RAF Harwell

Diamond Light Source (or Diamond) is the UK's national synchrotron light source science facility located at the Harwell Science and Innovation Campus in Oxfordshire. Its purpose is to produce intense beams of light whose special characteristics are useful in many areas of scientific research. In particular it can be used to investigate the structure and properties of a wide range of materials from proteins (to provide information for designing new and better drugs), and engineering components (such as a fan blade from an aero-engine) to conservation of archeological artifacts (for example Henry VIII's flagship the Mary Rose). There are more than 50 light sources across the world. With an energy of 3 GeV, Diamond is a medium energy synchrotron currently operating with 32 beamlines.

The National Satellite Test Facility (NSTF) is a testing site for artificial satellites, located in Harwell, Oxfordshire, in the United Kingdom. It is the first dedicated satellite testing facility in the UK. Construction began in 2018 and was completed in 2024. The facility opened in May 2024. The facility was funded by UK government as a result of a facilities gap study led by UK Space Agency, and is operated by RAL Space, a department of the Science and Technology Facilities Council. Its first customers were Airbus Defence and Space UK.

The electron Bio-Imaging Centre (eBIC) is a national facility in the United Kingdom that houses equipment and specialists for structural biology using Cryogenic electron microscopy.

The Atlas Computer Laboratory on the Harwell, Oxfordshire campus shared by the Harwell Laboratory was one of the major computer laboratories in the world, which operated between 1961 and 1975 to provide a service to British scientists at a time when powerful computers were not usually available. The main user population was the UK universities and some government agencies. Now called the Atlas centre, it is home to European Space Agency's (ESA) Business Incubation Centre (ESA BIC), the Space Applications and Telecommunications (ESA ESCAT), and the Science and Technology Facilities Council's (STFC) Innovations Technology Access Centre (I-TAC).

The Rutherford Appleton Laboratory (RAL) is one of the national scientific research laboratories in the UK operated by the Science and Technology Facilities Council (STFC). It began as the Rutherford High Energy Laboratory, merged with the Atlas Computer Laboratory in 1975 to create the Rutherford Lab; then in 1979 with the Appleton Laboratory to form the current laboratory. It is located on the Harwell Science and Innovation Campus at Chilton near Didcot in Oxfordshire, United Kingdom. It has a staff of approximately 1,200 people who support the work of over 10,000 scientists and engineers, chiefly from the university research community. The laboratory's programme is designed to deliver trained manpower and economic growth for the UK as the result of achievements in science.

Nimrod (National Institute Machine Radiating on Downs, "the Mighty Hunter" Nimrod; name attributed to W. Galbraith) was a 7 GeV proton synchrotron operating in the Rutherford Appleton Laboratory in the United Kingdom between 1964 and 1978. Nimrod delivered its last particles at 17:00 hrs on 6 June 1978. Although roughly contemporary with the CERN PS its conservative design used the "weak focussing" principle instead of the much more cost-effective "strong-focussing" technique, which would have enabled a machine of the same cost to reach much higher energies. The design and construction of Nimrod was carried out at a capital cost of approximately £11 million. It was used for studies of nuclear and sub-nuclear phenomena. Nimrod was dismantled and the space it occupied reused for the synchrotron of the ISIS neutron source.

Central Laser Facility (CLF) is a research facility in the UK. It is part of the Rutherford Appleton Laboratory. The facility is dedicated to studying the applications of high energy lasers. It was opened in 1976. As of 2013 there are 5 active laser laboratories at the CLF: Vulcan, Astra Gemini, Artemis, ULTRA, and OCTOPUS. The facility provides both high-power and high-sensitivity lasers for study across broad fields of science from atomic and plasma physics to medical diagnostics, biochemistry and environmental science. Also through the Centre for Advanced Laser Technology and Application (CALTA), CLF is responsible for laser development. DiPOLE is the brainchild of that project.

The European Centre for Space Applications and Telecommunications or ECSAT is a research centre belonging to the European Space Agency (ESA) and located on the Harwell Science and Innovation Campus in Oxfordshire, United Kingdom. It was created in 2009 and moved to its present building in 2013. Staff work on activities linking space to telecommunications, integrated applications, climate change, technology and science.The development of ECSAT was in line with the growing efforts of the United Kingdom in the space sector, including the creation of the UK Space Agency in 2010 and the increase in the economic contribution of that country to ESA. At the same time, ESA benefited from a closer relation with the UK space sector and corrected a historical anomaly whereby the United Kingdom, while being one of the biggest ESA contributors, did not host any of the agency's major centres. There is an earlier ESA facility on the campus, the ESA Business Incubation Centre (BIC) Harwell, which is intended to assist in the development of technology transfer ideas, helping to transform them into viable businesses. ECSAT hosts the ESA Climate Office, responsible for defining and implementing ESA's Climate Change Initiative Programme.

The Harwell Science and Innovation Campus is a 700-acre science and technology campus in Oxfordshire, England. Over 6,000 people work there in over 240 public and private sector organisations, working across sectors including Space, Clean Energy, Life Sciences and Quantum Computing. The site is 2 miles (3 km) outside Didcot, about 15 miles (24 km) south of Oxford and roughly 6 miles (10 km) east of Wantage. A large part of the site was formerly the main research establishment of the United Kingdom Atomic Energy Authority, but it has seen a transition to its new role as a science and business park as the nuclear facilities have been decommissioned.

The National Chemical Emergency Centre (NCEC) is a former UK government agency, now privately owned as part of Ricardo plc, providing information related to chemical accidents (spillages and fires) to emergency services in the United Kingdom and other countries. The NCEC is headquartered on the Harwell Science and Innovation Campus in the Vale of White Horse in Oxfordshire.

The Faraday Institution is a British research institute aiming to advance battery science and technology. It was established in 2017 as part of the UK's wider Faraday Battery Challenge. It states its mission as having four key areas: "electrochemical energy storage research, skills development, market analysis and early-stage commercialisation". The Institution is headquartered at the Harwell Science and Innovation Campus near Oxford. It is a limited company and is a registered charity with an independent board of trustees.

The Harwell Synchrocyclotron was a particle accelerator based at the Atomic Energy Research Establishment campus near Harwell, Oxfordshire. Construction of the accelerator began in 1946 and it was completed in 1949. The machine was of the synchrocyclotron design, with a 1.62T magnet of diameter 110" (2.8m) allowing protons to be accelerated to energies of 160-175MeV. Accelerator physicist John Adams, who later went on to lead design of CERN's SPS, was instrumental in the design and construction of this machine. Its main function was basic nuclear and particle physics research, with a focus on proton-proton and proton-neutron scattering.Comparisons were frequently drawn between the second cyclotron at the Harvard Cyclotron Laboratory and the Harwell Synchrocyclotron, and in 1974 clinicians from Oxford's Radcliffe Infirmary led by Dr T Hockaday floated plans to replicate the proton therapy work carried out at Massachusetts General Hospital with the accelerator. Initial preclinical research took place, including the measurement of proton beams in tissue equivalent plastics as part of the development of phantom materials by researchers at St Bartholomew's Hospital. Interest in this project continued into 1978, when the MRC met to make a funding decision. No clinical trials ever took place and decommissioning of the former AERE site began in the 1990s. Demolition of Hangar 7, which housed both the synchrocyclotron and the ZETA nuclear fusion project, was completed during financial year 2005/2006.
