Professor Nicholas Bazin gained his PhD at Brunel University in 1996 studying Sol-Gel Science. Following this he spent the next 15 years in the defence sector developing a number of novel materials and coatings for plasma physics experiments. It was here he was first introduced to X-ray computed tomography running a Target Fabrication Materials Development and Characterisation group where he trained up on an early X-Radia 400 mXCT instrument. He was seconded to the Lawrence Livermore National Laboratories supporting collaborative UK/US research activities in 2014. On returning to the UK, he began investigating the concept of high energy radiography and computed tomography as an assurance tool. Initially looking at the concept of compact fast neutron imaging and high energy X-rays it became apparent a high energy X-ray source was the more viable option. Whilst neutrons did have unique advantages over X-rays, the maturity and ease of use of linac based X-ray systems quickly proved to be the preferred choice. His program of work and his extensive team now cover multiple areas of high energy XCT development from laser driven sources to scintillator development culminating in numerous national awards including the 2022 MoD Quality Award for Best Improvement Concept, 2023 MoD Chief Scientific Advisor Award and a 2024 IOM3 Defence and Security Award. Current work is focused on the design manufacture and assessment of two tungsten based RQIs comparing different systems, scanning parameters and data analysis techniques.
