D. Peter Siddons is the leader of the Detector Development group at the Brookhaven National Laboratory’s National Synchrotron Light Source (NSLS). His development efforts are focussed on advanced instrumentation for x-ray synchrotron radiation experiments.
He has been responsible for the collaboration between the CSIRO and Brookhaven National Laboratory in the development of the Maia x-ray microprobe elemental imaging system — a high-throughput x-ray fluorescence detector system which – when combined with a focused x-ray source such as the Australian Synchrotron’s x-ray fluorescence microprobe (XFM) beamline – is able to produce high-definition, quantitative elemental images with microscopic or nanoscopic detail in real-time.
Maia was developed to meet the challenge to capture spatial detail over four orders of magnitude from the micron scale to the scale of a few centimetres in complex natural and manmade samples encountered in research using the synchrotron in the biological, geological, materials and environmental sciences, medicine and cultural heritage.
Recently, Maia won a prestigious R&D 100 Award, presented by the US-based R&D Magazine, ‘to salute the 100 most technologically significant products from around the world introduced into the marketplace in the past year’.
