Course:

Magnetic Measurements

Instructor:

Henry Glass, Fermilab

This course will cover the concepts and practical methods for the measurement of accelerator magnets, including superconducting magnets. We will introduce the principles of magnet design through the use of complex analysis and 2-dimensional multipole expansion. The measurement methods to be discussed include harmonic coils, search coils, stretched wires, Hall and NMR probes. There will be an overview of magnetic materials and permanent magnets. The last part of the course will concentrate on the special considerations for superconducting magnetic measurements. This will include an introduction to topics including cryogenics, superfluidity, superconducting strands / cables, quench protection, and persistent current effects. The techniques will be illustrated by examples from ongoing magnet R&D and production projects, including the Fermilab Main Injector and Recycler, and the CERN Large Hadron Collider. Knowledge of electromagnetism and familiarity with complex variables are required.
