651-0046-00L Electron Microscopy Course (SEM and EPMA)
| Semester | Autumn Semester 2023 |
| Lecturers | J. Allaz, L. Grafulha Morales |
| Periodicity | yearly recurring course |
| Language of instruction | English |
| Abstract | Theory and lab demo of scanning electron microscope (SEM) and electron microprobe analysis (EPMA) applied to geological materials: introduction to the instruments, interaction of electron with matter, electron imaging (SE, BSE, CL), electron backscatter diffraction (EBSD), 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 microscopy: electron optics, interaction of electrons with matter, production of X-rays, interaction of X-rays with matter, X-rays detection and analysis. The second part of the course includes several demonstrations on various SEMs (at ERDW and ScopeM) and one EPMA at DERDW. | ||||||||||||||||||||||||
| Lecture notes | Script will be provided, along with copies of the course presentations. | ||||||||||||||||||||||||
