CSIRO Student project for 2015-16 CSIRO offers opportunities for students to undertake applied physics research projects at our Lucas Height laboratories. Honours projects are normally undertaken on a part-time basis over a period of about 6-7 months during the academic year. A daily stipend is paid to all students. Honours projects H1. Measurement and characterisation of X-ray tube output H2. X-ray Diffraction Modelling About the CSIRO Lucas Heights group Our research group develops novel instruments for minerals and security industry applications. We focus on carrying new ideas from the basic research stage through to industrial demonstration and commercialisation. Our group comprises a mix of students, postdoctoral fellows, scientists, and mechanical, electronic and software engineers. Students would join the nucleonics team, who focus on inventing, designing and building X-ray and nuclear-based measurement and imaging systems. Projects involve a diverse range of skills, including: Computer modelling of radiation, using Monte Carlo tools; Designing, building and operating experimental equipment; Using radiation sources and detectors, including X-ray tubes and high-resolution solid-state detectors; Data collection and analysis using packages such at Matlab; and Report writing. Students would be based at CSIRO’s Lucas Heights laboratories. There are excellent opportunities for interested students to continue their studies by undertaking a PhD project with the group. Honours Project H2 – X-ray Diffraction Modelling Supervisor: Dr Joel O’Dwyer (joel.odwyer@csiro.au) Skills required: This project would suit a student with a strong physics and mathematics background. Experience with Matlab would be an advantage. CSIRO develops analysis systems that measure the mineral components of ores fed into minerals processing plants. These systems use a special version of the X-ray diffraction method to identify the variety and amount of key minerals in the process stream. This information is gathered in real-time and fed back to the plant, allowing the plant operators to optimise the plant conditions based on the mineralogy of the material being processed. This Honours project will aim to develop a computer model to calculate the diffraction pattern of any mineral from an X-ray diffraction instrument. The student will first learn the physics of X-ray diffraction and how this can be used to calculate theoretical diffraction patterns from any crystalline material. The student will then learn how instrument factors affect the quality of a diffraction pattern. This knowledge will be applied to develop a computer code that simulates the diffraction pattern collected by a simple X-ray diffraction instrument. The student will then design and build a simple laboratory X-ray diffraction instrument. A series of experiments will be conducted, and the diffraction patterns of several minerals collected with the apparatus. These patterns will be benchmarked against calculated patterns for the same minerals to test the validity of their modelling code.
