"Insertion Devices"

Lectures by Professor J. A. Clarke (ASTEC - Daresbury LAB, STFC, UK)

26 - 27 March 2009 in Würzburg

Aims:

The first part of the course gave a brief overview of the properties of synchrotron radiation as generated by the three main types of sources: dipoles, wigglers and undulators. The second part of the course concentrated on how undulator sources are physically realized using the available magnet technologiees; permanent magnets, electromagnets and superconductors.

Program:
