  • Application of Neutron Physics

Aims

The aim of the course is to understand the role of the neutron in Physics and its importance in some of today's applications. In addition, the course aims to describe the Physics principle on which the detection of neutrons is based

Contents

The course deals with the physics of slow and fast neutrons and their main applications: neutron scattering, fission and nuclear fusion. Particular emphasis is given to the Physics principles that are used for the detection of neutrons, including neutron spectroscopy.

Detailed program

1. The neutron as elementary particle.

  • Discovery of the neutron (Chadwick + reading Nature article and other papers)
  • Main properties of the neutron
  • Neutron sources (Radioisotopes, DT generators, spallation pulsed sources)

2. Neutron detection

  • Direct nuclear reactions, compound nucleus, resonance
  • Neutron cross sections
  • Methods for the detection of slow neutrons
  • Methods for the detection of fast neutrons and spectroscopy

3. Neutron Scattering

  • Neutron Scattering in central potential
  • Elastic scattering and diffraction at the Bragg
  • Inelastic scattering

4. Neutrons for the study of condensed matter

  • Diffraction by crystals
  • Neutron spectroscopy
