Consortium Seeks to Expand Fundamental Physics Research

Feb 08 2021

The Science and Technologies Facilities Council, (STFC) has provided £7.2m of initial funding to the Atom Interferometry Observatory and Network (AION), an interdisciplinary mission that will harness cold atom technologies to address key issues in fundamental physics, astrophysics and cosmology that can be realised in the next few decades.

The AION consortium, led by Imperial researchers, will enable a ground-breaking search for ultra-light candidates for dark matter – a mysterious substance that makes up 85% of the ‘missing’ matter of the universe – and also pave the way for the exploration of gravitational waves – ripples in spacetime created by huge astronomical events. An interdisciplinary team at STFC’s Rutherford Appleton Laboratory, will be responsible for the design and build of a 10-metre atom interferometer that will advance understanding of dark matter and enable observation of gravitational waves in an entirely new frequency range.

This will be the first large-scale atom interferometer in the UK and will pave the way for larger-scale experiments in the UK in the future. Members of the consortium will also contribute to MAGIS, a partner experiment situated at the Fermi National Laboratory in the USA, networking the two instruments together.

The AION project is a consortium led by Imperial College London and includes the University of Birmingham, the University of Cambridge, Kings College London, the University of Liverpool, the University of Oxford, and the STFC Rutherford Appleton Laboratory.

In addition, the project is in partnership with UK National Quantum Technology Hub in Sensors and Timing, Birmingham, UK, the MAGIS Collaboration, US, and the Fermi National Accelerator Laboratory, US.

The new funding will also establish for Imperial a leading role in large-scale atom interferometry for fundamental physics research, as the AION consortium looks towards possible 100m- and km-scale terrestrial detectors as well as a future space mission.
