Laser-driven radiation beamlines at SCAPA

. We propose to create new capability and capacity for collaborative high power laser-plasma research to underpin the development and application of laser-driven radiation sources, using three new beamlines and experiment stations at the Scottish Centre for the Application of Plasma-based Accelerators, SCAPA. Each of the beamlines will be configured in a unique way and with a focus on a specific category of laser-plasma interactions and secondary sources, to create a complementary suite of dedicated beamlines. This approach is required to enable the development and optimisation of laser-plasma sources from the realms of scientific investigation to real-world applications. It enables long-term investment in the optimisation and stabilisation of the beams and largely eliminates downtime for rebuilding experiments, thus enabling efficient and effective use of high power laser beam time. The equipment will support an extensive research portfolio in laser-plasma physics and multidisciplinary applications, with an emphasis on radiation sources and healthcare applications. The unique properties of laser-driven radiation sources make them attractive both as tools for science (e.g. femtosecond X-ray sources for probing the structure of matter) and for applications in a variety of sectors including: healthcare (e.g. imaging and radiotherapy); industry (e.g. penetrative probing and assay) and energy (e.g. testing the integrity of stored nuclear waste). The strategic development of this field requires a balanced programme of dedicated university-scale and leading-edge national laser facilities. The proposed beamlines will complement existing and planned expansion of national facilities at the Central Laser Facility, providing new capability and capacity to enable UK research groups to remain at the forefront of this research area and help promote international collaboration. The research will be performed collaboratively with groups from across the UK and sustained mainly through collaborative research grants. The new suite of beamlines will promote exchanges between academia and industry, and enable engagement of the UK research community with large international projects, such as the Extreme Light Infrastructure, ELI. It will also provide a unique interdisciplinary training platform for researchers. .
