Diamond Annual Review 2025-26

Following internal engagement events and a workshop to better refine the operational model, we have developed a new Operations Division, formed from different groups with key supporting roles. Our search for a new director of this division was successful with the appointment of Dr Francesca Gliubich, who brings operational expertise in a research environment and in bringing teams together. We have also merged our Life and Physical Science Divisions into one single Science Division to provide a more unified approach to planning and strategy. Other changes include a more coordinated approach to planning science activities, and the formation of an operation and delivery group to push decision-making in order to make faster decisions. We believe these structural changes will improve our efficiency and enhance internal collaborations between groups. After we initiated the transformation of Diamond in 2024/25, the past year has seen more significant changes in our organisational structure, driven by a coordinated programme of change. CEOwelcome In addition, these changes will help Diamond to be more responsive to the needs of our user communities and actively support the UKGovernment priorities at a time where facilities need to demonstrate their impact for the nation. In 2025 we also bid a fond farewell to two long-standing members of staff. Professor Sir David Stuart, Life Science Director and Dr Andy Dent, Deputy Physical Science Director, both retired after extensive careers at Diamond (17 and 23 years respectively). A symposium was held for Andy in September 2025, and we will be marking Dave’s scientific contributions at an event in September 2026. Professor Keith Wilson, a member of our Board of Directors, also retired after nine years of service. We thank him for his valuable contributions and support. We welcome Dr Petra Oyston OBE, as our newest Board member who joined in December 2025. In 2025/26, we continued to offer a range of events to provide training, workshops and user events for our community. I am thankful to our advisory committees, Scientific Advisory Committee (SAC), Diamond User Committee (DUC) and Diamond Industrial Scientific Committee (DISCo) for their continued feedback on the delivery of the science. Over the last year we have made significant progress on our Diamond-II upgrade programme with visible milestones achieved. The Diamond Extension Building is now complete and is supporting the assembly of new machine components. As with any major project we continue to tightly monitor and evaluate our progress through a combination of external and internal assessment reviews. I would like to take this opportunity to thank the entire Diamond team, for their diligent work and progress so far. I also thank the members of the Diamond-II Sponsor Group, Machine Advisory Committee (MAC) and the Scientific Software Advisory Committee (SSAC), for their valuable insights and commitment to promoting best practice across our facilities. All this work takes significant effort, especially as we continue to operate the facility while delivering full user operations. I continue to be impressed by the dedication and the engagement of our staff. As we see the enclosures of the new flagship beamlines nearing completion and the new building buzzing with activities, I remain convinced we will overcome daily challenges if we maintain our ambitions and continue to be focused on long-term objectives.
