The University of Cambridge is contributing to one of the most far reaching pieces of technology innovation the world of research has witnessed.

It is part of a brains trust that is creating the world’s largest ever optical telescope – the £88 million E-ELT project.

The European Extremely Large Telescope will make huge strides toward our understanding of the Universe, the effects of dark matter and energy and planets outside the solar system.

Its 39 metres diameter mirror will collect 15 times more light than any existing telescope and produce images 16 times sharper than the Hubble space-based telescope.

The investment will ensure UK scientists and engineers are heavily involved in the construction and operation of the telescope and its instruments, set to be the most advanced of its kind. There is also a huge economic payback for the UK.

UK industry has already won £9 million worth of contracts, and that figure is predicted to increase as much as ten fold before 2023 when construction is expected to be completed. The E-ELT is being built in Chile.

The UK instrument programme will be delivered in close collaborations between the University of Cambridge and counterparts at Durham University, the University of Oxford,the STFC’s UK Astronomy Technology Centre in Edinburgh and RAL Space, working with leading international institutes.

The advanced manufacturing challenges presented by the project are providing UK companies with the opportunity to apply for contracts.

A UK technology development centre based in North Wales is delivering prototypes for the primary mirror system, which will consist of 798 hexagonal mirrors each 1.4m wide. This development is aimed at securing a potential €100 million order for UK industry to manufacture the production segments.

David Willetts, Minister for Universities and Science David Willetts said: “This significant investment will ensure the UK plays a leading role in a groundbreaking international project and our world-class research base has access to the latest equipment.

“Not only will this new telescope considerably increase knowledge of the universe, its construction will drive growth and innovation for UK industry. This is why space is one of our eight great technologies.

“To top it off, the advances in technology that will result from this hugely challenging project will be a real asset to the UK and have knock-on effects for other sectors and areas of research.”

The E-ELT will benefit the UK in many ways, says Willetts. Technology developed for astronomy is already being applied across many sectors, including extending the life of artificial knee joints, diagnosing eye diseases, improving the performance of industrial lasers and laser fusion research.

Professor Colin Cunningham, from the Science and Technology Facilities Council’s (STFC) UK Astronomy Technology Centre (UK ATC) who is leader of the UK E-ELT Project Office spelled out its significance.

He said: “UK teams of scientists and engineers have built strong positions over the last few years to enable them to make major contributions to the instruments, telescope engineering and optical systems.

“We expect to lead one of the ‘first light’ instruments and look forward to UK industry making competitive bids for contracts to supply optical devices, detectors, software and engineering services for this challenging project.

“This will culminate in UK astronomers having the opportunity to make breakthrough discoveries in exoplanet research and in understanding the origins and evolution of galaxies.”

The UK has already played a major part in the E-ELT project, leading the development of the science case, developing instrument designs, optical technologies and telescope systems, and developing manufacturing processes.
