Research Assistant for National Electron Microprobe Laboratory, Temporary Position

The Department of Earth Sciences is Sweden's most comprehensive academic environment for research and education in earth sciences. Here you will find broad expertise that contributes to solutions for important societal challenges. Earth is a dynamic planet that is constantly changing. To understand how our planet works, our researchers seek answers in the field, through laboratory experiments, and advanced models. Our research and education cover a wide range of areas; rocks and minerals, weather and climate, the evolution of life, natural disasters, wind power and energy, environmental and water engineering, and sustainable development. Our research combines natural science and engineering with social science and is often interdisciplinary. The department employs over 300 people from more than 30 countries, both in Uppsala and at Campus Gotland. Our six research divisions: • Geophysics • Air, water and landscape science • Mineralogy, petrology and tectonics • Natural resources and sustainable development • Paleobiology • Wind energy For more information see: https://www.uu.se/institution/geovetenskaper Research and education within the Mineralogy, Petrology and Tectonics program at the Department of Earth Sciences is conducted primarily within three integrated fields: mineralogy, petrology, and tectonics. The program operates a new Field Emission Electron Probe Microanalyzer (JXA-8530F JEOL HYPERPROBE), equipped with five crystal spectrometers (WDS), secondary (SE) and backscatter electron detectors (BSE). The instrument performs quantitative chemical analyses at a micrometer scale and imaging of minerals or materials down to a nanometer scale. Quantitative analyses of elements are possible in the range from beryllium to uranium. Job Responsibilities The research assistant will be responsible for operation and maintenance of the FE-EPMA and general management of the laboratory. In addition to routine operation and customer service, responsibilities will also include development and implementation of new micro-analytical methods such as in-situ chemical dating, trace element-based geothermobarometry, and basic analysis of volatile elements (depending on demand). Responsibilities will also include assisting students using the EMPA and training related to the role focus. Qualification Requirements Master's degree in mineralogy and/or petrology. Experience with Field Emission Electron MicroProbe and conventional electron microprobe is required. The applicant should also have a background in other electron-based micro-beam techniques such as SEM-EDS-EBSD and parallel techniques: Raman spectroscopy and practical understanding of mass spectrometry methods (e.g. LA-ICP-MS) applied to rock-forming minerals. Desired/Meriting Qualifications Practical experience with JEOL EPMA instruments (and specifically JXA-8530F Field Emission EPMA) is highly meriting. Experience in preparing EPMA datasets for thermodynamic modeling and geochronology is also highly meriting. It is desirable that the candidate has documented strong knowledge in modern mineralogy and petrology. Ability to build and develop professional networks with colleagues and to maintain close contact and collaboration with other institutions and laboratories worldwide is meriting. Knowledge of Swedish bedrock and training experience is meriting. The evaluation of applicants will be weighted equally on scientific competence, technical skills, and experience with the relevant instrumentation.
