Magnetic Systems for Accelerators, Detectors and Insertion Devices

Sponsors:

University of California, San Diego Extension

Course Name:

Magnetic Systems for Accelerators, Detectors and Insertion Devices

Instructors:

Ross Schlueter, Diego Arbelaez and Soren Prestemon, Lawrence Berkeley National Laboratory

Purpose and Audience
The course will focus on various theoretical and practical topics of magnetics as applicable to the design of magnets systems for application to charged particle accelerators.  Applications will include those of (i) lattice magnets, which guide the beam, (ii) detector magnets, and (iii) insertion devices, which generate the high-performance radiation sources for synchrotron light sources and Free Electron Laser (FEL) facilities.

Prerequisites
Junior level undergraduate Classical Mechanics and Electromagnetism are required. Some familiarity with accelerator physics at the level of USPAS Fundamentals of Accelerator Physics and Technology with Simulations and Measurements Lab is recommended.

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.  Instructors will be available for guidance during evening homework sessions.

Course Content
This course introduces the fundamentals of the design of electromagnet, pure permanent magnet, superconducting, and hybrid iron/permanent magnet systems. A broad and practical overview of design issues is presented. Attention will be given to (i) lattice magnets, which guide the beam, (ii) detector magnets, and (iii) insertion devices for storage ring based light sources and FELs. Emphasis is on practical engineering and magnetic material issues, while developing underlying physical and mathematical principles employed design of magnetic systems.

The course first overviews magnet fundamentals, beginning with a review of Maxwell’s equations, then progresses to cover various magnetics topics, including:
(1)   Theory of electromagnet, permanent magnet, superconducting, and hybrid magnet design. 
(2)   Magnets for accelerators, storage rings, and detectors.
(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) 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: comprehensive final exam (40 % of course grade), homework assignments (60 % of course grade).
