Tracerco is a world-leading industrial technology company providing companies all over the world with the insights they need to make informed decisions about their operations. Our expertise allows customers to operate more productively, effectively and safely. With offices across six continents, Tracerco is a global leader with local values.
The Role
Tracerco are seeking an experienced Research Physicist to join our Product Development and Innovation Department working on the development of advanced radiation instrumentation and detector technologies.
The successful candidate will have the opportunity to contribute to a range of research and development projects from radiation instrumentation concept through to CT design, signal processing and image reconstruction. Radiation transport simulation is central to the role and will drive forward research and support colleagues across the business with physics-based analysis and modelling. In addition, the Physics team are seeking an individual with radiation signal processing experience to contribute to the design and implementation of optimal radiation detectors for application within radiation instruments.
The role involves working in close collaboration with inter-disciplinary teams to translate fundamental physics into practical detector and instrumentation solutions. Physicists are required to engage with the full development chain from understanding of customer and commercial requirements, early-stage concept evaluation and feasibility assessment all the way through development to characterisation, validation and performance optimisation.
Key Responsibilities
Simulation and Radiation Physics
- Maintain and develop Monte Carlo simulations of radiation transport, scatter and detector response using GATE and/or GEANT4
- Model radioactive source and decay characteristics
- Simulate scatter distributions and provide input into the design of anti-scatter correction hardware and algorithms for instrumentation
- Support the optimisation of CT system geometry, source parameters and detector design
- Develop and validate detector response models to support instrumentation design optimisation
- Provide simulation-based analysis for new and ongoing investigations through detector concept evaluation, geometry optimization and shielding assessment
Detector Signal Physics
- Characterise and design signal chains from initial interaction through to digital output
- Liaise with electronics engineers to translate detector physics requirements into signal processing specifications
- Support detector design and array development by providing an understanding of the signal chain
- Develop physics-informed correction algorithms for detector imperfections including scintillator afterglow, gain non-uniformity and pixel crosstalk
- Work closely with CT reconstruction development team to optimise the signal chain with reconstruction requirements and limitations in mind
- Develop an understanding of industrial inspection requirements
- Contribute to the translation of customer inspection requirements into system performance specifications
General
- Work within cross-disciplinary teams to progress radiation instrumentation development and address customer requirements
- Create high quality technical reports and presentations
- Communicate technical results to technical and non-technical stakeholders, customers and business leaders
- Contribute to IP development
