Frequency stabilisation in the Extremely High Frequency band. All precision communication and measurement systems (i.e. radar and navigation) rely on high quality oscillator technology. Any improvement in oscillator performance has a direct impact on the performance of the system and hence is of potential economic benefit. This project will realise the most stable frequencies ever produced in the underused Extremely High Frequency band, which is also important for space communications and naviga ....Frequency stabilisation in the Extremely High Frequency band. All precision communication and measurement systems (i.e. radar and navigation) rely on high quality oscillator technology. Any improvement in oscillator performance has a direct impact on the performance of the system and hence is of potential economic benefit. This project will realise the most stable frequencies ever produced in the underused Extremely High Frequency band, which is also important for space communications and navigation technology. System enhancement will include, better angular resolution, higher bandwidths, faster transmission rates and narrower beam widths without the susceptibility of absorption apparent from the optical domain.Read moreRead less

Summary
High performance clock facility for new-generation radar, imaging, measurement and radio-astronomy applications. At the heart of critical modern technologies (e.g. communications, navigation, radar) lies a high quality oscillator that generates an ultra-pure signal: it is this device that determines the overall system performance. The proposed facility will deliver breakthrough portable technology to improve the performance of these crucial technologies.

This project is to continue the development of novel frequency standards in collaboration with some of the best research institutes in France funded by the French Space Agency (CNES). With the advent of the International Space Station and new atomic clocks, the physics community is embarking on an experimental program that will make use of the microgravity environment of space. Combined with the new improved timing it will be possible to perform new experimental tests of general and special relativity, tests for drifts in the fine structure constant and tests for a preferred direction of the speed of light at unprecedented sensitivity.Read moreRead less

Dark matter is a fundamental component of the universe yet the nature of its composition is still unknown. There is growing evidence that it is comprised of axions, a low energy, weakly interacting particle. The precision measurement tools developed by this project will have the potential to contribute both to the economy, via commercialisation, and to national security, via future applications to radar, communication and the development of engineered quantum systems.Read moreRead less
