This course is meant as an introduction in magnet technology focusing on normal-conducting, iron-dominated electro-magnets.
The main goals are to create a fundamental understanding of electro-magnets used for particle accelerators and beam transfer lines, to provide a guide book with instructions how to start with the design of a standard accelerator magnet and to present aspects related to magnet construction, manufacturing, testing and measurements.
The theoretical part will be interleaved by a number of practical examples and a case study where students will design a real-world magnet for a medical particle accelerator. From the contents:
1-Introduction: Historical background. Basic principles and concepts of accelerator magnets. The role of the magnetic circuit. Particularities of magnetic steel. Magnet types and their functions
2-Analytical magnet design: Understanding the requirements. The analytical design process. Magnet components and their purpose. Designing the magnetic circuit. Coil dimensioning and cooling layout
3-Magnet manufacturing: The magnet lifecycle. The manufacturing process. Material selection: magnetic steel, insulation materials, conductor materials. Modern production techniques. Auxiliary magnet components. Cost estimates and cost optimization
4-Quality assurance: Sample testing. Evaluating the performance of a magnet. Recurrent quality issues. Magnetic measurement techniques
5-Applied numerical design: The numerical design process. Building a 2D finite-element model. Interpretation of results. Improvement of the field quality and pole profile optimization. The importance of mechanical tolerances and the consequence of assembly errors. Limitations of numerical calculations
