Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

| Description | We have discovered that complex structural forms of matter are created on nano-second timescales at extreme pressures and temperatures. This was unknown prior to our work, and the results have since formed the basis of a new successful funding application to EPSRC in 2018. Our results at the LCLS have established the UK as a leader in the field of XFEL studies of matter at extreme conditions. We will develope this further at the European-XFEL in Hamburg from 2020. The students and postdocs funded by this award have been highly sought after by other labs once they had finished in Edinburgh. Three are currently postdocs at Lawrence Livermore National Lab in the US, another is a fellow at the SLAC National Accelerator Lab, and another is a researcher at DESY. |
| Exploitation Route | Our continuation funding from EPSRC requested explicit funding to further develop UK research at the European-XFEL. We see this as a key impact of our new grant. |
| Sectors | Aerospace, Defence and Marine |
| Description | The findings from the LCLS have been presented to AWE as a demonstration of how the techniques utilized can benefit their own research programme. As a result, they are very interested in becoming involved in the European-XFEL research programme from 2018. This has resulted in the award of a CASE top-up from AWE for an EPSRC studentship starting in Sept 2019 The results of the research obtained in this award form part of the science case for a UK-FEL, to be submitted in mid-2020. |
