Research Highlights for Oxford Centre for High Energy Density Science (OxCHEDS)

The Oxford Centre for High Energy Density Science (OxCHEDS) has led the first ever experiment on the newly-commissioned High Energy Density Science end-station at the European XFEL. Professor Gianluca Gregori was joint PI, and he, Justin Wark, AWE academic visitor Andy Comley, and Oxford students and postdocs were part of the team that included collaborators from SLAC, LLNL, and XFEL.

The sixth annual meeting of the Oxford Centre for High Energy Density Science (OxCHEDS) took place on 18th and 19th of March at Trinity College, Oxford attracting over 40 attendees from AWE and the University of Oxford.

Despite the weather over 1,000 members of the general public visited the ‘Stargazing Oxford’ Event on Saturday 26th January in the Denys Wilkinson Building, Oxford, with one youngster overheard saying they wanted to stay forever! The event covered an enormous range of space-based activities included 15-minute talks from academics within the University of Oxford Physics department such as ‘A history of the Universe for those short on time’ and ‘How to discover a planet’, an inflatable planetarium, ‘astro-crafts’, and of course what stargazing was possible through the clouds!

Temperature measurement is the ‘elephant in the room’ for work on laser compressed solids. Very few in-situ nanosecond temperature measurement techniques currently exist, and those that do either fail at the modest temperatures reached in dynamic compression (e.g. pyrometry) or show large error bars, often order 50% (e.g. EXAFS). As a result, the temperature of shocked condensed matter is generally inferred from theory.

The fifth annual meeting of the Oxford Centre for High Energy Density Science (OxCHEDS) took place on 19th and 20th of March at Trinity College, Oxford attracting 40 attendees from AWE and the University of Oxford.

On the 30th August Orion featured at a special exhibition at the Science Museum London: Science Museum LATES. We were invited to participate by the Royal Society following on from the recent Royal Society event. The stand was designed and manned in collaboration with Imperial College London, through CIFS (Centre for Inertial Fusion Studies), and the University of Oxford, through OxCHEDS (Oxford Centre for High Energy Density Science).

The ‘How to Make a supernova’ stand generated a lot of interest and some of this was channelled through social media via a dedicated Twitter account @MakeASupernova and through the Royal Society website which can be found here. The exhibit also had its own webpage at: www.physics.ox.ac.uk/supernova.

After months of planning researchers from AWE, the University of Oxford and Imperial College London presented their exhibit ‘How to Make a Supernova’ at the Royal Society Summer Science Exhibition 3rd–9th July 2017.

The exhibit focussed on how Orion has been used for academic access experiments for laboratory astrophysics led by Gianluca Gregori, Oxford, and Francisco Suzuki-Vidal, Imperial.

The fourth annual meeting of the Oxford Centre for High Energy Density Science (OxCHEDS) took place on 27th and 28th of March at Trinity College, Oxford attracting over 40 attendees from AWE and the University of Oxford.

The Orion academic access experiment led by Andy Higginbotham, University of Oxford (now at University of York) has produced a major publication in Nature Scientific Reports.

The first Orion Academic Access experiment led by Prof Gianluca Gregori, University of Oxford, has had its results published in Nature Communications.

The third annual meeting of the Oxford Centre for High Energy Density Science (OxCHEDS) took place on 4th and 5th of April at Trinity College, Oxford attracting over 40 attendees from AWE and the University of Oxford.

The second annual meeting of the Oxford Centre for High Energy Density Science (OxCHEDS) took place on 30th and 31st of March at Trinity College, Oxford.

On 31st March-1st April 2014 OxCHEDS held its 1st Annual Meeting at Trinity College, Oxford. This two day event was attended by over 50 delegates from within OxCHEDS and AWE. A comprehensive series of talks was presented which covered the entire range of OxCHEDS activities. Nearly 30 speakers discussed topics ranging from astrophysics to QED, with particular emphasis being placed on discussing new areas for potential collaboration.
