ENVISAGE: Evaluating gamma-imaging with the SIGMA detector

Reference number: PPPR065

Description

The Department of Physics at the University of Liverpool is seeking to recruit an outstanding individual to join the Nuclear Physics research group as a PhD student. The research project, a collaboration between the University of Liverpool and Mirion Technologies, will optimise the operational performance of the Segmented Inverted Coaxial Germanium (SIGMA) detector as a gamma-ray tracking and imaging device. The project will also ENVISAGE the design of the next generation imaging detector SIGMA2.

The ability to precisely measure the energy of gamma radiation is essential in the study of nuclear structure using gamma spectroscopy. The gamma decay scheme of a nucleus is unique and provides an unprecedented insight into its microscopic structure. This nuclear “fingerprint” is also an essential ingredient of gamma imaging which has wide application in the fields of (for example) nuclear decommissioning and diagnostic medical imaging. Gamma imaging also requires precise knowledge of where the gamma photon has originated from which places constraints on the optimal design of the detector.

The SIGMA detector is designed to offer unrivalled performance over other large volume germanium detectors. Evaluation and validation of the SIGMA gamma-ray tracking detector in relevant environments (ENVISAGE) is a UKRI funded research project to demonstrate the potential of this imaging technology and to optimise the detector design for the next generation of nuclear physics experiments and industrial/medical applications. The PhD student will join this research project and will make a leading contribution to the deployment of the prototype SIGMA detector at the University of Jyväskylä accelerator laboratory (JYFL). This work will evaluate the performance of the detector and will address questions in nuclear structure and nuclear astrophysics using the decay spectroscopy technique. The PhD project will also evaluate the performance of SIGMA as a spectroscopic gamma-ray imager in a nuclear decommissioning environment to locate, identify and quantify gamma radiation. The findings of this work will inform the design of the next generation SIGMA2 detector.

 

The successful applicant will participate in the design, setup and execution of experimental work and will carry out the analysis of data from these experiments. They will work on the simulation packages required for radiation detector development and will have the opportunity to work closely with Mirion Technologies and international laboratories. Experience with radiation detectors or scientific computing would be an advantage. You will receive an annual stipend and payment of tuition fees for 3.5 years.
