Abstract

The University of Leicester also has a unique heritage in space instrumentation; every year since 1967 has seen a Leicester-built instrument operating in space. Leicester is particularly well known for its work in X-ray astronomy and planetary science, designing and building detectors of high energy photons for space missions such as XMM-Newton, Beagle 2 and BepiColombo. The detection of high energy photons is also important for aspects of medicine, nuclear power and security, and for characterising materials in sectors like manufacturing, mining, and archaeology.

This project aims to build research, innovation and translation programmes based on core STFC funded research through investigating technology designed for detecting high energy photons in space and applying these to terrestrial applications.

One key application is medical imaging. A portable gamma camera has been developed at the University of Leicester that has made use of similar technology to that developed for the XMM-Newton EPIC X-ray camera. Medical gamma cameras, which are used for a wide range of medical diagnostic tests including determining whether cancer has spread to other areas of the body, can take up a whole room in a hospital. The portable camera developed at Leicester is small enough to be hand held and so it can be brought to the patient wherever they may be, even in the operating theatre. This could make a big difference to surgeons, who currently perform radioguided surgery with a non-imaging detector, which beeps when detecting radioactivity (similar to a metal detector). The gamma camera can show the position and shape of any radioactive sources, in addition to showing their location on an optical overlay, which should greatly help surgeons in localising sources within the body, reducing surgical trauma and improving patient outcomes.

As the detection of high energy photons has a wide array of applications, and the portable gamma camera from Leicester includes unique technology for combining high energy photons invisible to the naked eye along with visible light, there is potential to transfer this to a number of other sectors. Part of the project will entail adapting this platform technology for testing in target environments to determine whether it can be of interest to other industries. Adaptations of the gamma camera have the potential to open up research and commercialisation in a wide number of sectors.
The fellow will also be involved in the University of Leicester's research into novel detector materials. Semiconductors (silicon being the most commonly used) are vital components in all sorts of electronics, including detectors. Novel compound semiconductors are varied and many are 'tunable', able to exhibit different properties depending on their chemical makeup. Detectors made from new semiconductor materials may, for example, be far more sensitive to high energy photons than silicon, or may be able to operate at far higher temperatures. This opens up applications in a range of industries, including in nuclear security. The fellow will work with lead players in the UK nuclear security sector to determine gaps in current detector provision where new materials would be useful, and will then work to investigate materials to fill that gap.

The fellow will have the full support of the University, which will provide high quality training in a number of key areas related to knowledge transfer and innovation. Sectorial specific training will also be provided by industrial partners. Embedding this experience within the department will accelerate current and future commercialisation projects, and further capitalise on funding provided by the STFC.

Description The objective of this project was to explore ways in which the technology and science developed as part of the core STFC programme could be translated to other areas of society. We have translated gamma detector technology (based on research developments for X-ray astronomy) to the medical and nuclear sectors. The technology has now been licensed and will soon be available commercially to hospitals for diagnostic imaging (e.g. thyroid conditions, cancer). We have identified areas in post-operation clean-out (a step in nuclear decommissioning) where the same technology could save time and money as nuclear sites such as Sellafield are being returned to their original environmental statement - the imaging systems we work with had to be rearranged to be suitable, but are now ready for testing on site (expected Q3 2023). Both of these projects show how STFC's fundamental science funding can lead to technologies that benefit society. Since the initially appointed fellow, Dr Sarah Bugby, left to lead a new research group at Loughborough University, the role was taken over by Dr Ivan Reading. His work has explored new directions for research to build on the group's high-speed, low noise, single photon imaging capabilities developed for astronomy and particle physics. It was discovered that these might be usefully applied to develop the detection of ultra-weak photon emission from biological materials as a research and medical diagnostic tool and he has been central in assembling an interdisciplinary consortium of researchers from across the departments of Physics and Astronomy, Chemistry, Molecular and Cell Biology and Genetic and Genome Biology which is now in regular contact and applying for funding for collaborative projects to develop this area with promising practical applications. Other areas of interest which he has investigated include optical ballistic tomography (now the subject of a Ph.D. studentship), and the development of sensors with the ability to detect small signals in sunlight by rejecting strong ambient illumination. He has also led research the interaction of biological materials with mid-infrared wavelengths at 2.94um for the inactivation of water containing pathogens such as bacteria and viruses with a view to controlling the spread of infectious disease (motivated by the Covid pandemic which overlapped this award) - this was investigated under a proof of concept award but is yet to produce definitive results of efficacy.
Exploitation Route The gamma camera technology has been commercialized and is being evaluated in applications for researchers and clinicians in the fields of medical imaging and diagnostics, and in the nuclear industry for poste operation clean-out in nuclear decommissioning. Ultra-weak photon emission is a promising tool with applications in biology, medical diagnostics, and food safety, which we are seeking funding for, and intend to develop further. The research in optical tomography, led by the PhD student under the supervision of Ivan and supported by the interdisciplinary consortium has led to some novel findings and we anticipate developing these through a funded programme.

Description There has been ongoing work with Seracam (https://www.seracimagingsystems.com/seracam/) of the commercialized hand-held gamma camera. An additional license agreement has been negotiated with Serac, based on developments of the camera software and knowhow developed at Leicester from collaboration with the nuclear industry.
