About the Project
The influence of imperfections in the devices (bulk material and surface effects – the latter depending on device fabrication (surface processing and metallisation)) on the performance and stability is still not very well understood. Furthermore, materials with higher atomic number than the diamond itself (for example within the metallisation and device mounting and packaging), may cause dose enhancement near the interface and hence modify the pumping and priming behaviour of devices. Hence, this project will characterise the performance of high quality industrially reproducibly fabricated prototype diamond dosimeters in clinically relevant radiation fields.
The work shall be complemented by fundamental charge transport studies and simulations in order to identify the underlying mechanisms determining device performance with the aim of defining the specifications for a commercial dosimeter. It is expected that a device design for a commercial macro-dosimeter will be determined throughout the duration of the project. If possible, the work shall then be expanded to micro-dosimetry devices, which is of particularly importance for the development of new treatment modalities coming online, namely proton and carbon therapy.
The project is a collaboration between the University of Surrey (Radiation and Medical Physics Group: https://www.surrey.ac.uk/radiation-and-medical-physics-group) and Micron Semiconductor Limited.
This is a three project, commencing in April 2020.
UK or EU applicants who hold a First or 2:1 UK honours degree in a relevant subject area, or a 2:2 alongside a good masters degree (a distinction is usually required). If English is not your first language, you will be required to have an IELTS Academic of 6.5 or above (or equivalent), with no sub-test score below 6.
