Magnetic Systems course

Sponsoring University:

University of Texas at Austin

Course:
Magnetic Systems: Theory and Design for Accelerators and Detectors, with Emphasis on Insertion Devices

Instructors:
Ross Schlueter and Soren Prestemon, Lawrence Berkeley National Lab

Purpose and Audience
The course will focus on various theoretical and practical topics of magnetics as applicable to accelerator magnets with special attention given to insertion devices, which are the high performance radiation sources for synchrotron and FEL facilities.

Prerequisites
An undergraduate Classical Mechanics and Electromagnetism course.

It is the responsibility of the student to ensure that they meet the course prerequisites or have equivalent experience.

Instructional Method
The course consists of lectures in both morning (3 hrs. per class day) and afternoon sessions (minimum of 2 hrs. per class day). In addition, afternoon exercise sessions are planned to assign and explain homework each day.

Course Content
This course introduces the fundamentals of the design of electromagnet, pure permanent magnet, superconducting, and hybrid iron/permanent magnet systems and gives a broad and practical overview of design issues. Special attention is given to insertion devices for synchrotron storage rings and FELs, though other accelerator and detector magnets are covered as well. Emphasis is on practical engineering and magnetics issues, emphasizing underlying physical and mathematical principles.

The stage is first set with magnetics fundamentals, beginning with a review of Maxwell’s equations, then progresses to cover various magnetics topics, including:
(1) theory of electromagnet, permanent magnet, superconducting, & hybrid magnet design,
(2) storage ring, accelerator, and detector magnets,
(3) wiggler and undulator requirements and performance,
(4) field strength and quality issues,
(5) polarization,
(6) magnetic forces,
(7) coil construction and cooling,
(8) permanent magnet sorting and quality,
(9) superconducting magnet considerations and issues,
(10) field errors in insertion devices,
(11) pitfalls in magnet design and construction,
(12) radiation codes and radiation characteristics
(13) novel insertion devices

Reading Requirements
Instructor notes on "Magnetics Systems/ Insertion Devices" to be provided by the USPAS.

Credit Requirements
Students will be evaluated based on performance: final exam (40 % of final grade), homework assignments (60 % of final grade).
