Evaluation of digital SPAD imaging arrays to scintillator based radiation detectors – Kromek Ltd and the Universities of York and Edinburgh

In recent years there has been a gradual replacement of conventional photomultipliers tubes by new analogue semiconductor technologies in the scintillator based radiation detection market. These technologies are expected to mature further with the emergence of digital semiconductor imaging technologies. In both cases the technology is driven forward in the beginning by applications in light sensing and imaging and later applied to radiation detection. This project will investigate the feasibility of using digital SPAD (single photon avalanche diode) technology developed at University of Edinburgh across a wide range of radiation detection requirements and will identify the areas of improvement required for this technology to find commercial application in radiation detection and create a feasible plan for further work that would lead to application in the radiation detection market.

Kromek has a long-standing relationship with the University of York, who have extensive experience and facilities for characterization of radiation detectors and this project will see a collaboration between Kromek, Edinburgh and York with the aim of seeding a process which will see an accelerated commercialization path for digital SPAD technology.
