[3][4][5] Quantum Detectors is based at the Harwell Science and Innovation Campus[6] close to the city of Oxford in the United Kingdom (UK).

The SRS being one of the first synchrotrons used for beamline users,[8] there were few detectors available during its early years, requiring development of new systems for each application where commercial solutions were not available.

This led to a number of novel detector systems, some of which were sold by the operator of the SRS to other facilities internationally, such as the ESRF,[9] SPring-8[10] and the Photon Factory.

[11] These detectors included Xspress, XSTRIP and RAPID, updated versions of which can all be found at the Diamond Light Source today.

Diamond opened in January 2007 and the SRS closed in August 2008, leading to the relocation of Quantum Detectors to Harwell to stay with the UK's Synchrotron Facility.
