Course objectives
The student gets an orientation in the basics of electron optics with their application to systems used in electron optics. In particular, a) Paraxial approximation for systems with a straight and curved axis b) Effect of geometric, chromatic and wave aberrations on the resulting electron microscope image c) Effect of misalignment aberrations and their correction d) Methods of correction of geometric and chromatic aberrations
Learning outcomes
After completing the course, the student will be able to: Describe the basic electron-optical properties of a beam in an electron microscope Quantitatively describe the effect of aberrations on the resolution of an electron microscope Describe the influence of misalignment of individual elements of the microscope and to propose methods of their correction
Syllabus
  • Analogy between electron and light optics, Index of refraction, equation of trajectory and conservation of directional current density Description of electromagnetic fields of elements used in electron optics Paraxial approximation: axially symmetrical systems, quadrupoles, systems with curved axis Misalignment aberrations and their correction Basic geometric and chromatic aberration Wave optical description of the electron beam - paraxial description, influence of aberrations.
