| 651-0046-00L | Electron Microprobe Course 1 - Theory | 2 credits | 2G | J. Allaz, L. Grafulha Morales | |||||||||||||||||||||||||||||
| Abstract | Theory on scanning electron microscope (SEM) and on electron microprobe analysis (EPMA) applied to geological materials. Complete presentation of the instrument, interaction of electron with matter, principles of electron imaging (SE, BSE and CL), of electron backscatter diffraction (EBSD), and of X-ray analysis for the chemical characterisation of solid material at the micron-scale. | ||||||||||||||||||||||||||||||||
| Learning objective | Understand how the instrument works, why it is used, and how the different signals are being generated and analysed. Ability to treat and to present analytical results, such as calculating a mineral formula from a mineral analysis. | ||||||||||||||||||||||||||||||||
| Content | Physical principles of electron optics, interaction of electrons with matter, production of X-rays, interaction of X-rays with matter, X-rays detection and analysis. The course includes some live demonstrations on the instrument (remotely). | ||||||||||||||||||||||||||||||||
| Lecture notes | Script will be provided. | ||||||||||||||||||||||||||||||||
