Module Exam

Description of exams and course work

There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and example calulations.

For example an assignment in the exam might be:

  • Give the equation which defines the wave length of matter. Discuss the dependencies write down the fission reaction.
  • Warum müssen Spaltneutronen moderiert werden? Was bedeutet Moderation?
  • Beschreiben Sie den Energietransfer bei elastischen zentralen Stößen.
  • Nennen Sie typische Moderatoren. Diskutieren Sie den Unterschied von D2O und H2O als Moderator. Wie groß ist die Diffusionslänge in beiden Moderatoren?
  • Diskutieren Sie die Unterschiede / Komplementarität von Reaktorneutronenquellen und Spallationsneutronenquellen.
  • Beachten Sie die verschiedenen Wirkungsquerschnitte für thermische Neutronen. Was ist die Einheit für einen Wirkungsquerschnitt?
  • Wie ist die Beziehung zwischen Sigma_Coh und Streulänge b?
  • Geben Sie die Definition des doppelten Differentialquerschnitts für thermische Neutronen an.
  • Was ist der Streuvektor.
  • Wie lautet die Laue-Bedingung in der Beugung? Was bedeutet diese?
  • Wie lautet die Bragg-Bedingung? Was beschreibt sie?

Remarks on associated module exams

The exam for this module can be taken together with the exam to the associated follow-up module PH2054: Physics with Neutrons 2 / Physik mit Neutronen 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.
