Course:

Superconducting Accelerator Magnets

Instructors:

Ramesh Gupta and Animesh Jain, BNL


Purpose and Audience
This course will introduce the theory, design, field quality measurements and analysis of superconducting accelerator magnets. New types of magnet designs for future magnets (including those made with high temperature superconductors) will also be introduced. It is intended for those who are either new in this field or considering starting a career in it. It will also be useful to accelerator physicists as they will be able to develop a good understanding of expected field quality in accelerator magnets.

Prerequisites
Electromagnetism at the undergraduate level.

Objectives
The primary objective of this course is to provide a general understanding of superconducting accelerator magnets with an emphasis on magnetic design and measurements. The course will provide the necessary background to start magnetic design of accelerator magnets for a variety of applications. It will also provide a sufficient background to start analyzing magnetic measurements of magnets for particle accelerators.

Instructional Method
The course will consist of lectures, tutorials and computer labs. Commercial and public domain software will be used to carry out a few specific designs and analysis.

Course Content
This course will deal with the theory, design, field quality measurement and analysis of superconducting accelerator magnets. Topics to be covered will include: superconductors (including high temperature superconductors), harmonic description of the field, current distribution for ideal multipole fields, persistent current and quench field calculations, magnetic measurements and the analysis of construction and measurement errors. Results from recent accelerator magnets will be used to help develop an in-depth understanding of field quality during R&D and large scale manufacturing. The course will include computer modeling and error analysis. In addition to the conventional cosine theta designs, the racetrack coil designs will be covered. New magnet designs for future accelerator magnets (including those made with high temperature superconductors) will be discussed. A brief summary of magnet construction and mechanical design will also be provided.

Reading Requirements
(to be provided by the USPAS) "Superconducting Magnets", by Martin Wilson, Oxford University Press (1987). Students will also receive background reading material before the course begins.

Credit Requirements
Students will be evaluated based on performance as follows: final exam (40% of final grade, homework assignments (40 % of final grade) and computer/lab session (20 % of final grade).
