Japan has many facilities for various quantum beams, including
synchrotron radiation, more than almost any countries in the world.
When you hear the term "quantum beam", you may think of nuclear or
particle physics. However, quantum beams are also widely used in
condensed matter research, such as studies of superconductivity and
magnetism. In April 2024, the 3 GeV high-brilliance synchrotron
radiation facility, NanoTerasu began operation to investigate the
detailed properties of materials.
In this course, you will study the physics?that is, the operating
principles?of the instruments that form the backbone of experiments
using such quantum beams. As a main example, we will focus on
synchrotron-radiation-based Mossbauer spectroscopy, a technique that
lies at the boundary between nuclear physics and condensed-matter
physics. Through this example, the course will cover the key
components of quantum-beam experiments, that is, light sources,
optics, samples, and detectors. The goal is to understand the
principles behind these components as well as to be able to
calculate appropriate experimental conditions of samples actually.
