Lecture information

Event type: Lecture in study course Master of Science (Physics) / MVSpec: Advanced Lecture on Special Topic (Atomic, Molecular and Optical Physics)

Field of study resp. study course: Master of Science (Physics)

Contact hours: 3/week

Type of lesson: Lecture: Stored Charged Particles (2 SWS), Tutorial with homework (1 SWS)

Short description (please see also content page): The lecture gives insight into the modern and exciting field of precision experiments with stored and cooled particles. The basics are discussed in detail. Ground state properties of nuclei e.g. spin, charge radius, mass and lifetime are important quantities in atomic and nuclear physics. Stored particles provide an ideal atomphysical approach to the precise determination of these quantities. Thus, cooling and storage methods become more and more important.

Mandatory/advantageous previous knowledge, Target Group: This lecture is intended for both bachelor and master students.

Useful literature: please see literature page

Tutorials or exams: tutorial with homework

Course Certificate-Criterions: at least 50% of the exercises and active participation in the tutorial

ECTS points: 4 ECTS points are granted for the course certificate

Remarks: The lecture material is placed at your disposal on the eLearning platform Moodle. Master and Doctoral Theses can be written about this subject area.

The lecture notes are available online on the eLearning platform Moodle in pdf format:
