The Shanghai Synchrotron officially opened its doors last week, making it the world’s newest synchrotron facility. Although that means the Australian Synchrotron is no longer the new kid on the block, I’m proud to say that we, along with many other facilities, assisted the Shanghai Synchrotron. It was in much the same way that other older synchrotrons helped us get started.
One of the key reasons why the international synchrotron community is so strong is that we share our knowledge. Come September 2009, we’ll be doing it again, only this time the party’s in Melbourne for the world’s biggest synchrotron science and instrumentation conference: SRI2009.
It’s an incredible opportunity for Australians interested in any aspect of the production and application of synchrotron radiation.
Guest speakers include Dr Paul Tafforeau, a paleontologist who is bringing ancient history to life – not literally, of course – by using the European Synchrotron Radiation Facility to examine insects preserved in amber.
And there’s a whole section devoted to the next generation of light sources, led by ex-Melburnian Prof Henry Chapman from DESY (the German electron synchrotron), who is helping to open up a new era in x-ray imaging that will deliver detailed structures of single molecules.
Looks like a good meeting!
The Federal Budget had good news for the Australian Synchrotron and its users: $36.78 million for key onsite infrastructure additions and improvements, including onsite accommodation for users.
Over the next few years we will build a National Centre for Synchrotron Science building to house the synchrotron’s user office, a cafeteria, 400-seat auditorium, seminar rooms and office space, as well as catering for educational activities, exhibitions and community engagement.
A separate user accommodation building will contain 50 rooms with communal kitchen and lounge facilities.
Other buildings and extensions to the main synchrotron building will house workstations for staff, ‘hot desks’ for users, and technical support laboratories.
Beamtime submissions for the 2009/3 round (September – December 2009) will open on 21 May 2009 and close on 17 June 2009.
Key dates for 2009 beamtime submissions are listed here.
If you would like to discuss your ideas for future beamline proposals with the beamline scientists at the Australian Synchrotron, please allow plenty of time.

The Australian Synchrotron's medical and imaging facility will be upgraded to become the most advanced instrument of its type in the world.
The facility has been awarded $13.2 million from the National Health and Medical Research Council (NH&MRC) and $1.5 million from the Victorian Government for a major expansion that will position Australia at the forefront of this field.
Scheduled for completion in 2012, the upgraded facility will deliver the world’s biggest x-ray beam: 60 centimetres wide and five centimetres high. It will support the development of a new generation of techniques for medical imaging and radiotherapy and new approaches to clinical practices, therapies and drug evaluation.
Researchers will use the facility to obtain high-resolution images of cells and tissues, and use specialised markers to follow the movement of cells through tissues and organs in real time. They will also study how radiation interacts with cancer cells and healthy tissues and use their findings to develop better radiotherapy treatments.
Daniel Häusermann, the synchrotron’s principal scientist – imaging and medical therapy, said the new funding was due to the efforts of a consortium of research organisations and users supported by the Australian biomedical and medical research communities.

The SAXS/WAXS beamline at the Australian Synchrotron is at the forefront of a potential new non-invasive test for breast cancer.
The promising test, which is soon to become commercially available, is being developed by Fermiscan Holdings Ltd, a Sydney-based medical research company. It is based on an Australian discovery that scalp hair from breast cancer patients shows a unique x-ray diffraction pattern – an additional ring in the apha-keratin diffraction region – which can be detected using an undulator small angle x-ray scattering beamline.
A large-scale Australian clinical trial completed in 2008 found the Fermiscan test had an accuracy of 77 per cent compared to mammography and tissue biopsy. Its accuracy increases when dyed and permed hair samples are eliminated.
Fermiscan researchers are using the SAXS beamline in Melbourne to commercialise the new test. They have also conducted analyses at synchrotrons in the US and Europe, but the Australian Synchrotron offers significant cost and logistical benefits as well as a world-class SAXS beamline.
Breast cancer affects one in eight Australian women and is the most common invasive cancer diagnosed in females worldwide.The new test could be particularly useful for screening women under 50, whose breast tissue can be too dense for mammography. The technique may also have potential as a diagnostic tool for other diseases.
Queensland company Mesaplexx is using the Australian Synchrotron to develop the next generation of microwave filters for improved mobile phone signal quality and data bandwidth.
The ceramic filters are used in microwave communications systems. Mesaplexx’s first microwave filter is currently being trialled by several telecommunications manufacturers.
In such a competitive field, quick results are essential. That’s why Mesaplexx materials scientist Toru Yamashita and Mesaplexx consultant solid-state scientist John Barry recently visited the Australian Synchrotron to use x-ray absorption fine structure (XAFS) on the x-ray absorption spectroscopy beamline. XAFS will enable them to gain a more detailed understanding of how the localised atomic structure of the ceramics, particularly the titanium-oxygen bonds, responds to changes in manufacturing conditions – and provide valuable clues about how to produce better ceramics.
Mesaplexx had previously used the synchrotron’s powder diffraction beamline to determine the ‘unit cell’ – the primary building block – of the polycrystalline ceramic structure.
The synchrotron findings will be combined with other test results and computer models to provide insights into the relationship between ceramic structure and performance.
Improved microwave filters could boost data transfer speeds and improve reliability in existing telecommunications networks or increase the range of wireless communications networks being established in new markets such as China and India.
“The Australian Synchrotron is very impressive,” John said. “It’s equal to any overseas user facility, it’s much better organised than some, and the equipment is top rate.”
Beamline scientist Anton Maksimenko has released the first public version of an open-source software package to enable synchrotron imaging data (from parallel beam geometry) to be turned into three-dimensional computed tomographic (CT) images.
The CTAS software package can also be used for tomosynthesis reconstruction or diffraction enhanced imaging (DEI) processing of pairs of images.
Originally devised as part of Anton’s PhD, the software draws on his experience at synchrotrons in Japan and Australia. It was developed on Linux operating systems and has also been successfully ported to other platforms.
The package is immediately available and contains many ready-to-use features, but Anton warns prospective users that it still contains a few bugs. He is keen to hear from people interested in using the software or testing it and helping to extend the range of applications. In accordance with open software principles, the software is freely available for people to use, modify and redistribute.
Anton is continuing to develop his software for use on the imaging and medical (IM) beamline at the Australian Synchrotron.
The Australian Synchrotron is developing a new website to meet the evolving needs of its users and other important audiences. We have selected a web designer by competitive tender and we hope to show you a sample of the new website design in the next edition of Lightspeed. Our aim is to have the website available to people attending the SRI09 conference in Melbourne in September this year.
