interpreted to have resulted from evaporation of sub-surface water during the heat of the fire. This large fire was preceded by a multi-decadal dry period identified by trace element proxies. The intensity of the 1897 fire was then exacerbated by the combination of a multi-decadal drought and a transition away from cultural burning practices by Indigenous Australians, which resulted in build-up of vegetation and dry combustible material on the forest floor. This research is a world-first demonstration of fire events recorded in stalagmites and shows their potential to provide accurate records of both fire frequency intervals and changes in climate. Further records of past fire events from stalagmites will help to understand how past fire regimes have varied with climate, land-use change and colonisation, and will help to better guide land management practices in the future. © Author(s) 2023.

    Characterization of a novel large area microdosimeter system for low dose rate radiation environments
    (Elsevier, 2021-06-21) Pan, VA; Pagani, F; James, B; Bolst, D; Peracchi, S; Vohradsky, J; Pogossov, A; Guatelli, S; Petasecca, M; Lerch, MLF; Prokopovich, DA; Boardman, DA; Perevertaylo, VL; Williams, AG; Werczynski, S; Inaniwa, T; Matsufuji, N; Jackson, M; Tran, LT; Rosenfeld, AB
    A feasibility study is presented on a newly developed Microdosimetry system named Octobox, for its application in low dose rate, mixed radiation environments. A full characterization of the device was performed at the Heavy Ion Medical Accelerator in Chiba (HIMAC), Japan, out-of-field of various heavy ion radiation fields — 290 MeV/u 12C, 230 MeV/u and 490 MeV/u 28Si and 400 MeV/u 20Ne ions, as well as a low dose rate 222Rn environment at the Australian Nuclear Sciences and Technology Organization (ANSTO). The device was shown to collect adequate statistics in a short period of time when compared to the MicroPlus probe with a single microdosimeter, while accurately measuring microdosimetric quantities and the corresponding average quality factor (Q) and dose equivalent (H) of the mixed radiation field. Good agreement of the microdosimetric spectra was also shown with Geant4 simulations for all presented ion fields. Based on the findings in this study, the Octobox is capable of being applied in mixed, low dose rate, radiation environments such as those encountered in space and aviation, as well as in underground mines for radiation protection purposes. © 2021 Elsevier B.V

    Characterization of CdMnTe radiation detectors using current and charge transients
    (IOP, 2013-07) Rafiei, R; Reinhard, MI; Sarbutt, A; Uxa, S; Boardman, DA; Watt, GC; Belas, E; Kim, KH; Bolotnikov, AE; James, RB
    Charge transport characteristics of Cd0.95Mn0.05Te: In radiation detectors have been evaluated by combining time resolved current transient measurements with time of flight charge transient measurements. The shapes of the measured current pulses have been interpreted with respect to a concentration of net positive space-charge, which has resulted in an electric field gradient across the detector bulk. From the recorded current pulses the charge collection efficiency of the detector was found to approach 100%. From the evolution of the charge collection efficiency with applied bias, the electron mobility-lifetime product of μnτn = (8.5 ± 0.4) × 10−4 cm2/V has been estimated. The electron transit time was determined using both transient current technique and time of flight measurements in the bias range of 100–1900 V From the dependence of drift velocity on applied electric field the electron mobility was found to be μn = (718 ± 55) cm2/(V.s) at room temperature. © 2013 Chinese Institute of Electronics

    Elucidation of atomic and magnetic structures of Al3+-doped Li-ferrite (LiFe5O8) compounds
    (Elsevier, 2025-07) Inckemann, S; Park, SH; Arauzo, A; Avdeev, M
    Chemical stress for structural deformation i , denoted as Li60Al40, and, denoted as Li50Al50, was achieved by introducing into α- known as a high-temperature multiferroic. These new solid solution compounds crystallize in the tetragonal space group P43212. Their magnetic spin arrangements at 300 K could be determined in the magnetic space group P4321 using high-resolution neutron powder diffraction (HRNPD) data. Within the experimental uncertainty in HRNPD, the magnetic moments of ions within in the B-sublattice are arranged along the crystallographic c axis and antiparallel to those of in the A-sublattice. In comparison to the Fe-rich Li60Al40, the Fe-poor Li50Al50 shows a stronger dilute effect for the higher Li content at the octahedral site Fe1b. The dilute effect is associated with the lowering of both saturation magnetization and. On the other hand, Li50Al50 shows large electric dipole moments in the strong distorted and polyhedra. © 2025 The Authors. Published by Elsevier Inc.
