Physik mit Positronen 1

What it is about

You will receive an introduction to physics with positrons and their applications in materials science, solid-state and surface physics. You will learn how positron sources and monoenergetic positron beams are realized and guided, how positrons interact with matter, and how positronium is produced and measured. In the end you will be able to explain common positron measurements and detectors, and in particular positron lifetime spectrometers, and apply them to the investigation of crystal defects.

What you will be able to do

• Explain the production of positron beams
• Explain electrostatic and magnetic beam guidance
• Understand and explain the interaction of positrons with matter
• Describe the interaction of gamma radiation with matter
• Describe particle and radiation detectors
• Describe crystal defects and name suitable positron techniques
• Explain the operation of a positron lifetime spectrometer
• Explain the production and measurement of positronium

What the module consists of
