Precision measurements of dark matter require precision instruments

anu_beamline_tinted.jpg

With expertise from the ANU in Accelerator Mass Spectrometry (AMS) and experience from ANSTO in precision gamma-ray spectroscopy, we can develop ultra-sensitive radioactivity measurement techniques. Additionally, experts at UWA establish the ultra-precise measurements of frequency and other quantities that are needed for cold dark matter searches.
