Content, Learning Outcome and Preconditions


This module provides an introduction to the physics of positron with its applications in atomic physics and in particular in materials science, solid state and surface physics. After a historical overview different techniques will be presented, how positron sources and mono-energetic positron beams are produced. The interaction of positrons with matter is described to illustrate how positrons are used as a probe to investigate crystal defects on an atomic-scale. With surface analysis as an example the specific differences to techniques, in which electrons are used, are shown. Then a systematic overview of crystal defects and the characterization of the free volume of amorphous solids is given. Then various radiation and particle detectors are presented and their application in positron experiments is discussed. Finally, various spectrometers are presented to investigate electron momentum distributions, defect types and concentrations, element distributions near defects, surfaces and fundamental properties of positronium. Exemplarily some findings of current research are discussed. 


Learning Outcome

After successful completion of this module, the students are able to

  1. understand and explain the interaction of positrons and gamma rays with matter
  2. present particle and radiation detectors,
  3. explain the production of positron beams, and the electrostatic and magnetic beam guidance
  4. explain the operation of positron spectrometers and complementary measuring methods
  5. describe crystal defects and to know positron techniques that are applied to the investigation of it
  6. explain the measurement of the electronic structure of materials
  7. to explain the production and measurements with positronium 


No special prerequisites beyond the ususal Masters degree program.

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Remarks on associated module exams

The exam for this module can be taken together with the exam to the associated follow-up module PH2076: Physik mit Positronen 2 / Physics with Positrons 2 after the follwoing semester. In this case you need to register for both exams in the following semester.

Exam Repetition

The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.
