The Research Complex at Harwell (RCaH) is a science-led national resource with a mission to enable and add value to outstanding new science that benefits, and benefits from, the UK’s Central Facilities. We have a mix of research hubs, individual groups and facilities that fall within the physical, life and laser sciences. About 180 researchers are based here, and we have more than 500 visitors per year. Our priorities are Energy Materials, Advanced Manufacturing, Catalysis, Structural Biology of infectious disease and a cross cutting Correlative and Integrated Imaging theme (with a time domain focus). Engagement with industry is central to delivering our mission and we will continue to develop partnerships with industry. RCaH is part research incubator (the ‘hotel’ model), where university-based scientists apply for grants that they elect to hold at RCaH. Two stakeholders, Science & Technology Facilities Council and Diamond Light Source, strategically allocate their own space. RCaH also help facilitate industrial collaborations and can provide access to high quality equipment. We are conveniently located next to the Diamond Light Source (DLS), the UK Neutron Source (ISIS), the Central Laser Facility (CLF) , Rosalind Franklin Institute and the electron microscopy centre.
